A Relational Database Management System is a collection of program that allows to create, update, searching and interact with a relational database. Relational Database Management System accesses the database using SQL or MySQL language. RDBMS is relational because of the fact that the qualities within each table are related to one another. Tables are also related to other tables.

Look at these properties
Data Definition
Data definition language (DDL) is data structures that are going to be using in the database. Data definition is going to store data about your tables and collection tables, some people called Metadata so Metadata is data about data. DDL is going to create rules and things like you can’t store text called a string inside of a number field. If you call the number you are going to build up the word that number field the database is not going to allow, it will throw an error. You can say that a field required value, so you need to provide value and there is a number of different constraints that we can set up.
Data Manipulation
When we go through and manipulate the data in the relational database management systems to make sure that what you are doing is going to add here to the rules. If you try to write outside the lines with an update or if you try to change something or if you try to delete something then it will throw an error. Data manipulation is just inserted update and deletes.
Data Retrieval
Relational database management systems are going to dismiss the ideal way to retrieve data out of the database. When you want to join out those tables from one table to another table that also has billions of zeros and if you do that incorrectly your reporting go from seconds to hours. In relational management system, you can retrieve data using select statement.
Administration
We will get user accounts on the framework and these user accounts will have security roles and these roles are going to control what that client can see. So systems have a very powerful account that can do everything. The relational database management system is going to apply those security roles of who can see what who can update what who can delete and this account is administrator accounts. You can use system administration to say how to store your data and how the system to lay it out and you do this. The administrator is going to get into backups and auditing.
