SAP Information Steward is a data quality tool. We use the solution to build data quality rules to detect issues in source systems. The solution has many components, the data inside that is being used for data quality and data that is being used for the business glossary and metadata management.
Information Steward has a component called, 'Metapedia' that describes technical fields in business terms. It is equivalent to a business glossary in other systems.
When we see a business intelligence report, we want to be sure that the figures we are seeing are consistent with the transformation. We want to be able to see where the number is coming from. For example, we want to know if the data is from an ERP and is being transformed by an ETL and then loaded into a warehouse. Using metadata management in the Information Steward, we can see all of these steps.
SAP Information Steward also has a cleansing package that helps in the matching process in data services. For example, the name of a person. In many systems, the same person can have their name displayed in many different ways. In one system an individual could be Bob Smith, in another system it could be Bobby Smith and another could show Robert Smith. The cleansing package will try to get all of these synonyms in one place and link it to a standard one. By applying these cleansing packages in data services, we are able to consolidate all the different terms into just one.
