Good data governance and master data management processes and tools are essential for any data integration project to reach its full potential.
Many database systems are plagued by duplicates and junk data because there are no processes or tools in place to ensure data quality on an ongoing basis. In addition, it is often the case that different departments in an organization are operating from different datasets for the same entity, which can result in situations that are embarrassing or worse. For example, Marketing may be using a system that is not fully integrated with other back office systems so they send a misinformed email to an important client. The concept of master data management is intended to ensure that all parts of an organization are operating from the same data set when they deal with a particular entity (like a client). In other words, everyone is working from a "single version of the truth."
Groove designs systems with these things in mind, and we can put in place systems and recommend processes that will help you keep your data clean and integral.
