Abstract: Architecture that employs multi-row entities to store solution components using columns, properties and logic that track solution components by storing different versions (states) of the component into multiple rows. Component modification includes adding and/or modifying multiple rows, thereby facilitating support operations such as uninstall by retaining versions information of the same component. A master solution component table tracks all the root components of a solution, and logic implemented in code traverses the root nodes to discover all children nodes to efficiently track all components of a solution. The logical states of protected and unprotected for solution allow customers to develop multiple solutions on the same system (organization), protect a solution, and build composite applications with multiple solutions involved (layering of solutions). Multi-row storage facilitates the storage of the component definition and associated solution.
