This is a complete multipart blog article series, in which I am going to explain you about the concepts of DBMS (Database Management System). This article series is divided into several modules and each module contains 10 parts.
In this article you will get to know that what database system is, and types of database system in details.
Database System : Every organization whether private or government, have a big chunk of data and they have to maintain the data, in order to use it in future or for any other task like statics etc. To store this huge chunk of data every organization has their own database system. Database system are mainly divided into two categories Database and DBMS
Database : If I have to explain you the meaning of database in simplest manner then I will say that Database is a collection of related data. Technically the database is future divided into three categories structured, semi-structures and unstructured. We will discuss about structured and unstructured data because they are main and mostly concerned.
Structured Database : Structured database means that the database in which we can store data in a particular shape or structure. It is done with the help of a concept that is known as RDBMS (Relational Database Management System). We store the structured data in the form of relation/table.

Unstructured Database : Unstructured database means that the database in which we do not store the data in any structured format.
- Examples : Webpages.

DBMS : Now as we had stored the data in a structured manner, then we also want to perform some operations on that data in order to use it, these operations can be write, delete or update. So, in order to perform these operations DBMS comes into play. DBMS provides us the way to manage the data by performing different types of operations on it.
- Different companies had made different-different DBMS the most common examples of DBMS are SQL Server, Oracle, MySql and DB2.
Note : At present almost 90% of the data is stored in unstructured form.
