Course Overview
This course is intended to help those who are
planning to document existing legacy systems in order to properly
maintain, transform or migrate the legacy environment using visual
modelling techniques. The course is a hands-on experience with a
case study that provides the course participants practical
experience in the concepts taught.
Although the standard course is based on the use
of the Enterprise Architect modelling tool and a prescribed case-
study, it may be adapted to include other modelling tools and
client specific case studies.
The course provides a comprehensive outline to how
a legacy system documentation project should be approached and
executed. The following topics are covered:
A project approach
An overview to the project approach of how a
documentation project should be planned for and executed in a
legacy environment. It includes the introduction of a project
process, the use of the templates that are provided as part of the
course materials and the major deliverables of such a project. The
importance of modelling standards and how to develop these
standards are also discussed.
-
-
Understanding the legacy system - Understanding
the legacy system, its components, its language grammar and
environment. The aim is to understand the possibilities of how the
system can be broken up in components that may be mapped to the
UML. The re- usability of code and the identification of reusable
code are also discussed.
-
Mapping
the legacy system to the UML - The course participants are
introduced to the UML diagram framework, and how the different
component parts of the legacy system can be mapped to
it.
-
Documenting the model - Using the templates
provided as part of the course materials, the course participants
are taught how to model the legacy system in the Enterprise
Architect modelling tool. They are also taught how to generate
documentation and HTML reports.
-
Validating the model - Using the UML model as a
basis the course participants are taught how to validate the models
against the real life business processes. This serves to bring the
models to completion and a valid representation of the legacy
system it represents.
As part of the conclusion of the course some
possible scenarios are discussed on how these legacy system models
may be used to maintain the system, integrate it with other
systems, or to use it as a basis for a new system
development.
