Low-Latency Database Analysis Using External Data Sources

A database analysis system comprising:

• an in-memory database;
• a memory storing instructions for low-latency database analysis using an external data source;
• and
• a processor that executes the instructions to:
• generate, in the in-memory database, an unpopulated database schema corresponding to a populated database schema stored in an external database;
• send, to the external database, a data query generated by the database analysis system in accordance with the unpopulated database schema;
• obtain results data output by the external database in response to execution of the data query;
• and
• output the results data.

A non-transitory computer-readable storage medium including executable instructions which when executed by one or more processors cause the one or more processors to perform operations comprising:

• generating, in an in-memory database of a database analysis system, an unpopulated database schema corresponding to a populated database schema stored in an external database;
• sending, by the database analysis system, to the external database, a data query generated by the database analysis system in accordance with the unpopulated database schema;
• obtaining, by the database analysis system, results data output by the external database in response to executing the data query;
• and
• outputting the results data.
