Database Systems Setup: PostgreSQL , MySQL, MS SQL Server

Database Systems or DBMS is software that caters to the collection of electronic and digital records to extract useful information and store that information is known as Database Systems/ Database Management Systems or DBMS. The purpose of a standard database is to store and retrieve data. Databases, such as Standard Relational Databases, are specifically designed to store and process structured data.

Generally, Databases have a table to store data, they use Structured Query Language (SQL) to access the data from these tables. Databases and Database Systems play a vital role in processing hard, fast and diverse datasets. Without a Database Management System, businesses won’t receive valuable insights and deep analytics.

In the Database environment, data is accessed, modified, controlled, and then presented into a well-organized form, allowing the business corporations to execute multiple data-processing operations. The data is usually organized in the form of rows and columns to minimize the workload pressure and achieve accurate results instantly.

Different types of data that can be stored, processed, or retrieved in Database Management System include numerical, time series, textual and binary data.

PostgreSQL is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads.

MySQL is an open-source relational database management system. MySQL is a tool used to manage databases and servers, so while it’s not a database, it’s widely used in relation to managing and organising data in databases.

Microsoft SQL Server is a relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications—which may run either on the same computer or on another computer across a network.
