Heterogeneous database processing archetypes for hybrid system

A system comprising:

• one or more computer-readable media comprising a client-executable shell supporting heterogeneous archetypes of client application programs comprising a transactional application archetype and an analytical application archetype;
• wherein the client-executable shell is configured to direct requests for online transaction processing to a server-side transactional engine supporting online transaction processing on a database;
• and
• wherein the client-executable shell is configured to direct requests for online analytical processing to a server-side analytical engine supporting online analytical processing on the same database.

One or more computer-readable media comprising computer-executable instructions causing a computing system to perform a method comprising:

• receiving a first request, the first request being for performance of one or more analytical operations;
• fulfilling the first request by using an analytical engine, the analytical engine performing the one or more analytical operations via a single persistence in a database;
• sending a first response, the first response comprising one or more results of the one or more analytical operations;
• receiving a second request, the second request being for performance of a transactional operation, wherein the transactional operation is performed on at least one of the one or more results of the one or more analytical operations;
• fulfilling the second request by using a transactional engine, the transactional engine performing the transactional operation via a same single persistence in the database;
• and
• sending a second response, the second response comprising at least one result of the transactional operation;
• whereby a single system supports a plurality of different database processing archetypes.
