Hello everyOne,

When designing and developing new large commercial business
applications, what is the preferred charting scheme as part of the
program and system documentation?. I know in the IT world its
always horses for courses and depending on where you are working,
however, maintenance, modification and enhancements are always
a major part of any large business application in the long run.

There are some methods that seem to be favored and work very well
for describing different sections of a program or a system, which
I can list three of them here -- perhaps there is a better
approach that you would like to pointOut, which makes
maintainability a much easier task:

1). Data Flow Diagram: to show the flow of data thru the complete
system and its subSystem modules.

2). Decision Table: to show listing of the actions required for
numerous if..else..and case evaluate conditions.

3). Data Structure Diagram: to show system data and relationship
between the data entities within the file system or dataBase.

Hi Kellie,

just as a note for next time, you will get a better response posting
such a general RDB (Relational Database) question to the COMP.DATABASES
newsgroup.

COMP.DATABASES.RDB is specific to the Oracle Rdb database (not the same
as the Oracle Classic Database).

There are many methods with associated diagram and modeling techniques.
The next link gives a taste of the various diagrams one may encounter in
any one specific software development shop.

Agile software development is a conceptual framework for undertaking
software engineering projects. There are a number of agile software
development methodologies, such as those espoused by the Agile Alliance,
a non-profit organization.

UML is increasingly being adopted, but is not specific to data modeling
for databases, and is intended as a modeling and specification technique
and not a method or life cycle Software Engineering tool.
