Build or Buy

Build or Buy. This is a major issue for all organizations. No one builds a data ware-house totally from scratch by in-house programming. There is no need to reinvent the wheel every time. A wide and rich range of third party tools and solutions are available, The real question is how much of your data marls should you build yourselves'? I low much of these may be composed of ready-made solutions? What type of mix and match must be done'?

In a data warehouse, there is a large range of functions. Do you want to write more house programs for data extraction and data transformation? Do you want to use in-house programs for loading the data warehouse storage"! Do want to use vendor tools completely for information delivery'? You retain control over the functions wherever you use in-house software. On the, other hand, the buy option could lead to quick implementation if managed effectively.

The wary of the marts-in-the-box or the 5 minute-data-marts, There are no silver bullets out there. The bottom line is to do your homework and find the proper balance between in-house and vendor software. Do this at the planning stage itself.
