The Meta Data Coalition, a group of database and data warehouse vendors established in 1995, developed a standard for defining metadata called the Metadata Interchange Specification (MDIS). They also created Microsoft’s Open Information Model (OIM), which was eventually merged with MDIS. In 2000, the Meta Data Coalition and the Object Management Group (OMG) joined forces to create a single standard for representing metadata in data warehouses. OMG has since attempted to integrate OIM into its Common Warehouse Model (CWM) to achieve this goal.
FAQ: The Meta Data Coalition
What is the Meta Data Coalition?
The Meta Data Coalition is an association of database and data warehouse vendors that was founded in 1995. Its main goal is to create a single standard for representing meta-data in data warehouses.
What is meta-data?
Meta-data is data that describes other data. It provides information about a particular data set, such as its format, structure, and content. In the context of data warehousing, meta-data describes the data that is stored in a warehouse.
What is the Metadata Interchange Specification?
The Metadata Interchange Specification (MDIS) is a standard that was introduced by the Meta Data Coalition in 1996. It defines a common format for exchanging meta-data between different systems and platforms.
WHAT is the Meta Data Coalition?
The Meta Data Coalition is an organization that was created to address the need for a standardized approach to managing meta-data in data warehousing environments. Since its inception in 1995, the coalition has worked to develop common standards that enable vendors and users to exchange meta-data in a consistent and meaningful way.
One of the key achievements of the Meta Data Coalition was the creation of the Metadata Interchange Specification (MDIS). This standard provided a common framework for exchanging meta-data between different systems and platforms, which made it easier for organizations to implement data warehousing solutions.
In addition to the MDIS, the Meta Data Coalition also developed Microsoft’s Open Information Model (OIM) in 1996. This model provided a standardized way to represent the structure and content of a data warehouse.
Over time, the coalition began to collaborate with other organizations in the industry, including the Object Management Group (OMG). In 2000, the Meta Data Coalition and the OMG merged their efforts to create a single, comprehensive standard for representing meta-data in data warehousing.
Today, the work of the Meta Data Coalition lives on through the Common Warehouse Model (CWM), which is maintained by the OMG. The CWM is a comprehensive model that provides a standardized approach to managing meta-data in data warehousing environments. It includes both the OIM and the MDIS, along with other industry standards.
In All in all, the Meta Data Coalition played a critical role in advancing the field of data warehousing by developing common standards for managing meta-data. While the coalition is no longer active, its legacy lives on through the standards that it helped to create.
