Recommendations for a language for retrieving information from different datasources (Web based)
My background is primarily networking so please keep it simple and broad for now :) I am needing some steering as to the best language(s) and methodologies to utilise for the following scenario (I will most likely oversee development of the project, but could possibly be landed with the programming job too):
We have an inhouse SQL Server database that records our clients and their purchases. Much of it is tailored to property details (our main investment 'product' ATM), but this will be expanding to possibly include shares and superannuation.
This info needs to be made available to clients online (securely of course, so will need to manage logons) AND also provide a facility to report on the current value of their investment by interrogating other websites or sources (some may be SQL, others might be using a querying tool provided by the website itself, obviously all these sources are subject to change, so adaptation or at least easy modification of data source(s) and interrogation will need to be a core component).
I suspect this is best done as a two stage process, firstly developing an application to handle the interrogation and reporting of the different datasources, and secondly (more web based) the customer portal and security etc. but have never attempted this kind of project before.
I have also posted this q to web development, but thought the information retrieval app would perhaps be better answered here. I'm really groping in the dark (but not as much fun as usual) so any candle is appreciated.
