We will first build the conceptual data model (CDM) to capture the scope of the application
through key concepts and relationships. Then, using the CDM as our starting point, we will
complete the logical data model (LDM) to capture the detailed business solution. Next, us-

capture the detailed technical solution, leveraging embedding, referencing, sharding, and
indexing. The PDM can then be implemented as collections in a MongoDB database.
