<p>Arbetet handlar om utveckling av ett e-learningsystem och hur man kan säkra koden förframtiden. Dessutom handlar det om att undersöka en möjlig implementation av standardenSCORM samt att ta fram en ny databasmodell.Efter förundersökning togs beslutet att genomföra projektet som ett API i grunden medtestdriven utveckling och tillhörande dokumentation. De tekniker som användes var; HTML,CSS, XML, PHP, MySQL, Javascript, och Codeigniter.Resultatet blev som förväntat förutom att det inte gick att återanvända koden i den utsträckningsom först uppskattades utan istället återanvändes idéer och problemlösning.</p> / <p>This thesis is about an e-learning system and how to secure the code for future development. Inaddition, it is about a conceivable implemention of the SCORM standard and to develop a newdatabase model.After preliminary investigation it was decided to proceed with the project as an API and to usetest-driven development and also to write documentation. The techniques used were: HTML,CSS, XML, PHP, MySQL, Javascript, Codeigniter.The result was as expected except that it was not possible to reuse the code in the extent whichwas first estimated, but instead re-use ideas and how to solve problems.</p>

<p>This exam paper has been a collaboration between the writers and System Anderson AB. The assignment was about completing a client application, running on a PDA, and a server application, running as a web service. The web service handles the communication with System Anderssons existing database. The main goal for the application is that it will be used to increase efficiency in storage management. The client application will hold functions for withdrawal, purchase, delivering and inventory. This project brings up the implementation of the functions for withdrawal and purchasing.</p><p>A part of this exam paper contains the basic theory that underlies the project. It also contains a summary of the different choices that has been made.</p><p>The result of this exam paper is a well-functioning version of our application. The application contains functions for withdrawal and purchasing.</p>

<p>This paper discusses the process of software evolution and especially software migration in the context of .NET Technologies. Actually most of the companies that uses legacy systems implemented with procedural languages as C, Visual Basic and so on, meet some problems when new requirement specifications have to be integrated.</p><p>One possibility to deal with this situation is to choose a good migration strategy from these legacy systems towards new Object Oriented design.</p><p>There are some migration processes that enable the fulfilment of this task but most of the time theses processes cannot be applied directly without any modification.</p><p>This report presents a migration strategy and migration process applied for a real case of an application in a company. The New Object Oriented design of the application and the result are discussed in the following sections of this document.</p>

In addition to storing 70-75% of their data and business logic in legacy mainframe systems, global corporations have countless custom applications and off-the-shelf ERP products residing within their networks. Increasing competition and shrinking budgets have left managers scouring for innovative, cost-effective methods to maximize the potential of these enormous sunk costs. There is, as a result, an overwhelming need to not only web enable these existing legacy assets in order to quickly and cost-effectively deliver data to both customers and business partners alike, but also to amalgamate these disparate systems into a unified, homogeneous, real-time enterprise. Integration efforts to date, focused predominantly on the development of proprietary point-to-point adapters, have unfortunately proven to be a daunting task with countless failed projects and losses in the millions. The advent of XML web services does, however, have the potential to revolutionize existing integration strategies; the cost savings and ease of implementation associated with wrapping virtually all systems, past, present and future, with standardized, code-independent, data-centric interfaces is truly astounding. As the future success of this platform is, however, strictly dependent upon the interoperability of its endpoints, we have proposed several fundamental amendments to the existing flawed WSDL specification. A generic reference architecture, leveraging both this improved web services model as well as established component middleware technologies, is then proposed for the web enablement of legacy assets on an enterprise scale. In order to ensure the adoption of this methodology, a toolkit designed to automate the transformation has also been devised. This new paradigm will not only allow information to flow freely from deep within the enterprise, but will ultimately serve as the cornerstone of a new generation of enterprise integration solutions.

Web forms development for Web based applications is often expensive, laborious, error-prone, time consuming and requires a lot of effort. Web forms are used by many different people with different backgrounds and a lot of demands. There is a very high cost associated with the need to update the Web application systems to achieve these demands. A wide range of techniques and ideas to automate the generation of Web forms exist. These techniques and ideas however, are not capable of generating the most dynamic behaviour of form elements, and make Insufficient use of database metadata to control Web forms' generation and appearance. In this thesis different techniques are proposed that use RuleML and database metadata to build rulebases to improve the automatic and dynamic generation of Web forms. First this thesis proposes the use of a RuleML format rulebase using Reaction RuleML that can be used to support the development of automated Web interfaces. Database metadata can be extracted from system catalogue tables in typical relational database systems, and used in conjunction with the rulebase to produce appropriate Web form elements. Results show that this mechanism successfully insulates application logic from code and suggests that Abstract iii the method can be extended from generic metadata rules to more domain specific rules. Second it proposes the use of common sense rules and domain specific rules rulebases using Reaction RuleML format in conjunction with database metadata rules to extend support for the development of automated Web forms. Third it proposes the use of rules that involve code to implement more semantics for Web forms. Separation between content, logic and presentation of Web applications has become an important issue for faster development and easy maintenance. Just as CSS applied on the client side to control the overall presentation of Web applications, a set of rules can give a similar consistency to the appearance and operation of any set of forms that interact with the same database. We develop rules to order Web form elements and query forms using Reaction RuleML format in conjunction with database metadata rules. The results show the potential of RuleML formats for representing database structural and active semantics. Fourth it proposes the use of a RuleML based approach to provide more support for greater semantics for example advanced domain support even when this is not a DBMS feature. The approach is to specify most of the semantics associated with data stored in RDBMS, to overcome some RDBMSs limitations. RuleML could be used to represent database metadata as an external format.

The aim of the thesis was to develop an algorithm to generate synthetic XML documents to cover the resolution of an XPath query with test cases, with a special emphasis on the ease of configuration. We have also implemented a prototype, optimized its performance and demonstrated its properties by running it on sample data. Powered by TCPDF (www.tcpdf.org)

Title: Efficient Detection of XML Integrity Constraints Author: Michal Švirec Department: Department of Software Engineering Supervisor: RNDr. Irena Mlýnková, Ph.D. Abstract: Knowledge of integrity constraints covered in XML data is an impor- tant aspect of efficient data processing. However, although integrity constraints are defined for the given data, it is a common phenomenon that data violate the predefined set of constraints. Therefore detection of these inconsistencies and consecutive repair has emerged. This work extends and refines recent approaches to repairing XML documents violating defined set of integrity constraints, specif- ically so-called functional dependencies. The work proposes the repair algorithm incorporating the weight model and also involve a user into the process of de- tection and subsequent application of appropriate repair of inconsistent XML documents. Experimental results are part of the work. Keywords: XML, functional dependency, functional dependencies violations, vi- olations repair
