Projects often involve multiple teams of developers in different locations. The different teams make updates to a central or shared database(s) that can store information about the project, such as progress. Each team or even different members of the different teams can check out instances of a representation of a model for the project. The different teams/members can independently modify their instance with data specific to that member and/or team. Database operations embedded in the individual instances are then executed on the database(s) to persist the data from their individual instances to the database(s). Database mechanisms can handle locking and/or conflicts that may arise from performance of the database operations. A manager can then request a report from the database(s), and the report with data from the different members and/or teams can be generated from the database(s).
