PostgreSQL has built a global reputation of competence and efficiency due to its user-friendly features, integration with other tools, and over 30 years of active development. However, those considering using PostgreSQL for their database management operations must develop an in-depth understanding of the platform and tools it can be integrated with. 

What Is PostgreSQL? 

PostgreSQL is the brainchild of Michael Stonebraker and is rooted back to the Ingres project conducted at the University of California, Berkeley. Its creator, in 1985, began working on the post-Ingres project with the aim of addressing database challenges that had become prominent during the 1980s. 

Although Postgre was developed on the ideas of Ingres, it had a completely different code. In addition, it ensured that the databases could understand the relations between data sets and were able to retrieve information when required. Today, Postgres can provide support for both relation and non-relational data types. 

It supports various SQL functions, including foreign keys, sub-queries, triggers and more. In addition, it can be integrated with a PostgreSQL graphic user interface (GUI) client of a business’s choosing for advanced data management operations. A PostgreSQL GUI client is a management tool that enhances query functions and enables data visualisation and analysis. 

Why Should You Use PostgreSQL? 

PostgreSQL is an expandable and versatile solution that can be used to perform specialised use cases, including geospatial data storage and linking to other data stores. Harnessing such capabilities allows businesses to stay on par with technological advancement. However, that is now all that makes using PostgreSQL a necessity. 

Due to its open-source structure, the solution is free from licensing restrictions, over-deployment, and vendor lock-ins. In addition, PostgreSQL database solution comes with support for a number of programming languages that make adapting to the platform easier. These programming languages include Perl, Ruby, Python, and C++. 

Benefits of PostgreSQL

Decades have passed since PostgreSQL was first launched, however, it continues to be one of the best database solutions available today. Along with being free and open-source, some of the other benefits of PostgreSQL include: 

Ensures Business Continuity 

Ensuring operational continuity in the event of a disaster is a common concern among businesses worldwide. A major benefit of PostgreSQL is that it allows organisations to ensure the successful implementation of their business continuity and disaster recovery strategies (BCDR). Organisations can ensure this by configuring replication methods across multiple servers. 

Supports Multiple Programming Languages

Another advantage of PostgreSQL is that it supports a number of programming languages, such as Ruby, C++, and Python. Such support ensures that organisations do not need to hire additional personnel to use PostgreSQL. In addition, it increases developers’ efficiency and ability to adapt as they are not required to learn additional programming languages. 

Improves Performance and Scalability 

Larger business organisations often require greater authentication and read/write speeds. A significant substantial perk of PostgreSQL is that it allows organisations to use various performance optimisation measures. Some of these measures include geospatial support and unrestricted concurrency. Such support allows PostgreSQL to function efficiently when performing extensive data analysis across multiple data types. 

Ensure ACID Compliance 

A crucial advantage of PostgreSQL is that it ensures atomicity, consistency, isolation, and durability (ACID) compliance during data transactions. Such compliance is a primary concern as it’s often seen as a representation of expected data storage and modifications. These compliance measures help organisations maintain data integrity and avoid data validation errors. 

Top 5 Tools For Managing PostgreSQL Databases 

PostgreSQL can be integrated with a number of tools that streamline database management operations. The exact tools an organisation uses will depend on their requirement and capabilities. Some of the best Postgres tools include:

dbForge Studio 

dbForge studio is one of the best Postgres tools for data management and analysis. It allows users to create, develop, and execute queries. In addition, it allows them to make changes to the data as per their requirements. The tool comes with a number of great features, some of which include performance tuning, query plans, and execution diagrams. 

pgAdmin 

pgAdmin is one of many Postgres tools developers can use to manage databases. It is compatible with multiple operating systems, including Linux, Windows, Unix, and macOS. In addition, it can also be operated as a browser-integrated application. One of the highlight features of pgAdmin is that it enables faster data entry, debugging, and editing of standard objects. 

