Marine observatories based on sensor networks provide continuous ocean monitoring. The design phase of such systems, which is part of the complete development life cycle, is a complex and challenging task. The design difficulties may induce the designers to make architectural design errors during the design phase. This study aims to identify the best design approach that helps sensor networks designers in preventing errors and validating models at an early phase. In addition, it introduces a new environmental constraint that should be taken into consideration when building design models. To ...

In this thesis, we demonstrate how developers can make use of the model driven architecture (MDA) techniques to make the software development process more reliable, robust and less costly. We will focus on discussing a set of transformation techniques that together, transform a PSM (Platform Specific Model) into a code model written in Visual Basic.NET and an ER (Entity Relationship) model developed using SQL (Structured query Language) and targeting the Microsoft SQL Server relational database management system. The source model is assumed to be represented using UML (Unified Modeling Language). ...
