Do you need data retrieving from a legacy database and can’t find anybody who knows anything about it ?
Do you have an existing database where the performance is not what it should be ?
Do you need a database designing ? One that will run well in the real world and not designed purely according to academic theory ?
The database is a fundamental part of almost every business. Behind every corporate system lies a database of some description. Maybe you need someone to analyse, audit or report from your database ?