DBeaver 

DBeaver is a free and open-source database management tool that can be integrated with PostgreSQL. The tool has been designed to manipulate data, create analytics reports and export information as required. In addition, it supports advanced management functionalities such as database monitoring and schema migration.

Here, we take on the idea of network devices from scratch to help you sort through that fuzziness. We’ll begin with a definition, go over our list of network devices, and then talk about some of the crucial factors to bear in mind when managing network devices.

How do network devices work?

Building blocks known as network devices enable communication between services and the endpoints that use those services. In other terms, they are connectors that allow networked device communication.

Anything that aids in data transmission between two devices on a local area network (LAN) is considered to be a communication enabler.

Stopping communication from happening is limiting communication. A firewall rule that blocks traffic from TCP port 23 or a VLAN that divides broadcast domains are two examples of this.

You’ll notice that “hardware” isn’t included in our definition of network devices. This is as a result of the large number of virtualized or software-based network appliances and functions. You could, for instance, set up a virtual appliance that serves as a firewall, network switch, or router.

A crash course in OSI models and data kinds

Knowing a little bit about the layers of the OSI (Open Systems Interconnection) model is one of the best ways to comprehend the function of various network devices. The OSI model offers a conceptual framework for understanding how data moves across and within networks call-tracking.org .

These two features of the OSI model will aid in comprehending how various network devices operate:

• The OSI model consists of seven layers, with the physical layer (Layer 1) being the bottom layer and the application layer being the top layer (Layer 7). Network hardware is frequently described in terms of the OSI layer it operates at.

• The protocol data unit (PDU): Headers and footers are removed as data is processed at various layers of the OSI model, changing the type of PDU that is transmitted. For instance, the IP header is not required when data transmitted at the network layer (Layer 3) is processed at the transport layer (Layer 4). At Layer 3, the PDU with the IP header was a packet. Without the IP header, the PDU at Layer 4 is a segment. You can better understand the language used to describe various networking devices by being familiar with the different PDUs.

11 various types of network devices

1. Firewall

Depending on a set of rules, a firewall is a network security device that monitors traffic and either blocks or permits it. Software, hardware, or a hybrid of the two can be used to create firewalls. Additionally, firewall rules can be based on simple criteria like ports and IP addresses or they can apply heuristics to spot malicious activity.

Network firewalls frequently come as instances in:

·  Firewalls that filter traffic using packets: These firewalls work at Layer 3 and Layer 4 and use rules based on IP addresses, port numbers, and packet types to decide whether to discard or forward traffic. This straightforward method of traffic inspection has the advantage of having little effect on network speed.

·  Stateful-inspection firewalls can track and “understand” when a TCP connection has occurred, in contrast to packet-filtering firewalls. As a result, reply traffic can get past the firewall without specific rules being required. Stateful-inspection firewalls are hence simpler to configure than packet-filtering firewalls, but they may add a little more overhead during inspection and slow down traffic a little more.

·  Application firewalls: These Layer 7 firewalls can distinguish between legitimate and malicious behavior for protocols at the application layer, such as HTTPS, SSH, and SMTP. Application firewalls come in two main varieties: proxy firewalls that offer URL filtering and WAFs (web application firewalls), which defend against XSS and SQL injection attacks.

·  Appliances for unified threat management (UTM) and next-generation firewalls (NGFWs): The debates about whether UTMs and NGFWs are the same thing or not will be saved for another time. These two widely used kinds of firewalls generally have a lot in common. These more sophisticated network security tools not only offer the functionality of the other kinds of firewalls we’ve covered, but they also include cutting-edge capabilities like deep packet inspection (DPI), heuristics that can detect malware, and examination of encrypted traffic.

2. Switch

A network switch is typically described as a Layer 2 device that transmits and receives frames. The fundamental component of Ethernet networks are switches.

Here is a simple illustration of how a Layer 2 switch operates:

·  A mini LAN is created when devices are connected to the switch using Ethernet cables (like a Cat5e or Cat6 cable).

