Things to Consider Meta Data Repository Usage Who will be using the meta data in the meta data repository? What standards do we have in place for its use? What standards do we need to develop? Do we already have a meta data repository? If not, will we license (buy) one or build one? Will this meta data repository support only the BI decision-support environment, or will it be used for all systems throughout the organization? How will we know if we are using the meta data repository effectively? Meta Model Requirements Do we need to create a meta model for the meta data repository, or do we already have one? If we have one, what meta data objects do we need to add to it? Which meta data repository products support our meta model? Are these meta data repository products extendable? Meta Data Repository Security What type of security will we need for the meta data repository? Who will be authorized to enter and maintain the meta data? Will everyone be authorized to access any meta data at any time? Meta Data Capture What types of business meta data do we need to capture? Will we be using a computer-aided software engineering (CASE) tool to capture the business meta data? What type of technical meta data do we need to capture? Will we be capturing technical meta data in the extract/transform/load (ETL), online analytical processing (OLAP), and other access and analysis tools? How will we extract the meta data from these tools and migrate it to the meta data repository? Who is responsible for migrating it? Who will connect the business meta data from the CASE tool to the technical meta data from the ETL, OLAP, and other tools? Meta Data Delivery How will meta data be displayed? How will it be accessed? Will we have a Web interface to the meta data repository? Will we need to produce meta data reports? What types of reports ? How will these reports be distributed? Will there be a help function (online tutorial)? Will the help function be context sensitive? Staffing Do we already have a meta data administrator? If not, do we have a data administrator with technical skills who can perform the functions of a meta data administrator? Will we have to hire more meta data administrators? How will meta data responsibilities be divided among data administrators and meta data administrators? |
