Database management system (DBMS) employing a relational datastore and a multi-dimensional database (MDDB) for servicing query statements in a manner transparent to client machine
First Claim
1. A database management system comprising:
- a relational data store configured to store fact data;
a non-relational data store configured to store aggregated fact data;
a communication interface operably connected between the relational data store and the non-relational data store for the communication of fact data from the relational data store to the non-relational data store and for the communication of aggregated fact data from the non-relational data store to the relational data store; and
a computer system comprising computer hardware, the computer system programmed to implement;
a query servicing mechanism configured to service one or more natural language queries from a user, the query servicing mechanism comprising;
a query processing mechanism configured to process a given natural language query using operations to;
determine whether servicing the given natural language query needs data stored in the relational data store or in the non-relational data store;
upon determining that servicing the given natural language query needs data stored in the relational data store,
automatically route the given natural language query to the relational data store, so that data is accessed from the relational data store and forwarded to the query processing mechanism for use in servicing the given natural language query, in a manner transparent to the user; and
wherein upon determining that servicing the given natural language query needs data stored in the non-relational data store,
automatically route the given natural language query to the non-relational data store, so that data can be accessed and forwarded to the query processing mechanism for use in servicing the given natural language query, in a manner transparent to the user.

Abstract
A database management system (DBMS) for servicing query statements through one or more client machines. The DBMS comprises a query interface adapted to receive query statements from the client machines. The query handling mechanism (i) receives each request from the query interface, (ii) extracts a set of dimensions associated with the request, (iii) uses the dimensions to retrieve aggregated fact data from a multi-dimensional database (MDDB), and (iv) forwards retrieved aggregated fact data to the query processing mechanism for subsequent processing. When the query processing mechanism determines that servicing of one or more query requests require data stored in the relational tables, then the query processing mechanism automatically routes the requests to the relational data tables, so that data can be accessed from the relational tables and forwarded to the query processing mechanism for use in servicing the requests, in a manner transparent to the client machine.

7. A method comprising:
by a computer system comprising computer hardware; receiving one or more natural language queries from a user; determining whether servicing a given natural language query of the one or more natural language queries needs data stored in a relational data store or in a non-relational data store, wherein the relational data store is configured to communicate fact data to the non-relational data store and the non-relational data store is configured to communicate aggregated fact data to the relational data store; in response to determining that servicing the given natural language query needs data stored in the relational data store, automatically routing the given natural language query to the relational data store, so that data is accessed from the relational data store and forwarded to the user; and in response to determining that servicing the given one or more natural language queries needs data stored in the non-relational data store, automatically routing the given natural language query to the non-relational data store, so that data can be accessed and forwarded to the user. - View Dependent Claims (8, 9, 10, 11)

12. A non-transitory computer-readable medium having instructions stored thereon that, if executed by a computing device, cause the computing device to perform operations comprising:
-
receiving one or more natural language queries from a user; determining whether servicing a given natural language query needs data stored in a relational data store or in a non-relational data store, wherein the non-relational data store is generated via a segmented aggregation process involving aggregation along multiple dimensions in a determined sequence; in response to determining that servicing the given natural language query needs data stored in the relational data store, automatically routing the given natural language query to the relational data store, so that data is accessed from the relational data store and forwarded to the user; and in response to determining that servicing the given natural language query needs data stored in the non-relational data store generated via the segmented aggregation process, automatically routing the given natural language query to the non-relational data store, so that data can be accessed and forwarded to the user. - View Dependent Claims (13, 14, 15, 16)
