SQL Server 2000 only works on Windows-based platforms, including Windows 9x, Windows NT, Windows 2000 and Windows CE.
In comparison with SQL Server 2000, Oracle 9i Database supports all known platforms, including Windows-based platforms, AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Sun Solaris and so on.
1.Oracle runs on many platforms, SQL on Windows only
2. Oracle includes IFS (Internet File System), Java integration, SQL is more of a pure database
3. Oracle requires client install and setup (Not difficult, but very UNIX-like for Windows users)
4. SQL is #1 in Cost/Performance and overall Performance, although Oracle will refute that
5. Replication is much easier in SQL (I have been at clients where even the Oracle consultant couldn't get it working w/oracle)
6. Failover support in SQL is much, much easier
7. JDBC support is much better in Oracle, although Microsoft is working on it
8. ODBC support in both
9. SQL is ANSI-SQL '92 compliant, making it easier to convert to another ANSI compliant database, theoretically anyway (truth is every database has proprietary extensions). Oracle is generally more proprietary and their main goal is to keep their customers locked-in.
10. SQL natively supports ODBC, OLEDB, XML, XML Query, XML updates. Oracle natively supports proprietary connections, JDBC. Not sure about XML support though.
11. SQL Server is much easier to administrate, with GUI and command- line tools. Most of Oracle is command-line (Back in SQL 6.5 days I had a customer who was so proud that after a day's worth of work he had managed to script his database. I showed him how it was a 3 click operation in SQL ;-)
12. Oracle requires add-ons for transaction monitors, failover, etc. SQL has COM+, uses NT clustering and generally has everything built-in
13. SQL Analysis Services is included (A very powerful OLAP server). For Oracle it is a separate purchase.
14. Oracle will be used especially in large database. But if we use sql server in such a environment, the data processing will become very slower. Oracle database very closely supports Java rather than Sql server.
15. Oracle 7 was RDBMS, i.e it was a relation database and the one's after that i.e. 8 onwards Oracle introduced the concept of OODBMS. Which stands for Object Oriented Database Management Systems. With every major release Oracle has initiated a lot of changes for the better. Like
a. (1) Getting PL/SQL closer to ANSI SQL standards
b. (2) Automatic Management of Undo from 9i onwards
c. (3) Introduction of special Grouping operators for queries
d. (4) ISQL env for easier query processing
e. (5) RAC (I dunno much about it)
f. (6) AS(Application Server, integrated into the database)
16. SQL server GUI is easy to work. SQL serever is easy to maintain. Orcal data procssing is very good compared to SQL server
