Since the BI infrastructure architect has the ultimate architectural responsibility over the BI decision-support environment as a whole, he or she needs to review all design activities. If a meta data repository is licensed, the BI infrastructure architect may participate in preparing the evaluation criteria and in deciding the weighting factors for the criteria. He or she will also be involved in the final product selection.
Data administrator
The data administrator will collaborate with the meta data administrator on the meta data requirements and help the meta data administrator with the data-modeling activities. The data administrator can also be an effective liaison between the meta data administrator, the subject matter expert, and the business representative when meta data requirements need to be verified or design decisions need to be reviewed or communicated.
Meta data administrator
The meta data administrator holds the primary responsibility over the meta data and the meta data repository. If the meta data repository is built in-house, he or she is responsible for designing and developing it. If a meta data repository is licensed, he or she is responsible for installing, testing, enhancing, and maintaining it. The meta data administrator is also responsible for designing the access interfaces as well as the migration programs to the DBMS, CASE tool, ETL tool, OLAP tool, and other tools.
