I recently read with interest an article in the Microsoft Architect Journal on so-called Service-Oriented Business Intelligence or, as the article’s authors call it, “SoBI.” The article was well-intentioned but confusing. What it confirmed to me is that plenty of experienced IT professionals are struggling to reconcile Service Oriented Architecture (SOA) concepts with business intelligence.
SOA is certainly a valuable tool in the architecture and development toolbox; however, I think it’s only fair to keep SOA in perspective. It’s an evolutionary technology in IT that has numerous benefits to developer productivity and application connectivity. I’m not sure that injecting SOA into a data warehouse environment or framework will do anything more than freshen a few low-level building blocks that have been neglected in some data warehouse environments. I’m certainly not challenging the value of SOA; I’m just trying to put in perspective to those folks that are focused on data warehouse and business intelligence activities.
The idea around SOA is to create services (or functions, procedures, etc.) that can be used by other systems. The idea is simple: build once, use many times. This ensures that important (and possibly complicated) application processes can be used by numerous disparate applications. It’s like an application processing supply chain: let the most efficient resource build a service and provide to everyone else for use. SOA provides a framework for allowing multiple applications access to common, well-defined services. These services can contain code and/or data.
The question for most data warehouse environment’s isn’t whether SOA can improve (or benefit) the data warehouse; it’s understanding how SOA can benefit a data warehouse.
We’ve got lots of clients leveraging SOA to support their data warehouse. They’ve learned they can leverage SOA techniques and coding to deliver standardized data cleansing and data validation to a range of business applications. They have also upgraded the operational system data extraction code to leverage SOA which allowed other application systems (or data marts) to reuse their code.

After all, cost is key here as many cannot afford INR 4 million [in India] tools from Cognos, et al.
So I expect to see lots of stuff specially using .NET [SQL server already has so much in it SSIS, SSAS, SSRS] and JAVA / Oracle and other technologies.
PHP probably will be used for a lot of web analytics BI.
