A database is a collection of data, which is organized into files called tables. These tables provide a systematic way of accessing, managing, and updating data. A relational database is one that contains multiple tables of data that relate to each other through special key fields. Relational databases are far more flexible (though harder to design and maintain) than what are known as flat file databases, which contain a single table of data.
To understand the advantages of a relational database, imagine the needs of two small companies that take customer orders for their products. Company A uses a flat file database with a single table named orders to record orders they receive, while Company B uses a relational database with two tables: orders and customers.
When a customer places an order with Company A, a new record (or row) in the table orders is created. Because Company A has only one table of data, all the information pertaining to that order must be put into a single record. This means that the customer's general information, such as name and address, is stored in the same record as the order information, such as product description, quantity, and price. If customers place more than one order, their general information will need to be re-entered and thus duplicated for each order they place.
Whenever there is duplicate data, as in the case above, many inconsistencies may arise when users try to query the database. Additionally, a customer's change of address would require the database manager to find all records in orders that the customer placed, and change the address data for each one.
Company B is much better off with its relational database. Each of its customers has one and only one record of general information stored in the table customers. Each customer's record is identified by a unique customer code which will serve as the relational key. When a customer orders from Company B, the record in orders need contain only a reference to the customer's code, because all of the customer's general information is already stored in customers.
This approach to entering data solves the problems of duplicate data and making changes to customer information. The database manager need change only one record in customers if someone changes addresses.

What is the advantage of database?
Greater data integrity and independence from applications programs. Improved data access to users through use of host and query languages. Improved data security. Reduced data entry, storage, and retrieval costs.
Which of these are RDBMS?
Most well known DBMS applications fall into the RDBMS category. Examples include Oracle Database, MySQL, Microsoft SQL Server, and IBM DB2. Some of these programs support non-relational databases, but they are primarily used for relational database management.

Why RDBMS is important for the organization?
The use of an RDBMS can be beneficial to most organizations; the systematic view of raw data helps companies better understand and execute the information while enhancing the decision-making process. The use of tables to store data also improves the security of information stored in the databases.
What are the uses of RDBMS?
The software used to store, manage, query, and retrieve data stored in a relational database is called a relational database management system (RDBMS). The RDBMS provides an interface between users and applications and the database, as well as administrative functions for managing data storage, access, and performance.
