Oracle 10g vs. SQL Server

Don't believe the hype:


If you want to see a really bad and biased comparison of Oracle vs. SQL Server, check this:


Total Cost of Administration - Oracle 10g vs. SQL Server


Here is a good article comparing Oracle10g and SQL Server 2005 Yukon:


The Preface gives a great understanding of what this whitepaper compares:


The purpose of the following white paper is to provide a feature comparison between MSSQL 20051 and Oracle 10g. We will compare VLDB/OLTP related features and discuss issues with performance, utilities and replication. We will discuss several new features, which were developed by Microsoft in order to provide competitive functionality to its commercial rival Oracle database.At the same time we will discuss the changes from a Database Administrator stand point that were done to MSSQL 2005 release compared to previous releases. Since this topic is intended mostly to Database Administrators, we will not add information such as minimum requirements, supported platforms and max number of columns per table as redundant. We have never seen anyone purchase a database product only because it can hold up to 32k columns per table and not "just" 1024.


This paper includes the following topics for comparison of Oracle10g and SQL Server Yukon:


Major limitations of MSSQL prior to Yukon (such as MSSQL 2000)
Locking strategy
Online space reorganization and table/index partitioning
Clustering and high availability
Online data reorganization
Function based indexes via indexed computed column
