    Analysis, design and implementation of a computer-based information system for Dairo air services handling limited
    (Kampala International University, School of Computing and Information Technology, 2009-07) Nakigozi, Linda
    Standard of flight handling depends a lot on flight information management. However, DAS Handling’s current system is not efficient (manual data entry is slow and prone to errors) and is unreliable. DAS Handling Ltd needs a fast and reliable means of flights’ data circulation. Information on flight handling should be easily accessible by all parties involved in order to have quick turnaround of flights. this study therefore aims at identifying means that can minimize additional costs that may arise due to delay of flights on ground, and provide complete and consistent information about activities taking place in all departments at all times based on a variety of concurrent data sources. The study is a non-experimental research and followed a case study design (in-depth information about a limited number of subjects, and may produce new insights that generate additional studies, according to yin (1994); specifically an exploratory case study (fieldwork, and data collection may be undertaken prior to definition of the research questions and hypotheses).

    Developing framework for adopting e-learning pedagogical approach in Higher Education : a case for Makerere University, Kampala, Uganda.
    (Kampala International University, School of Computing and Information Technology, 2012-10) Humphrey, Mukooyo Geoffrey
    The overall objective of this study is to investigate the challenges of adopting e-learning pedagogical approach in higher education in higher education institutions in Uganda. The descriptive research design method was employed in this study. It involved using the questionnaires in collecting data from the respondents. The quantitative research design was used in gathering data on cases of efficiency in accessing, retrieving, securing, storing, registering and disseminating information the departments. Furthermore, this research collection technique was used because it was flexible and reliable method of data collection. The sample size 171 respondents from Makerere University, Kampala, Uganda. The researcher used simple random sampling which was a type of sampling technique that allowed researchers to collect data in which each element in the population has a known and equal probability of selection. This technique was convenient in order to achieve the research objectives because the respondents would have the same chance to be in sample. The research findings were that the students and lecturers could use the e-learning platform without any hindrance and online learning required Internet access and transmission of multimedia materials required high bandwidth. Universities could tackle some issues themselves. They could come together in order to buy bandwidth in bulk so as to reduce costs. To gain this kind of negotiating power, institutional leaders and IT departments must cooperate. Institutional managers would also have policies for using bandwidth sensibly by defining acceptable use. The recommendations are that use of new collaborative technologies required team work more than we were used to, in order for eLearning courses to produce an outcome that was competitive in the global employment market; universities need to invest carefully in online courses and before commencing an eLearning program, capacity analysis needs to be done first

    Query Optimization and Database Tuning In Free and Open Source Software Databases and Proprietary Databases
    (Kampala International University, school of computer science, 2006-10) Suleiman Kedir, Nebi
    There are many factors that affect the performance of databases and database throughput. However, more often than not, these factors are not critically analyzed and assessed by the Database Administrator or by any person charged with the responsibility ot overseeing the day-to-day running of the database. Critical and complex Queries are needed frequently to be executed. Most of the times these queries are not tuned effectively to get maximum out put, so it Is needed to tune them according to the environment in which they are used. There is therefore a need to determine the performance indicators for the database when it comes to query optimization and database tuning. These indicators are also influenced by the platform on which the database is to be run- proprietary or open source. This research therefore tries to carry out a comparative study and analysis of the query optimization and database tuning on the two platforms windows and Linux. The major findings of this research Is that MySQL Unux database runs faster than MySQL windows and Oracle windows when creating tables whereas the execution time is faster in oracle on windows when a query contains a join. This is found to be based on the Cost-base Optimization (CBO) execution plan and path taken by the query optimizer which is found to be more complex in Oracle than in other databases.