·  The linked devices’ MAC addresses are acquired by the switch.

·  The switch detects the MAC address in the packet and transmits the traffic only to that device when it has to reach a certain device.

Comparing the switch to network hubs, the switch breaks up collision domains by directing the data to a specified device, significantly lowering network congestion. The primary advantage of a Layer 2 switch is the splitting up of collision domains.

But this straightforward illustration of a Layer 2 switch is only one of the various kinds of network switches. The following is a list of typical network switch types:

·  Unmanaged switches merely offer Layer 2 switching for Ethernet frames. No more administrative or configuration features are provided by them. Switches with Power over Ethernet (PoE) functionality are able to connect to the network and power connected devices. PoE switches are frequently used to power Voice over IP (VoIP) phones, for instance. PoE switches come in controlled and unmanaged varieties and can be Layer 2 or Layer 3 switches.

·  Switches that are managed: The characteristics and functionalities of managed switches vary widely. As an illustration, some managed switches are designed for gamers to use at home, while others are designed for large businesses to use on corporate networks. The ability to generate VLANs is one of the most crucial features of a controlled switch (virtual LANs). QoS (quality of service), which prioritizes particular types of traffic, and Spanning Tree Protocol (STP), which prevents network loops, are further characteristics of managed switches that are widely used. Layer 2 or Layer 3 switches are both examples of managed switches.

·  Layer 3 switches: These switches also provide Layer 2 functionality, but they also include Layer 3 routing. Layer 3 switches are capable of packet routing between networks and are IP address aware.

·  Switches that can be “stacked” include some network switches. To function as a single logical switch, these stackable switches can be joined to one another. A good technique to expand a network’s capacity is by stacking switches. For instance, from the administrative and functionality standpoint, stacking two 24-port switches would result in a single 48-port switch.

3. Entry point

Access points (APs), commonly referred to as wireless access points (WAPs), are the network switches of the wireless world that operate at Layer 2. WAPs enable communication between other Wi-Fi devices by connecting to a LAN via a wired link. WLANs are the networks that WAPs create (wireless local area networks).

There are three basic categories of APs, broadly speaking:

·  Fat access points are often referred to as autonomous access points (APs). Traffic from fat APs’ Wi-Fi radios is forwarded straight to the wired network. Access control lists, Wi-Fi encryption, DHCP server capability, and QoS are all easily accessible through the interfaces of these WAPs. The advantage of fat APs is that everything you need to configure and manage the device is already built into them, making them an all-in-one solution.

·  Thin APs: These APs don’t provide all of an autonomous AP’s features. Instead, they route Wi-Fi traffic through a centralized WLAN controller, which takes care of all the forwarding and functionalities a fat AP would normally handle on its own. Large-scale deployments may be simpler to manage thanks to this centralized approach to WAP management, despite some trade-offs associated with thin APs’ constrained functionality.

·  Fit APs: These WAPs combine the functions of thin and fat APs. While a centralized controller will be used for tasks like bridging traffic forwarding between wired and wireless networks, most fat APs will handle Wi-Fi encryption at the AP level rather than waiting until the traffic gets back to the controller and may offer services like DHCP relay.

4.Router

The network hardware that routes packets between networks is known as a router. The internet connection that enables you to read this article as well as communication between several subnets connected to the same WAN are both made possible by Layer 3 devices. This is a helpful way to think of routers: They are the IP address-related network equipment.

5. NAS (Network attached storage)

The server used for file storage is known as a NAS. A NAS offers a central storage location within a LAN that can be utilized for things like shared file access and user data backup storage. In general, NAS devices offer an easy and economical approach to deliver network storage. The distinction between a NAS device and a general-purpose server has become increasingly hazy in recent years as NASes offer more sophisticated functionality appropriate for small and mid-sized workplaces.

6. Load balancing device

Client connections are distributed among various servers via load balancers. There are several software and hardware implementations of load balancers, just like there are for firewalls. The majority of the time, load balancers work at Layer 4 (filtering based on TCP or UDP traffic) or Layer 7. (filtering based on HTTP or DNS traffic).

