Data store interface that facilitates distribution of application functionality across a multi-tier client-server architecture

A server computer system comprising:

• a non-transitory storage device having embodied therein instructions operable to process requests from a client computer system;
• and
• one or more processors coupled to the non-transitory storage device and operable to execute the instructions to perform a method comprising:
• caching into a hierarchical data map comprising a random access memory-resident data structure a plurality of data points from a database associated with the server computer system, wherein each of the plurality of data points includes a field name and a calculated value;
• receiving a request from the client computer system, wherein the request contains one or more input values that are to be stored within the hierarchical data map;
• and
• responsive to the request:
• transferring the one or more input values to one or more target data points of the plurality of data points;
• updating the calculated value of at least one of the plurality of data points based on the one or more target data points and a formula corresponding to the calculated value;
• and
• persisting changed contents within the hierarchical data map to the database.

A non-transitory computer-readable storage medium tangibly embodying a set of instructions, which when executed by one or more processors of a server computer system, cause the one or more processors to perform a method comprising:

• caching into a hierarchical data map comprising a random access memory-resident data structure a plurality of data points from a database associated with the server computer system, wherein each of the plurality of data points includes a field name and a calculated value;
• receiving a request from a client computer system, wherein the request contains one or more input values that are to be stored within the hierarchical data map;
• and
• responsive to the request:
• transferring the one or more input values to one or more target data points of the plurality of data points;
• updating the calculated value of at least one of the plurality of data points based on the one or more target data points and a formula corresponding to the calculated value;
• and
• persisting changed contents within the hierarchical data map to the database.
