“…An application implemented by using an object-oriented language with non-procedural statements embedded with a relational database as a data storage, consists of four main components. There is the application itself, the database schema, stored data and the object-relational mapping [11]. Refactoring the application can affects the database.…”

Object-relational database applications implemented in conventional procedural programming languages such as C, C++, and Java along with the embedded statements expressed in the non-procedural programming languages such as OQL, SQL and XQuery. Therefore, using transformation rules to optimise these applications by balancing the data processing load between the client and the server sides is required. Refactoring object-oriented applications, is one way to preserve output of the application but apply changes on design level. Implementation of object-relational applications with a large amount of procedural code, remains the majority of the dataprocessing to the client side. This often has catastrophic consequences for the performance of the application. Transformation rules need to be applied in an efficient way to come up with optimised applications.This research evaluates whether using transformation rules can be consider as a refactoring technology which can transfer the nonoptimise object-relational application to the optimise ones. A systematic experimental study was conducted by incorporating transformation rules to monitor the number of Blocks-Read operations before and after applying the rules. It was concluded that as rules applied in an efficient way, the performance of applications increased. Also the efficient way of applying the rules is proposed.

Model-driven software development is surrounded by numerous myths and misunderstandings that hamper its adoption. For long, our students were victims of these myths and considered MDSD impractical and only applied in academy. In this paper we discuss these myths and present our experience with devising an MDSD course that challenges them and motivates students to understand MDSD principles. The main contribution of this work is a set of MDSD teaching guidelines that can make the course pragmatic in the eyes of students - programmers. These guidelines introduce MDSD from the viewpoint of a programmer as a pragmatic tool for solving concrete problems in the development process. In our MDSD course we implemented the presented guidelines. The course shows several techniques and principles of model-driven development in multiple incremental iterations instead of concentrating on a single tool. At the same time we unite these techniques by using a dynamic visualisation tool that shows to the students the whole infrastructure in the big picture. The course is implemented as an iterative incremental MDSD case study. The paper concludes with a survey performed with our students that indicates positive results of the approach.
