Example text
When a client wants to use an object, it accesses the database, retrieves the object from it and uses it. This seems like a quick and simple solution, but it has negative impacts on the design. Databases are part of the infrastructure. A poor solution is for the client to be aware of the details needed to access a database. For example, the client has to create SQL queries to retrieve the desired data. The database query may return a set of records, exposing even more of its internal details. When many clients have to create objects directly from the database, it turns out that 52│DOMAIN DRIVEN DESIGN QUICKLY such code is scattered throughout the entire domain.
The creation of an object does not involve the creation of others, and all the attributes needed are passed via the constructor. • The client is interested in the implementation, perhaps wants to choose the Strategy used. • The class is the type. There is no hierarchy involved, so no need to choose between a list of concrete implementations. Another observation is that Factories need to create new objects from scratch, or they are required to reconstitute objects which previously existed, but have been probably persisted to a database.
Should we make all objects entities? Should every object have an identity? We may be tempted to make all objects entities. Entities can be tracked. But tracking and creating identity comes with a cost. We need to make sure that each instance has its unique identity, and tracking identity is not very simple. It takes a lot of careful thinking to decide what makes an identity, because a wrong decision would lead to objects with the same identity, something that is not desired. There are also performance implications in making all objects entities.
