4. What is Metadata? Data About Data

5. Defining of Metadata Anne Marie Smith: It is the collection of information about the data collected in an application or database. Examples of meta data include: definition of the data element, business names of the element, systems abbreviations for that element, the data type (alphanumeric, decimal, etc...) and size of the element, source location, etc... All of these pieces of meta data are of interest to various members of the organization's community; some are of interest only to certain IS staff members, while other pieces would be very useful for business people attempting to navigate through the corporate Data Warehouse.

6. Defining Metadata Rob Seiner: Meta data is not really new. It was around long before you and I arrived in this industry. Meta data will be around long after we go to that great repository in the sky. But it was not until the past ten years, maybe much less, that the importance of managing meta data became apparent. This increase in importance has been a result of companies integrating the vast number of information systems and databases, creating decision support environments, and paying attention to managing data as a valued corporate asset.

7. Defining Metadata Metadata is data that describes the definition, control, usage and treatment of data within a system, application or environment.

8. What is Metadata? Metadata is everywhere. –It helps you understand the world around you. –Without it you are lost –Metadata exists without us use of a computer

19. Metadata Challenges Repositories have a tough time keeping up to date Maintenance Tools do not integrate well The masses do not understand metadata Resources Cost
