9 1. Why?2. SMW? 3. The PoC4. The Unexpected5. Wrap Up Business Requirements 1.Allows business users / end users to gain the required insight into what the data and reports they are looking at means 2.Makes data available and visible to others 3.Creates a searchable set of information about the firm’s data. This allows data developers and users to search for existing data and avoid data duplication. 4.Provides a platform for sharing and publicizing data. This reduces the workload of developers (interfaces, reports, etc.) and users and increases efficiency. 5.Quality control, data restrictions and uses can be applied to the entire data set. 6.Metadata documentation transcends people and time. Staff turnover and balancing of multiple projects can be mitigated with metadata, providing data permanence and the documentation of institutional knowledge. Value of Meta Data & Meta Data Tool

MDM could stand for Master Data Management or Meta Data Management… coincidence? “Lets go get all the key pieces of data and put them in one place, which is really more of an enterprise data warehouse but master data management then says… it’s almost a map… here is what each of those data fields are, here is how you can find them, here is what they mean, here is where they came from.” Blake Johnson Consulting Professor Stanford University “The Truth and Power of Master Data Management” (Teradata) http://www.youtube.com/watch?feature=player_embedded&v=p6VHpIlDfu4#!