The following are typical methods for load balancing:

·  Requests are simply forwarded to all servers in a round-robin fashion.

·  Round-robin is used in weighted round-robin, which uses “weights” to help determine how many connections to send to each server.

·  Least connections: A load balancing technique that gives priority to forwarding connections to the server that has the fewest connections.

·  Weighted least connections: Similar to weighted round-robin, this method enables the servers to be given “weights” that affect the load balancing process.

7. Reiterator

An easy Layer 1 device that rebroadcasts a signal is called a repeater. Signal boosters and repeaters are both technical terms. Wi-Fi, Ethernet, and other network connections all have repeaters, but they all essentially accomplish the same thing: receive a signal and send it again.

Simple Wi-Fi repeaters can cause a lot of network congestion, so use caution. A WAP is frequently a preferable option if you want to maximize performance.

8. Modem

A modem is a device that modulates and demodulates a signal to and from analog and digital, according to the conventional definition. When the internet was dial-up, modems were used to link local computer networks to analog telephone lines so that users could access the internet. The term “modem” today can refer to a wide range of gadgets that let you connect to a carrier’s network.

Popular models of modems include, for instance:

·  digital modems;

·  modems for cable;

·  mobile modems;

·  modems that use fiber;

·  an xDSL modem;

9.Gateway

There is no distinction between a gateway and a router in terms of hardware. Simply put, gateways are routers with a specialized function. Routers that serve as the default next hop are known as gateways. Packets are routed to the default gateway of a network when there is no other method to reach an IP address on that network. The packets are then forwarded by the default gateway to their subsequent “hop,” and the cycle continues until the destination is reached.

10. Hub

A hub is a basic Ethernet repeater that works at Layer 1 and allows several devices to be connected to the same Ethernet network. Because a hub, unlike a switch, does not divide collision domains, all ports on a network hub get the same traffic. As a result, hubs, which function similarly to WiFi repeaters, can be highly congested.

Pro tip: Hubs can cause severe network congestion by rebroadcasting data to all ports. If you have a use case for a hub, take into account an unmanaged switch instead, which will split collision domains.

11.Bridge

Network bridges were typically Layer 2 hardware with just two ports. When compared to hubs, they could minimize network congestion by dividing the network into several collision domains, breaking up collision domains like switches do.

However, depending on the context, the term “bridge” today can indicate a lot more than that classic connotation. The word “network bridge” can also mean:

·  a tool for Layer 2 VLAN connectivity;

·  an online switch;

·  a device that can join two networks together using various connection types, for as by joining a cable LAN and a WLAN.

Distance vector protocols;
Link state protocols;
Routing policy protocols;

Distance vector protocols are the simplest and most common. Protocols in this group include RIP IP, RIP IPX, AppleTalk, and Cisco IGRP. This type of protocol gets its name from the way information is exchanged. A router pulls the destination addresses and metrics from its routing table at regular intervals and puts this data into update messages that are sent out to neighbors. Neighboring routers check the received data against their own routing tables and make the necessary changes. They then send out their own update messages. In this way each router is informed about the routes of the whole network. While the algorithm is obviously simple, it is not completely reliable. It can only work effectively in small networks.

Link state protocols were first proposed in 1970 by Edsger Dijkstra. These protocols are much more complex than distance vector protocols. Instead of sending the contents of its routing tables to its neighbors, each router broadcasts a list of routers with which it has a direct connection and a list of the LANs directly connected to it. This information is part of the link state information. It is sent out in special messages. Furthermore, the router sends out messages only when the link state has changed or after a set time interval. Channel state protocols are difficult to implement and require a large amount of memory to store the channel state information. Examples of these protocols are OSPF, IS-IS, Nowell NLSP, and Cisco EIGRP.

