Kinds of Implementation Elements
Implementation Elements can generally be categorized as files and directories. Files can be further categorized as
Source code files
These are files that may be directly modified by a developer. This includes:
compilable source code (such as : .h, .cpp and .hpp files for C++, CORBA IDL, or .java for
interpreted source (HTML, various scripting languages), and user-modifiable data files (such as
database tables, configuration files, graphics files, and so on).
These are files that are not intended to be directly modified by a developer. They are
derived from source files.
Some derived files are intended to be used in the operational system (such as DLLs, JARs, and
EXEs). Others are the intermediate results of compilation (for example, .o files from compiling C++
and .class files from compiling java code).
In version 1.3 of the Unified Modeling Language (UML) specification, files are modeled as UML components. In UML 1.4,
the representation changed to be UML artifact. Many tools and UML profiles continue to use components for modeling
In any case, modeling of files and directories should be be done sparingly, unless there is some automated support.
Files can be viewed in the project directory structure, and the relationship between files and design elements is often
sufficiently clear from the directory structure and naming conventions.
