Mobile data and software update system and method

Data is shared between multiple enterprise data sources and mobile clients in a distributed system such that requests from a mobile client for enterprise data are received, the appropriate enterprise data sources that contain the requested data are determined, and the enterprise data is retrieved from the determined enterprise data sources. When the enterprise data is retrieved, it is converted into a relational format that can relate the retrieved data, even if the data comes from multiple enterprise data sources. The converted enterprise data is stored in a relational data store in the mobile client. In this way, mobile applications can be fully integrated with data from multiple enterprise data sources and data updates and configuration changes can be distributed to and from the mobile clients in real-time, without using interim data storage, and thereby avoiding complicated synchronization and data conflict issues between the enterprise data sources and the mobile clients.
