Creator of Database Concept

Invention and creation always done by IBM for SQL or RDBMS Concept. If you study Structure Query Language then you can get more idea about invention of SQL done by IBM. Dr. E. Codd invented RDBMS Concept. And after different kind of database was developed and came in to global market like mySQL, PostgreSQL, Oracle, MSSQL, etc. But main thing is RDBMS concept. Relational Database is widely accepted in global market. Because most of of business requirements are fulfilled by this rdbms concept.

Due to these all reasons, IBM is always ahead in database invention and conceptual deployment. But unfortunately Oracle is ahead from IBM in database domain.

In past Oracle didn't have own plateform like operating system and storage plateform. But Oracle captured global market in database domain. Now after took over of Sun, Oracle has own operating system and storage plateform too. As per my thinking, Oracle would be capturing more market share than others in future.

Unfortunately, after certain important inventions in database field, IBM DB2 is not able to capture good market in global technology world. I tried to study and understand IBM DB2 database sometime back due to client's requirement of migration from DB2 to Oracle. I surprised to see so many good features DB2 have. As Database administrator and to perform good database administration we need to understand all database concepts.

For obtaining knowledge of comparision of IBM DB2 and Oracle, you can get good idea and concept from DB2 and Oracle Server comparison.

During remote database administration, database dba has to work hard and known with every concept and features of all kind of databases.
