Code first is a better approach, if only because it is simpler. If the system is maintaining an XML model, the database itself, and also a bunch of classes, there is more to go wrong. Plain text code is also easier to work with, for example in source code tools, diff tools (comparing two versions) and the like.
During the implementation phase, the physical realization of the database and application designs are to be done. This is the programming phase of the systems development. This phase is needed when a new database is replacing an old system. logical database design. - physical database design. In the conceptual database design phase, the model of the data to be used independent of all physical considerations is to be constructed. The model is based on the requirements specification of the system.
