Dr. Edgar F. Codd in 1970 in his book titled "A Relational Model of Data for Large Shared Data-banks".
The two major commercial classes of database are; relational and non-relational. Example of non-relational databases include Informix c-isam and dbisam. The main relational databases are; MS SQL Server, Sybase, Oracle, Progress, mySQL.
A Relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as introduced by E. F. Codd. Most popular commercial and open source databases currently in use are based on the relational model. A short definition of an RDBMS may be a DBMS in which data is stored in the form of tables and the relationship among the data is also stored in the form of tables.
SQL is not software in the sense that you can run it as a stand-alone program. SQL stands for Structured Query Language and is that a language for querying relational databases. It was originally developed at IBM and became the de facto standard relational database query language in the 1980s.In order to execute (run) SQL queries against a database, you need an implementation that can interpret the SQL statement and return the data as specified from your data store. Also, Open Access as a concept does not apply to software. See related links for details.
A database is something that stores data. Using tools called Database Management Systems(like Oracle, Informix, Sybase, DB2), you can create, view, modify, and delete databases. Databases can be -Relational -Object Oriented -Object Relational Relational database stores data in tables(called realtions). These tables are related to each other.Just like in our family, our relations are related with each other. In Object Oriented Databases, the information is stored in the form of Objects as in Object Oriented Programming.OODBMS makes database objects appear as programming language objects in one or more porgramming languages. Object relational databases combine the features of both Object Oriented as well as Relational databases. Here you can not only store simple data like text in relational, but you can also store complex objects like images, audio and video in tables.
RBMBS stands for "relational database management systems" A very basic concept is: a system for collectingpieces of information about a person or entity or even a product that allows for a sensible and or logical presentation at will, different forms or structure for a particular purpose. For example a telephone directory of names and individuals listing is a relational database. The phone directory like the white pages that we normally use is one form ofa database.Another form of the same database thatis used by an emergency agency or police department, (the so called reverse directory) is a database of the sameinformation but listed with the number first instead of the name of the person.
A relational database is a type of database design. Oracle is a brand of database. You can create a relational database using Oracle. You can also create relational databases using other database applications.
In the context of a relational database, a file is commonly referred to as a table. A table is structured in rows and columns to store related data in a database system. Each table represents a specific entity or concept within the database.
Oracle is relational DataBase
The best relational database is Valentina Studio.
A relational database is needed for many things. A relational database is known for collecting and organizing various data items into different charts and pictures.
Dr. Edgar F. Codd is often referred to as the father of the relational model for database management. He introduced the concept in his influential paper in 1970, which laid the foundation for modern relational databases.

Relational database: Relational database means a collection data stored in different tables and each table are linked together by using primary key and foreign key. In relational database, data can be accessed from one table to another without reorganising the required table. The relational database was invented by E. F. Codd at IBM in 1970.
A relational database stores data in the form of TABLES.
Tables are the basic building blocks of a relational database.
