This is made possible by bridging functional and technical terms through the lineage. In addition, in order to standardize its content, taxonomies and controlled vocabularies are often used to encode values according to code lists.įinally, a data catalog acts as a directory to locate information and make it available to users, providing all users with a single point of reference for accessing it. For this reason, each database should have its associated data dictionary.įor the completion of the metadata requested in a data dictionary, there are pre-designed guides and templates such as the following example provided by the U.S. This metadata helps users to understand the data from a technical point of view in order to be able to use it properly. The documentation of these transformations will automatically provide us with the lineage of the data, understood as the traceability throughout its life cycle. In other words, it includes technical aspects such as the type of data, format, length, possible values it can take and even the transformations it has undergone, without forgetting the definition of each field. While a business glossary, or data vocabulary, tries to give functional meaning to the indicators or concepts that are handled in a way that ensures that the same language is spoken, abstracting from the technical world, as explained in this article, a data dictionary tries to document the metadata most closely linked to its storage in the database. It is common that when we talk about data dictionary, it is confused with business glossary or data vocabulary, however, they are different concepts. However, in order to make proper use of data, it is necessary to have good documentation, through a data dictionary. Using simple techniques, it is possible to extract value from them that was unimaginable just a few years ago. New technologies have enabled a data-driven globalization in which everything that happens in the world is interconnected. Data has occupied a fundamental place in our society in recent years.
