Hi (updated due to weird formatting issue from mobile device :( sorry)
I have three+ data sources.
There are duplicates in some of the sources (ie there is the same customer in two or more sets) but each source COULD bring more data as there is no single source of truth.
Is SSRS the right tool for this or do I need to do it in fancy SQL (or worse a program!)?
I had something like this in mind:
+ The artificial "good" record here (no nulls) but also need to be able to "prioritize" certain sets (if there are no nulls in its data)
- Source 1 here
- Ssource 2 here notnull (perhaps)
- Source 3 here nulls (or not)
eg:
+ CustomerID01, Mr, James, LastName, 123 AddressStreet, MySuburb, ??Yesterday??(date)
- CustomerID01, null, null, LastName, 123 Address St, MySuburb, LastWeek(date)
- CustomerID01, Mr, J, LastName, 123 Address St, MySuburb, ThisWeek(date)
- null, Mr, James, LastName, 123 Address Street, MSuburb, Yesterday(date)
I need these three to be merged (yes even without the customer ID) visually but the user be able to "question" the results by expanding the "sources" from the artificially created record (next to the +).
***Biggest problem that I omitted in the first post (again sorry), is that the sources reside on separate servers that are all reachable by SSRS but don't have linked servers setup, so you can't query from a single SOURCE...
(this may not be a deal breaker, but I was trying to avoid another point of maintenance since the SSRS connections would likely need to be different to the linked servers (haven't setup linked servers for a long while)
