The present invention extends to methods, systems, and computer program products for processing data-centric business models. An execution engine accesses a commingled data-centric application model that includes a data model for a data store and a business logic model for interacting with data entities contained in the data store. The execution engine receives an event related to the data store and identifies an involved data entity corresponding to the received event. The execution engine identifies a business logic rule indicated as affecting the involved data entity. The execution engine establishes a context for evaluating the identified business logic rule. The execution engine evaluates the conditions of the business logic rule in accordance with the established context. The execution engine executes any appropriate actions indicated in the business logic rule as a result of the conditions of the business logic rule being satisfied.
