Conclusion • SQL Server 2000 is the least expensive of the three, however, it can only run on the Windows environment. • Oracle 9 i is the most functional mainly because it can be run on any operating system, it also provide a serials application to meet special need (e. g Oracle Finance, Human Resource). Oracle 9 i is a fully object-oriented database, it can model any object in the real world, and finally it has most of the market share. • DB 2 UDB 7 has just move from main frame to Client/Server based database market. Similar to Oracle 9 i, it can be run on any operating system, and may potentially gain more market share later. • Choosing a Database software depends on the consistency of the organizational software system and the functions you need. However, migrating the data to a new system may be relatively expensive. Existing system may not meet your future development need.
