Developing Database Mobile Business Objects

Develop two samples of mobile business objects to see how they form the business logic for mobile applications. Create two mobile business objects, each using a database as its datasource, create a relationship between the two MBOs, and deploy them to SAP Mobile Server. Use the deployed project in the Object API application development tutorials.
