I want to learn a database server, SQL server 2012 or Oracle 11g . I surf in the internet to compare SQL server and Oracle for spatial data and found good websites such as gisboston.it was very interesting for me but i want to compare oracle and sql server about job opportunity in GIS. which one is better to find a good job? which one is better to manage spatial data ?
I have administered SDE and designed enterprise GIS in both Oracle and SQL Server. 17 years ago when I got my Oracle Master Certificate, I used to consider SQL Server nothing more than a beefed up Access database. Things have changed.
There are new capabilities in SQL Server which have had such a fundamental impact on geodatabase management that has forced even Esri to adopt SQL Server for its standards. Oracle spatial was released with Oracle 7. Since then, no one else, neither Esri, MapInfo, SmallWorld, Autodesk nor Google has adopted Oracle spatial. SQL Server was released April 2012.
Let me recommend you to take a look at this review: sql-server-vs-oracle-bdms-comparison.
