US 8,150,882 B2 · Mapping from objects to data model

Abstract

Aspects of the subject matter described herein relate to mapping from application objects to an abstract data model. In aspects, a mapper receives registrations that indicate behavior (e.g., how objects are constructed, modified, or examined) of application objects. The behavior may be specified using user-supplied expressions. The mapper aggregates this data and uses it to map application requests for data access into one or more operations that operate on the abstract data model. A data access layer may then translate the operations into actions to access data corresponding to the requests from a store. If appropriate, data obtained from the store may then be inserted into application objects as indicated by the registrations.

Dependent claims

A method implemented at least in part by a computer, the method comprising:

receiving a data access request from an application that has objects that conform to an object model of the application, the object model comprising a collection of objects through which the application is able to examine and manipulate application data;
based at least in part on an expression that associates a behavior of an object that conforms to the object model to at least one operation associated with an abstract data model, mapping the data access request into a set of one or more operations that operate on the abstract data model, the abstract data model indicating how data is represented and accessed from a data store;
and
providing the one or more operations to a data access component to access data corresponding to the request from the data store.

An apparatus, comprising at least one processing unit and at least one computer-readable medium storing instructions executable by the at least one processing unit to facilitate implementation of:

an expression store operable to store and provide access to expressions that describe behaviors of objects that conform to an object model of an application, the object model comprising a collection of objects through which the application is able to examine and manipulate application data, the behaviors indicating actions to access data associated with the objects;
an abstract data model store operable to store and provide access to an abstract data model that indicates structure and relationships of data store data corresponding to the application data;
an expression aggregator operable to receive an expression that describes a behavior of an object that conforms to the object model and further operable to aggregate information about the behavior with other information about other behaviors, if any, of the object;
a mapping component operable to receive a request from the application to access data pertaining to the object and to map the request into one or more operations that operate on the abstract data model to obtain data from a data store based at least in part on aggregated information, if any, about behavior of the object.
