Abstract
This diploma thesis deals with the model driven development of a web-based
archaeological information system. The development is supported by the code
generator AndroMDA. The completed application has to administer locations
and findings, including their image-documents, of an archaeological project.
Following the trend for abstraction in the practical computer science, the
development and propagation of UML as well as UML based model driven
software development, the model focuses on the implementation of this application,
too. The model is not only in use during the analysis and design
of the application, but together with the code generator this leads to early
executable prototypes and milestones of the project and assist interaction
with the user.
The application is realized as a web-application to ensure multiple user access
to the same data. The access to the data is secured by an authentication.
Additionally, the users have roles to separate user groups with different
access-levels. There are three different roles: administrators of the application
(Administrator), normal users with read/write-access on the data
(StandardUser) and users with read-only-access (Reader).
In addition to data input and access, users can export the data in PDFand
Shapefile-format. With the PDF-format it’s possible to print and share
the data for viewing and archiving. As geographical information systems can
import the Shapefile-format, the application serves as an interface to GIS
applications.
It is possible to share data between two installations of the application.
