OpenMetadata enables you to discover your data using a variety of strategies, including: keyword search, data associations (e.g., frequently joined tables, lineage), and complex queries. Using OpenMetadata you can search across tables, topics, dashboards, pipelines, and services. The OpenMetadata standard and discovery UI provides for fine-grained and detailed metadata for assets and a their components (e.g., columns, charts), including support for complex data types such as arrays and structs.
Discover assets through frequently joined tables and columns as measured by the data profiler. You can also discover assets through relationships based on data lineage.
Tier tags enable you to annotate assets with their importance relative to other assets. The Explore UI enables you to filter assets based on importance. 
Use ownership metadata to determine the primary points of contact for any assets of interest in order to get help with any questions you might have.
Enable the data profiler to capture table usage statistics over a period of time. This happens as part of metadata ingestion. Data profiles enable you to check for null values in non-null columns, for duplicates in a unique column, etc. You can gain a better understanding of column data distributions through descriptive statistics provided.
See the [Connectors](../install/metadata-ingestion/connectors/) documentation for information on available connectors and how to integrate your services with OpenMetadata.
