SSRS online training

SSRS is a wonderful tool for quickly retrieving data from many different data sources and presenting the data to the user at a run-time decided format. One area where SSRS often falls short is when the underlying data needs to come from several different sources. Perhaps we want to retrieve data from the General Ledger which is in Oracle, and join that against employees which are listed in SQL Server to display in a table. Many times, when this happens, we end up with two disconnected data sets and are unable to join them without the use of a linked server.
