Almost every software developer has sometime in his life been confronted with |
| |
the problem of documenting his project. This, one would say banal matter, |
| |
consists of more problems than one would think. Software that does not include |
| |
quality detailed documentation is heading for downfall. In our document we will |
| |
try to illustrate some of the possibilities for quick and effective |
| |
documentation of software product. |

| |
The basic factor to think about is the target group. Common software user is |
| |
interested in different type of information than <!-- potencial --> application |
| |
developer. This needs to be taken into consideration. One needs to adapt the |
| |
form and content of documentation. That is why distinguish two different types |
| |
of documentation: |

| |
|
| |
Common user is usually not interested in software architecture nor it.s inner |
| |
implementation. He or she does not care how things are done, what means and |
| |
programming languages were used in the process of development. What interests |
| |
him/her the most is how the program runs, how is it used and also in what |
| |
environment and under which operation system it can be started. That is why the |
| |
emphasis should be put on detailed, but mainly understandable explanation of all |
| |
functions and possibilities of the program. |

|
| |
It is better if someone else than the author of the program writes the |
| |
user-oriented documentation. He may consider many things to be absolutely clear |
| |
while they may not be clear at all to the common user. It is appropriate if the |
| |
user-oriented documentation includes many examples and is written in awareness |
| |
that it will be read by person who doesn.t understand programming at all. |

| |
|
| |
A developer working on a project needs to have documented all the inner |
| |
technical matters of the software, such as class inheritance hierarchy, data |
| |
structure description as well as it.s attributes, list of source files, global |
| |
identifiers etc. The description of the correct use of corresponding |
| |
development tools used for the program creation should also be included. |
| |
|
| |
</para> |
| |
<para> |
| |
|
| |
The basic purpose of existence of developer-oriented documentation is the |
| |
maintenance and extensibility of the software product. It is an absolute must |
| |
to document all the nonstandard program constructions as well as a detailed |
| |
description of the process of synchronizing the program. |
| |

|
| |
It is now clear that these two types of documentation are absolutely different. |
| |
It is not possible that the documentation of the first type replaces the second |
| |
or the other way around. The developer-oriented documentation should be written |
| |
along with the program creation. If the inner implementation of structure |
| |
changes, the corresponding part of documentation is changed as well. It is |
| |
reasonable to start writing the user-oriented documentation as soon as possible, |
| |
but this should not be before the program reaches it.s basic functionality. |
| |
|
| |
</para> |
| |
<para> |
| |
|
| |
Both types of documentation are written by different people and the tools for |
| |
its creation and maintenance are adapted correspondingly. Their use is |
| |
illustrated in the following chapters of this document. |
