The Data Warehouse system plays a major role in guiding decision-making within an organization by providing crucial information for decision support systems. These are systems that streamline the integration of information from heterogeneous sources. They integrate data from both internal and external sources. In recent years, they have played an important role in the decision-making process. In the last few decades, the amount of information available on the web that can be used for decision support systems has increased significantly. As a result of this rapid growth, a common format, such...

Correcting design decay in source code is not a trivial task. Diagnosing and subsequently correcting inconsistencies between a software system's code and its design rules (e.g., database queries are only allowed in the persistence layer) and coding conventions can be complex, time-consuming and error-prone. Providing support for this process is therefore highly desirable, but of a far greater complexity than suggesting basic corrective actions for simplistic implementation problems (like the ''declare a local variable for non declared variable'' suggested by Eclipse). This focuses on...
