12. An apparatus comprising: a processor; and a machine-readable medium having program code executable by the processor to cause the apparatus to, parse a set of records retrieved from a first database to identify a set of one or more data fields in each of the set of records, wherein the first database does not have a defined schema; determine statistically significant data fields of the set of data fields across the set of records, wherein statistically significant data fields are determined relative to a number of records in the set of records or determined relative to a number of indications for each of the set of data fields; identify a first plurality of database entities from the statistically significant data fields; determine, from a defined schema of a second database, a second plurality of database entities; and generate a unified data model for the first database and the second database based, at least in part, on the first and the second plurality of database entities.

The apparatus of claim 12 , wherein the program code executable by the processor to cause the apparatus to generate the unified data model further comprises program code executable by the processor to cause the apparatus to: determine a set of database entities based, at least in part, on merging and deduplicating the first plurality of database entities and the second plurality of database entities; indicate relationships among the set of database entities in the unified data model based, at least in part, on identification of associated database entities in at least one of the first and the second databases; and indicate properties of the set of database entities in the unified data model.
