Use Connectors To extract Metadata
This section is intended for all the connectors that enable the extraction of Data Catalog metadata from target systems.
The Crawling feature allows you to populate the Data Catalog metadata starting from target systems, typically relational databases or with JDBC support. An appropriately configured Blindata Agent instance is required to set up the metadata crawling jobs.
Crawling works through two strategies:
-
SQL: through the extraction and analysis of the metadata present on the catalogs of the target systems
-
JDBC DRIVER: by reading and analyzing the metadata offered by the system’s JDBC driver
Depending on the needs and the type of system, one or the other strategy may be useful. Both are configurable in queries that extract data.
Blindata also allows enabling the extraction of Data Catalog metadata from target systems that are not relational databases or do not support JDBC.
