Database-SQL-RDBMS HOW-TO document for Linux (PostgreSQL Object Relational Database System): Conclusion

28. Conclusion

After researching all the available databases which are free and source code is available, it was found that ONLY PostgreSQL is the MOST mature, most widely used and robust RDBMS SQL free database (object relational) in the world.

PostgreSQL is very appealing since lot of work had already been done. It has ODBC and JDBC drivers, using these it is possible to write applications independent of the databases. The applications written in PostgreSQL using ODBC, JDBC drivers are easily portable to other databases like Oracle, Sybase and Informix and vice versa.

You may ask "But why PostgreSQL ?" The answer is, since it takes lot more time to develop a database system from scratch, it makes sense to pick up a database system which satisfies the following conditions -

A database system

Whose source code is available - Must be a 'Open Source Code' system
Has no license strings, no ownership strings attached to it
Which can be distributed on internet
Which had been on development for several years.
Which satisfies standards like ISO/ANSI SQL 92 (and SQL 89)
Which can satisfy future needs like SQL 3 (SQL 98)
Which has advanced capabilities

And it just happens to be 'PostgreSQL' which satisfies all these conditions and is an appropriate software for this situation. You may say 'PostgreSQL' is a very strange name. But my argument is - why change the name. This world is stuck with "PostgreSQL" forever!!
