Business intelligence need not wait for legacy conversion
Even if it takes more effort to deal with legacy system, one should proceed with the Business Intelligence initiatives, if it makes business case.

Every organization has a road-map of modernizing legacy systems to new next generation platform to achieve multiple objectives of cost, efficiency and business value. Many a times, these legacy systems, carrying critical data are by-passed for Business Intelligence priorities, as they need more effort for ETL and it is felt that once they are migrated (say to SAP kind of systems having their own business warehouse), many of the Business Intelligence requirements will be met by leveraging the existing Business Intelligence framework (For example Business objects sitting on top of SAP Database or business warehouse).

This is a logical argument for an organization, which is in the initial stages of Data and Information management deployments. However, this should not be taken as a hard and fast rule, if:

  • You have already got some expertise and experience in deployment.
  • The legacy system supports a critical information requirement theme.

By involving the Legacy system as a source, will also help you to migrate the data to next generation system (say ORACLE ERP), as and when the legacy system is moved to the new platform.
