Virtual backward associations for generic request handling based on models

A non-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for accessing a database layer through one or more data models, the operations comprising:

• receiving, in response to instantiation of an application that enables access to data within the database layer, a data model provided as a computer-readable file, the data model defining a set of associations between two or more tables stored in the database layer, each association comprising a foreign key that defines a first uni-directional association between two tables;
• processing the data model to provide a set of inverted associations, each inverted association being specific to a respective association in the set of associations and defining a second uni-directional association between two tables;
• generating an enriched data model comprising the set of associations of the data model and the set of inverted associations;
• and
• hosting a service that stores the enriched data model as an in-memory data object and uses the enriched data model to enable access to the data within the database layer based on one or more queries submitted from a web client during a runtime and that deletes the enriched data model after the runtime.

A system, comprising:

• a computing device;
• and
