Automatically Detecting ORM Performance Anti-Patterns on C# Applications Tuba Kaya Master's Thesis 23–09-2015
Automatically Detecting ORM Performance Anti-Patterns on C# Applications Tuba Kaya Master's Thesis 23–09-2015 Master Software Engineering University of Amsterdam Supervisors: Dr. Raphael Poss (UvA), Dr. Giuseppe Procaccianti (VU), Prof. Dr. Patricia Lago (VU), Dr. Vadim Zaytsev (UvA) i Abstract In today’s world, Object Orientation is adopted for application development, while Relational Database Management Systems (RDBMS) are used as default on the database layer. Unlike the applications, RDBMSs are not object oriented. Object Relational Mapping (ORM) tools have been used extensively in the field to address object-relational impedance mismatch problem between these object oriented applications and relational databases. There is a strong belief in the industry and a few empirical studies which suggest that ORM tools can cause decreases in application performance. In this thesis project ORM performance anti-patterns for C# applications are listed. This list has not been provided by any other study before. Next to that, a design for an ORM tool agnostic framework to automatically detect these anti-patterns on C# applications is presented. An application is developed according to the designed framework. With its implementation of analysis on syntactic and semantic information of C# applications, this application provides a foundation for researchers wishing to work further in this area. ii Acknowledgement I would like to express my gratitude to my supervisor Dr. Raphael Poss for his excellent support through the learning process of this master thesis. Also, I like to thank Dr. Giuseppe Procaccianti and Prof. Patricia Lago for their excellent supervision and for providing me access to the Green Lab at Vrije Universiteit Amsterdam. -

An Approach to Maintainable Model Transformations with an Internal DSL
An approach to maintainable model transformations with an internal DSL Master thesis of Georg Hinkel At the Department of Informatics Institute for Program Structures and Data Organization (IPD) Reviewer: Prof. Dr. Ralf Reussner Second reviewer: Prof. Dr. Walther Tichy Advisor: Dr. Lucia Happe Second advisor: Dr. Thomas Goldschmidt Duration:: 1st May 2013 – 31th October 2013 KIT – University of the State of Baden-Wuerttemberg and National Research Center of the Helmholtz Association www.kit.edu I declare that I have developed and written the enclosed thesis completely by myself, and have not used sources or means without declaration in the text. PLACE, DATE ......................................... (Georg Hinkel) iii Abstract In recent years, model-driven software development (MDSD) has gained popularity among both industry and academia. MDSD aims to generate traditional software artifacts from models. This generation process is realized in multiple steps. Thus, before being transformed to software artifacts, models are transformed into models of other metamodels. Such model transformation is supported by dedicated model transformation languages. In many cases, these are entirely new languages (external domain-specific languages, DSLs) for a more clear and concise represen- tation of abstractions. On the other hand, the tool support is rather poor and the transformation developers hardly know the transformation language. A possible solution for this problem is to extend the programming lan- guage typically used by developers (mostly Java or C#) with the re- quired abstractions. This can be achieved with an internal DSL. Thus, concepts of the host language can easily be reused while still creating the necessary abstractions to ease development of model transformations. -

However, this can take a long time and more Abstract — It is very important to test and monitor the costs depending on the complexity of the system. Also, operation of Programmable Logic Controller (PLC) in real this solution isn’t modular because it is difficult and time time (online). Nowadays, conventional, but expensive consuming to rebuild the model if some changes are monitoring systems for PLCs, such as Supervisory Control necessary. and Data Acquisition (SCADA) systems, software and hardware simulators (or debuggers), are widely used.
