A dynamic data service accepts requests for database operations from a client application, where the requests can be associated with a property, including a particular data member, of a data model template. The property has at least one attribute that can be instantiated in a plurality of configuration values. The property is instantiated with the at least one attribute having a configuration value that is appropriate for fulfilling a client request, including being instantiated a plurality of times with a plurality of configuration values. The dynamic data service can send the request to a database for execution and return execution results to the client application. The dynamic data service can allow for the more flexible design of client applications, as the client applications can use different configuration values, or can use combinations of configuration values. The dynamic data service can provide improved performance, as multiple configuration values can be use with a single data service and a single data model template.
