Thesis (MEng)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The logical allocation of tasks in engineering offices currently relies heavily on the experience and intuition of project managers. In large scale projects the complexity of the task allocation procedure exceeds the capacity of human intuition, and a systematic technique is required to aid project managers in assigning tasks to individuals. In this project such a systematic technique is modelled and implemented using the Java programming language. An equation was developed to calculate an individual’s workload, and used in conjunction with other criteria to intelligently and systematically select an optimal individual to complete engineering tasks. The software solution is network-based, and also aims to aid project managers in various managerial duties. / AFRIKAANSE OPSOMMING: Die logiese toekenning van ingenieurstake steun tans swaar op die ervaring en aanvoeling van projek bestuurders. In grootskaalse projekte is die kompleksiteit van die taak toekenningsproses veel groter as die kapasiteit van menslike intuïsie. Dus word ‘n sistematiese proses wat projek-bestuurders kan help met die toeken van take aan individue vereis. In hierdie projek is so 'n sistematiese tegniek ontwikkel en geïmplementeer met behulp van die Java-programmeringstaal. 'n Vergelyking is ontwikkel om 'n individu se werklading te bereken en is in samewerking met ander kriteria gebruik om take intelligent en sistematies toe te ken. Die sagteware is network en databasis-gebaseerd en kan ook gebruik word om projek-bestuurders te help met verskeie bestuurspligte.

The Web Based Query Optimization Simulator (WBQOS) is a software tool designed to enhance understanding of query optimization with a Relational Database Management System (RDBMS). WBQOS allows the user to visualize and participate in query optimization, which enhances the learning process.

This project is a movie theater order system. This system allows people to get movie information and purchase tickets on the Internet. This project is based on a Model-View-Controller (MVC) architecture, which introduces a controller servlet to provide a single point of entry to the web system and encourages more reuse and extensibility of the code.

The main purpose of this project is to provide an easy-to-use interface for students and faculty members to interact with each other during the course of a student's internship class.

Text in English / Although research paradigms and philosophies are highly regarded as frameworks and guides for choices of methods, application thereof is not evident. One of the reasons for the relatively limited application is the complexity and understanding surrounding paradigms and philosophies, making it hard for scholars to determine their stances and implications. This study describes a model for automatically predicting peoples’ paradigm and philosophical stance, including meaning, and their impact on research by helping the user determine the paradigm and philosophical stance closest to their beliefs. Paradigm and philosophical attributes are automatically derived from a set of structured questions that use information matching techniques. The development of a model for Research Paradigm and Philosophy Index (RPPI) follows a two-phase approach. The first phase involves automatic extraction of key indicators from a composed database that utilises an indexing scheme with different philosophies and associated implications. The second phase applies a matchmaking technique that automatically draws information reflecting the user’s attribute. This type of technology exists, but mainly in the dating and career matching fields. None exists for research paradigm and philosophical stances. The prototype system was designed and implemented to serve as a proof of concept, and was developed in Angular, using the Visual Studio Code, and Java, using Eclipse. The database was created using MySQL. The prototype system was designed and implemented to serve as a proof of concept due to the Intellectual Property nature of the product. Usability testing was conducted and results show that the participants agreed the system was simple, straight-forward to use, quite user-friendly and easy to learn, with easy navigation through menu items. / Computer Science / M.Sc.

The purpose of this project is to manage restaurants using a software system called GRIPED (Get the Right Price Every day). The system is designed to cover quality control, food cost control and portion control for better management of a restaurant.

Approved for public release; distribution is unlimited / Handheld devices have evolved significantly from mere simple organizers to more powerful handheld computers that are capable of network connectivity, giving it the ability to send e-mail, browse the World Wide Web, and query remote databases. However, handheld devices, because of its design philosophy, are limited in terms of size, memory, and processing power compared to desktop computers. This thesis investigates the use of Data Flow Query Language (DFQL) in querying local and remote databases from a handheld device. Creating Standard Query Language (SQL) queries can be a complex undertaking; and trying to create one on a handheld device with a small screen only adds to its complexity. However, by using DFQL, the user can submit queries with an easy to use graphical user interface. Although handheld devices are currently more powerful than earlier PCs, they still require applications with a small footprint, which is a limiting factor for software developed. This thesis will also investigate the best division of labor between handheld device and remote servers. / Sergeant, United States Army

XML is an emerging standard format for data on the Web as well as in business applications. In order to store and access this information in an efficient manner, database technology must be utilized. A relational database system, the most established and mature technology for query processing and storage, creates a strong foundation for such an XML data management system. However, while relational databases are based on SQL queries, the original user queries are written in XQuery, an XML query language. This XML query language has support for order-sensitive queries as XML is an order-sensitive markup language. A major problem has been discovered with loading XML in a relational database. That problem is the lack of native SQL support for and management of order handling. While XQuery has order and positional support, SQL does not have the same support. For example, individuals who were viewing XML information about music albums would have a hard time querying for the first three songs of a track list from a relational backend. Mapping XML documents to relational backends also proves hard as the data models (hierarchical elements versus flat tables) are so different. For these reasons, and other purposes, the Rainbow System is being developed at WPI as a system that bridges XML data and relational data. This thesis in particular deals with the algebra operators that affect order, order sensitive loading and mapping of XML documents, and the pushdown of order handling into SQL-capable query engines. The contributions of the thesis are the order-sensitive rewrite rules, new XML to relational mappings with different order styles, order-sensitive template-driven SQL generation, and a proposed metadata table for order-sensitive information. A system that implements these proposed techniques with XQuery as the XML query language and Oracle as the backend relational storage system has been developed. Experiments were created to measure execution time based on various factors. First, scalability of the system as backend data set size grows is studied. Second, scalability of the system as results returned from the database grows, and finally, query execution times with different loading types are explored. The experimental results are encouraging. Query execution with the relational backend proves to be much faster than native execution within the Rainbow system. These results confirm the practical utility of our proposed order-sensitive XQuery execution solution over relational data.
