Object Relational Mapping for Enterprise Application Architecture A thesis submitted by Musafare Machisa to Regis University In partial fulfillment of the requirement for the degree of Master of Science In Computer Information Technology Acknowledgements I would like to thank my advisor, Rob Sjodin for devoting his time answering questions, meeting with me and offering guidance on the project. I would also like to thank my wife and kids for their understanding and patience during the time that I worked day, night and weekends to complete this project. MSC696B 4 Abstract This project investigates the patterns/techniques used and issues that are encountered in developing object-oriented (OO) to relational data mappings for enterprise application architectures. The research will identify the different techniques of object relational data mapping as documented by Martin Fowler in "Patterns of Enterprise Application Architecture" (text for MSCS 630). A prototype implementation will be developed using the techniques found in this research. The goal of the project is to analyze and understand Martin Fowler's patterns and other object relational mapping patterns used in industry and to recommend a set of "best practices".

  • An Experimental Study of the Performance, Energy, and Programming Effort Trade-Offs of Android Persistence Frameworks
    An Experimental Study of the Performance, Energy, and Programming Effort Trade-offs of Android Persistence Frameworks Jing Pu Thesis submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science in Computer Science and Applications Eli Tilevich, Chair Barbara G. Ryder Francisco Servant July 1, 2016 Blacksburg, Virginia Keywords: Energy Efficiency; Performance; Programming Effort; Orthogonal Persistence; Android; Copyright 2016, Jing Pu An Experimental Study of the Performance, Energy, and Programming Effort Trade-offs of Android Persistence Frameworks Jing Pu (ABSTRACT) One of the fundamental building blocks of a mobile application is the ability to persist program data between different invocations. Referred to as persistence, this functionality is commonly implemented by means of persistence frameworks. When choosing a particular framework, Android|the most popular mobile platform—offers a wide variety of options to developers. Unfortunately, the energy, performance, and programming effort trade-offs of these frameworks are poorly understood, leaving the Android developer in the dark trying to select the most appropriate option for their applications. To address this problem, this thesis reports on the results of the first systematic study of six Android persistence frameworks (i.e., ActiveAndroid, greenDAO, Orm- Lite, Sugar ORM, Android SQLite, and Realm Java) in their application to and performance with popular benchmarks, such as DaCapo. Having measured and ana- lyzed the energy, performance, and programming effort trade-offs for each framework, we present a set of practical guidelines for the developer to choose between Android persistence frameworks. Our findings can also help the framework developers to optimize their products to meet the desired design objectives.

  • Security in Domain-Driven Design Author: Michiel Uithol
    Security in Domain-Driven Design Author: Michiel Uithol Supervisors: dr.ir. M.J. van Sinderen dr.ir. L. Ferreira Pires T. Zeeman (Sogyo) E. Mulder (Sogyo) Security in Domain Driven Design By Michiel Uithol ii Security in Domain Driven Design By Michiel Uithol Abstract Application development is a process that becomes increasingly complex depending on the intricacy of the application being developed. Development techniques and methodologies exist to manage and control the complexity of this development process. Amongst the techniques introduced to manage the complexity of the application development process is Domain-driven design (DDD). DDD prescribes a specific application of separation of concerns to the application model into a domain model and DDD-services. This Masters assignment investigates how to handle issues concerning the modelling and implementation of authorization and authentication functionality in an application developed according to the DDD principle of separating domain-related functionality from domain-independent functionality. This means an application where security functionality is located in a DDD-service. The goal of this Masters assignment is to find design options to separate security from domain-related functionality and provide guidelines for usage of these design options. To find the best design options, the problem is explored and the levels of coupling between DDD-services and the domain implementation are clarified. Criteria for the application design phase are that the design should comply with the DDD principle of separating domain-related functionality from domain-independent functionality, and that the design should provide usability and efficiency when implemented. Two prototypes use Aspect-Oriented Programming (AOP) to separate security logic into a DDD-service.

  • Comparison of Performance Between Raw SQL and Eloquent ORM in Laravel
    Comparison of performance between Raw SQL and Eloquent ORM in Laravel Faculty of Computing i Blekinge Institute of Technology SE-371 79 Karlskrona Sweden Contact Information: Author(s): Ishaq Jound E-mail: [email protected] Hamed Halimi E-mail: [email protected] University advisor: Mikael Svahnberg Faculty of Computing Faculty of Computing Internet : www.bth.se Blekinge Institute of Technology Phone : +46 455 38 50 00 SE-371 79 Karlskrona, Sweden Fax : +46 455 38 50 57 i ABSTRACT Context. PHP framework Laravel offers three techniques to interact with databases, Eloquent ORM, Query builder and Raw SQL. It is important to select the right database technique when developing a web application because there are pros and cons with each approach. Objectives. In this thesis we will measure the performance of Raw SQL and Eloquent ORM, there is little research on which technique is faster. Intuitively, Raw SQL should be faster than Eloquent ORM, but exactly how much faster needs to be researched. Methods. To measure the performance of both techniques, we developed a blog application and we ran database operations select, insert and update in both techniques. Conclusions. Results indicated that overall Raw SQL performed better than Eloquent ORM in our database operations. There was a noticeable difference of average response time between Raw SQL and Eloquent ORM in all database operations. We can conclude that Eloquent ORM is good for building small to medium sized applications, where simple CRUD operations are used for the small amount of data. Typically for tasks like inserting a single row into a database or retrieving few rows from the database.

[email protected] Abstract. An Adaptive Object-Model (AOM) is a dynamic meta-modeling technique where the object model of the system is explicitly defined as data to be interpreted at run-time. It fits the model-driven approach to software engineering. The object model comprehends the specification of domain objects, states, events, conditions, constraints and business rules. Several design patterns, that have before been documented, describe a set of good-practices for this architectural style. This paper approaches data and metadata evolution issues in the context of AOMs, by describing three additional patterns | History, Versioning and Migration. They establish ways to track, version, and evolve information, at the several abstraction levels that information may exist in an AOM. Key words: Adaptive object models, AOM, Model driven engineering, MDE, Design patterns, Meta-modeling, Versioning, History, Migration. 1 Introduction Developers who are faced with the system requirement of a highly-variable domain model, by systemati- cally searching for higher flexibility of object-oriented models, usually converge into a common architec- ture style typically known as Adaptive Object-Model (AOM) [1].
