Enterprise Data Catalog Overview
Enterprise Data Catalog brings together all data assets in an enterprise and presents a comprehensive view of the data assets and data asset relationships. A data asset is a type of data object, such as a physical data source, HDFS, or big-data repository. The data assets in the enterprise might exist in relational databases, purpose-built applications, reporting tools, HDFS, and other big-data repositories.
Enterprise Data Catalog captures the physical and operational metadata for a large number of data assets that you use to determine the effectiveness of enterprise data. Metadata is data about data. Metadata contains details about the structure of data sources. Metadata also includes information, such as data patterns, data types, relationships between columns, and relationships between multiple data sources.
Enterprise Data Catalog gathers information related to metadata across the enterprise. The metadata includes column data statistics, data domains, data object relationships, and data lineage information. A comprehensive view of enterprise metadata can help you make critical decisions on data integration, data quality, and data governance in the enterprise.
Enterprise Data Catalog addresses the following key questions related to metadata in the enterprise:
- •What content does a data asset contain?
- •What does the content in a data asset mean?
- •Who is responsible for a specific data asset in the enterprise?
- •Which is the source for data in a data asset?
- •What sensitive data does the enterprise have?
- •Where is the sensitive data located?
