MySQL Installation Guide | What is Database Management System? | Realcode4you


1. INTRODUCTION TO DATABASE MANAGEMENT SYSTEM

A database is a collection of data stored in a format that can be easily accessed. To manage our databases, we use a software application called database management system, or, DBMS. We connect to a DBMS and give it instructions for querying or modifying data. The DMBS will execute our instructions and send the results back. Now we have several database management systems out there, and these are classified into two categories, relational and non-relational, also called NoSQL.


In relational databases, we store data in tables that are linked to each other using relationships. That's why we call these databases relational databases, each table stores data about a specific type of object, like customer product, order, and so on. SQL or SQUEL is the language that we use to work with these relational database management systems. We use SQL to query or modify our data. Now, there are many different relational database management systems out there, some of the most popular ones are MySQL, Microsoft SQL Server, Oracle Database, MS Access, and plenty more.



Each database management system has a different flavor of SQL. But all these implementations are very similar and are based on the standard SQL specification. So, most of the SQL code that you will learn will work with any database management system. In this course, we'll be using MySQL, which is the most popular open-source database in the world.


what about non-relational databases?

In non-relational databases, we don't have tables or relationships, these databases are different from relational databases. What you need to know is that non-relational database systems don't understand SQL. They have their own query language.


So, we use SQL to work with relational database management systems.