According to Dijkstra, the network topology is represented as an undirected graph. A value is assigned to each edge. As the algorithm works, the sum of the scores for the edges converging at each node in the graph is calculated. This score is called the node label. When determining a path, the sum of labels on a possible path is calculated and the path with the smaller total label is chosen.

The third group of protocols includes routing policy (rules) protocols. These protocols most effectively solve the problem of delivering information to the recipient. This category of protocols is used for routing in the Internet, and allows operators to receive routing information from neighboring operators, based on special criteria. That is, a list of allowed routes (paths) is produced in the process of exchange. Routing policy algorithms are based on distance vector algorithms, but the routing information is based on a list of Internet operators. Examples of protocols in this category are BGP and EGP.

As a rule, for large and small organizations, there are a number of typical tasks to create computing and telephone networks, such as:

Creating a local network within an office or building
Combining a group of disparate branches into a single network
Creating a single center for switching computer and telephone networks
Increasing the security and control of the existing network
Integration of various data transmission channels into a single network (fiber channel, Ethernet, wi-fi, 3g, wimax).

Today the network solutions market is represented by a great variety of equipment, from usb-nethernet adapters to multitasking modular routers of enterprise level.

Kinds of active network equipment and their application for different tasks:
Layer 2 Network Switches or (switch) – devices used to combine computers within one network. Suitable for creating a local network in an office or combining several offices within one building.

Layer 3 switches – a special type of network equipment, capable of combining multiple different networks, requires specialized configuration, but in some cases, can replace such a device as a router, more expensive in cost and service. Suitable for combining multiple branches into a single network with different subnets in a stable network topology.

Routers are mostly enterprise-class devices capable of dynamically merging different networks, filtering, broadcasting and encrypting data transmitted over the network. Routers are the highest level devices used by Internet Service Providers and large organizations to consolidate and control a group of networks. Today, the market leader in this type of device is Cisco.

In addition to the expensive routers, there are some inexpensive specialized devices – Media Converters – for solving the problem of combining the different means of signal transmission. They can be used to convert optical data channel to digital and vice versa. The advantages of such devices are low cost, easy installation and use.

Access points for wireless networks (wi-fi, 3G) are separate inexpensive devices, which can be added to the existing wired network. Such a solution will be convenient when implementing a wireless network within the office and will save on installation costs when moving.

Patch panels provide connections between ports of active equipment and cables. Two types of cables are commonly used: shielded and unshielded twisted pair (STP and UTP). Depending on the type of network, telephone or computer outlets may be used.

Metal trays, cable channels, brackets and corrugated hoses are usually used for cable routing and protection, and clips are used to attach corrugated hoses. Accessories for cable channels are used for aesthetic reasons. They include: inner and outer corners, plugs, T-shaped branches and connecting bracket. In the case where you want to pull a bundle of cables used ties.

Cable
A structured cabling system begins with a cable. It is its basic and longest part. Two basic types of data cables are used in SCS: copper and fiber optic. The first type includes coaxial cable used in telecommunications, telephone cable, and the most common network cable – twisted pair (UTP). The second is fiber optic, the most advanced medium for transmitting information today.

Cable trays
Plastic (PVC) and metal trays and boxes protect data cable from damage, kinks, aggressive influence of the environment and access of strangers. On trunk lines and technical facilities are mainly used metal trays (galvanized, non-galvanized or stainless steel.), due to their high capacity.

Cable channels .
Inside the premises, where cable must be led to the end user, are used smaller plastic cable channels (boxes). Aesthetically, they are more attractive and fit well into the interior. Design and color can be chosen according to taste, from standard glossy white to any modern colors and textures.

Socket
The socket outlet is the end point to which the cable duct or cable concealed behind the wall leads. The socket is built into the wall and securely holds the cables that are connected to it. The standard RJ 45 (8P8C) computer jack and RJ 11 or RJ 12 for the telephone jack. The main function of the socket is to organize data cables in the room and provide a reliable connection of the patch cord.

