Using Layers in Software Architecture

Layers are useful in adding system environment information to evolve the analysis model into a design model of the software system.
Each layer represents an element of the software architecture such as the problem domain, data management, user interface, and physical architecture.
Layers can be portrayed using packages and package diagrams.
The idea of separating the different elements of the architecture into separate layers can be traced back to the MVC architecture of Smalltalk.
Smalltalk created the Model-View-Controller (MVC) architecture where Models implemented the application logic (problem domain) and Views and Controllers implemented the logic for the user interface.
The foundation layer contains classes that are necessary for any object-oriented application to exist such as fundamental data types, fundamental data structures, and utility classes.
The problem-domain layer requires further detailing of the classes to implement them effectively and efficiently.
The data management layer addresses issues involving the persistence of objects contained in the system and contains Data Access and Manipulation (DAM) classes.
DAM classes allow problem domain classes to be independent of the storage used, increasing the portability of the evolving system.
The types of classes that appear in the data management layer deal with how objects can be stored and retrieved.
There are different storage options such as sequential files, random access files, relational databases, object/relational databases, object-oriented databases, and NoSQL data stores, each optimized to provide solutions for different access and storage problems.
A complete description of all the issues related to the data management layer is presented in Chapter 9 of the book.
