Entity tables and entity identifiers

An entity table is a table that contains data about a specific type of entity. An entity table represents the link between Siren Investigate and one or more Elasticsearch indices that you intend to explore.

For example, a Companies entity table, might contain hundreds of thousands of records about companies (the entity) and their attributes, such as their location, a description, the date they were founded, and so on.

Entity identifiers (EIDs) are typically derived from a value in one or more entity tables. They can be useful for finding connections between disparate data sets.

For example, a Companies entity table and an Investors entity table might both contain data about cities and people. By making these values entity identifiers, there are more opportunities to connect and find patterns in the data.

In this section, you will learn how to create and configure both entity tables and EIDs.
