Relational Database

Relational database refers to the database that has a set of different table of different data items. A database can be defined as the application that is useful to store and retrieve data from various sources rapidly. Another definition of relational database is the process in which data is stored in the application or database.

Each table schema should be identified by a group of column or a single column that is known as primary key. A relationship is possible there that should be established between each column of the table an each row in the table. The relational model also offers a number of different levels of refinement of the organization of table, and its reorganization is known as database normalization. The relational database is also known as database management system. The relational database was proposed by Edgar Codd in the year 1970. Edgar Codd belonged to IBM's research laboratory. Relational database has now become the predominant choice of various different organizations because of its assistance. Hierarchical data model and network model are other database that is being used as the alternative for relational database. A number of security and government organizations are using relational database for various purposes. The major purpose is regarding the collection of data, storage, security, deletion, retrieval, and integrity of the data (Bornea, Dolby, Kementsietsidis, Srinivas, Dantressangle, Udrea & Bhattacharjee, 2013).

There are zero percent chances of errors in this database, and it is considered as the major benefit of this database. All of these benefits have a direct impact over the importance of relational database (Bornea, Dolby, Kementsietsidis, Srinivas, Dantressangle, Udrea & ...
