The predefined models can also be reused to define new model by extension or derivation (an object class can have a superclass), or to simply define new resource types to allow bringing the metadata via CSV files for unsupported metadata sources. 2021-03-23 BI report and model metadata that is imported by MetaBrokers and bridges from BI tools such as IBM Cognos® and BusinessObjects.

The Phalcon\Mvc\Model\MetaData object is offering this functionality, transparently querying the database and generating the necessary data from the database schema. The data can then be stored in a data store (such as Redis, APCu etc.) to ensure that the database is not queried for the schema every time a query is executed.
Relational databases (most common type of database) store and provide access not only data but also metadata in a structure called data dictionary or system catalog. It holds information about: tables, columns, data types The metadata model is a snapshot (or in GraphQL terms, a graph) of how Tableau interprets and relates a set of objects on your Tableau Online site or Tableau Server. From the metadata model, you can understand the dependencies and relationships in your data.
