Question: What is difference between oracle and sqlserver ?

Answer: 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.

ORACLE

Oracle provides password complexity enforcement rule.

Connect with one Schema and can work with other schema.

Oracle implemented the row versioning on the DB block level.

Oracle metadata is managed in the same manner as table data.
So during data querying most of online DDL statements on the table can be performed simultaneously.

Starting from Oracle 9i the configuration of ROLLBACK SEGMENTS is automatic.

Oracle is well rich with Index Options.

Oracle provides Automatic Storage Management (ASM), which assists with RAC/Grid based cluster deployment.

Oracle provides proprietary cluster file system on Linux and Windows platforms that helps in avoiding the use of raw devices.

Oracle provides Materialized Views for performance improvements of Stored Data with multiple Tables.

Oracle has more recovery options for corrupted database, redo log or datafile than MSSQL.

MS SQL

Microsoft implemented row level lock based on each single row.

SQL Server
all DDL operations that are currently running on tables belong to database "Snapshot Isolation". "Snapshot Isolation" queries are prohibited.

SQL requires a complex setup of ROLLBACK Segments and Transaction Level use on it.

SQL has just BTREE Index while compare to Oracle.

SQL has limitations using Materialized Views. Source: CoolInterview.com
