  • A Reverse Engineering Approach for Migrating Data-Intensive Web Sites to the Semantic Web
    A reverse engineering approach for migrating data-intensive web sites to the Semantic Web Nenad Stojanovic, Ljiljana Stojanovic, Raphael Volz AIFB Institute, Univ. of Karlsruhe,Germany, {nst,lst,volz}@aifb.uni-karlsruhe.de The Semantic Web is intended to enable machine understandable web content and seems to be a solution for many drawbacks of the current Web. It is based on metadata that describe the formal semantics of Web contents. In this paper we present an integrated and semi-automatic approach for generating shared-understandable metadata of data- intensive Web applications. This approach is based on mapping the given relational schema into already existing ontology structure using a reverse engineering process. As a case study we present this style of a schema- and data-migration for our Institute web portal. The presented approach can be applied to a broad range of today's data-intensive Web sites. 1. INTRODUCTION The Semantic Web is one of today's hot keywords. It is about bringing ``[...] structure to the meaningful content of Web pages, creating an environment where software agents, roaming from page to page, can readily carry out sophisticated tasks for users.'' [17]. In order to enable this, web sites are enhanced with metadata that provide formal semantics for Web content. The key technology involved here are the ontologies. The ontologies provide consensual domain models, which are understandable to both human beings and machines as a shared conceptualisation of a specific domain that is given. Using ontologies, a content is made suitable for machine consumption, opposing to the content found on the web today, which is primarily intended for human consumption.

  • Automated Testing of Database Schema Migrations
    DEGREE PROJECT IN COMPUTER SCIENCE AND ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2019 Automated Testing of Database Schema Migrations PETER JONSSON KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Automated Testing of Database Schema Migrations PETER JONSSON Master in Computer Science Date: June 28, 2019 Supervisor: Johan Gustavsson Examiner: Elena Troubitsyna School of Electrical Engineering and Computer Science Host company: The Swedish Police Authority Swedish title: Automatiserad testning av databasschemaförändringar iii Abstract Modern applications use databases, and the majority of them are relational databases, which use schemas to impose data integrity constraints. As appli- cations change, so do their databases. Database schemas are changed using migrations. Certain conditions can result in migrations failing in production environments, leading to a broken database state and testing can be problem- atic without accessing production data which can be sensitive. Two migration validation methods were proposed and implemented to au- tomatically reject invalid migrations that are not compatible with the database state. The methods were based on, and compared to, a default method that used Liquibase to structure and perform migrations. The assertion method used knowledge of what a valid state would look like to generate pre-conditions from assertions to verify that the database’s state matched expectations and that the migrations were compatible with a database’s state prior to migra- tion. The schema method, used a copy of the production database’s schema to perform migrations on an empty database in order to test the compatibility of the old and new schemas. 108 test cases consisting of a migration and a database state were used to test all methods.

All the used materials, references to the literature and the work of others have been referred to. This thesis has not been presented for examination anywhere else. Author: Aleksandr Lapuškin 21.05.2016 3 Abstract Open-source solution for schema and data migration between two PostgreSQL databases A large part of developing new or maintaining existing software is finding, analysing and removing defects, also known as bugs. Sometimes these defects are only reproducible using real-world data or configurations. However, often obtaining or installing this data on a developer’s workstation is difficult to accomplish or requires a custom-made solution for each project. This thesis describes a proposed solution to this problem in the form of a desktop application, which would allow users to easily migrate the structure and data of a single PostgreSQL database instance to another one, requiring minimal configuration to work. A working GUI-based application, providing simple migration functionality between PostgreSQL database instances was written using the Java programming language. This thesis is written in English and is 36 pages long, including 4 chapters, 9 figures and 7 tables.
