Let’s start from the absolute basics so that any term/topic doesn’t feel alien to you. So as the topic reads, RDBMS that stands for Relational Database Management System, it can be segmented into 2 different phases.
One being the Relational part and other one being the DBMS part. As the ‘database’ is already explained in the earlier topic, we will jump directly into the meaning of Relational Database.
A relational database is an arrangement of formally depicted tables from which information can be reassembled in a wide range of routes without revamping the database tables. The standard client and application programming interface (API) of a social database is the Structured Query Language (SQL).
SQL articulations are utilized both for intuitive questions for data from a social database and for get-together information for reports.
As we have the prerequisite knowledge of the term ‘Relational Database’, we may go to the meaning of Relational Database Management System (RDBMS) that we will primarily focus on this course.
A Relational Database Management System (RDBMS) is an accumulation of projects and abilities that empower IT groups and others to make, refresh, manage and generally connect with a relational database.
Most business RDBMSes utilize Structured Query Language (SQL) as we already discussed, to get to the database, despite the fact that SQL was imagined after the underlying advancement of the Relational model and isn’t essential for its utilization.
The basic differences between DBMS and RDBMS are given as follows:
- DBMS stores information as file systems and hence extracting them for comparison is difficult whereas RDBMS uses the system of tables for storing data and hence the relation between them is quite visible.
- DBMS doesn’t provide any security to the data that is stored but RDBMS provides security to the data that will be more clear when you go through it.
Now, the obvious question that arises in your mind would be the relation of the term SQL with RDBMS. Structured Query Language (SQL) is the best and most common way to implement RDBMS and data access.
The language mainly comprises of data manipulation language (DML) and data definition language (DDL) statements.
Here is one example of how a typical table looks:
