MetaData
Metadata—information that describes data—is the foundation of all information management initiatives aimed at increasing efficiency across an enterprise.
What Is Metadata?
Metadata is often generally described as “information about data.” More precisely, metadata is the description of the data itself, its purpose, how it is used, and the systems used to manage it. This usually includes
• Data model definitions
• Data transformation descriptions
• Process and flow information, such as schedules and logs
• Business intelligence systems description, such as cubes, dimensions, and metrics
• Any other type meaningful information, such as semantics.
Where Is metadata?
Metadata is scattered across the information system
• As data model descriptions in database dictionaries
• In Extensible Markup Language (XML), Document Type Definition (DTD), and XML Schema Definition (XSD) files
• In proprietary systems
• As pieces of code that perform data processing tasks
• In unstructured documents,such as Microsoft Word documents and spreadsheets
Metadata is also part of the knowledge held by a company’s staff

Why Is Metadata Critical?
You can think of metadata as the lines and points that draw the plan of the enterprise architecture. Accurate and comprehensive metadata enables organizations to evaluate their architecture’s efficiency and eases the process of changing this architecture.
Metadata is now critical to information management initiatives such as MDM (Master Data Management), customer data integration (CDI), product information management (PIM), and product data management (PDM). Such initiatives focus on creating and maintaining a clean, accurate view of corporate reference data that is shared across all operational and analytic systems.
MANAGING METADATA WITH ORACLE
Oracle Data Integrator provides all the features you need to retrieve, enrich, extend, and leverage existing metadata for agile corporate enterprise architecture.
Oracle Data Integrator is built around an open, comprehensive metadata repository, which can be installed on relational databases such as Oracle, Microsoft SQL Server, IBM DB2 UDB, IBM DB2/400, Informix, Sybase AS Anywhere, Sybase AS Enterprise, and Sybase ASIQ. Because metadata is stored in database tables, the repository is completely open and can be used as a source by any reporting system.
A metadata repository is a database of data about data (metadata). The purpose of the metadata repository is to provide a consistent and reliable means of access to data. The repository itself may be stored in a physical location or may be a virtual database, in which metadata is drawn from separate sources. Metadata may include information about how to access specific data, or more detail about it, among a myriad of possibilities.
CONCLUSION
Oracle Data Integrator places metadata at the center of its architecture. It provides features for retrieving, enriching, extending, managing, and leveraging this metadata as a foundation for meeting business needs