Patch Cord
A patch cord is a patch cable that connects the end user to the network, or that is used to connect active network equipment. The type of patch cord corresponds to the type of cable used: twisted pair, telephone or optical. Requirements for the quality of its manufacture are very high. In order to crimp even a relatively simple twisted pair patch cord, you need a professional tool for cable stripping and crimping connectors. Optical patch cords are much more complicated. Therefore, it is better to use prefabricated factory patch cords. They are much stronger, tolerate more switching cycles, for which they are equipped with special “shanks”. “Tails” allow you to pull the patch cord out of the connector without the risk of pulling the cable itself out of the connector, or breaking any contact (as can happen with homemade counterparts). You can read more about why a factory patch cord is better than a homemade one here.

Connector
The connectors found at the ends of a patch cord are called connectors. The RJ 45 connector, a twisted pair (UTP) standard, is crimped according to a color chart (sometimes called a “pinout”). For its connection, a direct crimping scheme is mostly used, less often a reverse crimping scheme. Standard optical connectors include the following types: ST, SC, LC, FC and FDDI. They are mounted on the ends of an optical cable by chemical welding or mechanical fixation. To connect a thin coaxial cable, mainly VNC connectors are used. They are either soldered or crimped onto the end of the cable. The main types of coaxial connectors are: the T-connector, which connects the network cable to the network board; the barrel connector, which is used to splice two sections of cable; and the terminator (stub), which is installed at the ends of the cable.

Patch Panel
A patch panel is an essential element of SCS, streamlining it and facilitating its maintenance. Patch panels connect all cables from workstations, which are then connected to the ports of active network equipment. Patch cords are used for switching. A patch panel allows you to easily change specific cables without disturbing the lines that are next to them. Simply switch one or more patch cords on the panel. Standard patch panel has 12 or multiple of 12 connectors (ports) and is mounted in a 19-inch rack, but there are also wall-mounted panels.

Crimping tool
You can’t do professional crimping without professional tools. These include a knife for stripping the twisted pair (UTP) jacket, pliers for crimping connectors (crimper), and a tester – testing equipment that checks the twisted pair for proper functionality, or determines the cause of failure. Reliably crimped twisted pair cabling results in a loss-free connection, which has a positive effect on the operability of the entire system.

At exhibitions it is possible to obtain information about existing technologies, materials, equipment used, as well as specialists.

Equipment. Industry trade shows provide information on the major trends in networking equipment cabinets, including the equipment being used. Many companies present their new machines and even process lines. But most importantly – by purchasing equipment directly at the show, you can save significantly! Exhibited samples of machines and other equipment are sold cheaper than the market ones.

Technology. Industry shows allow you to purchase the most modern and advanced technologies that provide maximum productivity, reduced production cycles, reduced costs and much more. Like equipment, the presented materials are repeatedly tested and probably already effectively used. That is why before visiting the exhibition you should consider the possibility of purchasing technologies for the modernization of production.

Specialists. Recruitment can also be carried out at trade fairs. They are regularly visited by all kinds of specialists looking for new jobs. That is why it is much easier and faster to find qualified personnel at exhibitions, than using traditional methods, such as publishing vacancy announcements. Moreover, it is possible to poach specialists from competitors’ staff.

Market research. Exposures of the largest manufacturers of network equipment cabinets allow you to get information on supply and demand in this specialized segment. Thanks to the stands of leading manufacturers you can determine the most current trends in design, use of materials and attract the attention of potential buyers.

Competitor research. Any manufacturing company at an exhibition brings only the best of its range of products, materials and technologies. Therefore, a visit to such an event allows you to evaluate all the strengths of your competitors and develop a unique product that will attract the attention of potential customers.

Consumer research. Finding new customers and strengthening business relationships with regular customers is one of the most important tasks for any company participating in a trade show. Thoughtful analysis of the audience present at such an event will allow you to identify the most suitable counterparties, to whom you can later send a commercial proposal, or to form a target segment, to meet the needs of which will be aimed at future production.
