    Development of an interactive e-learning Management system (e-LMS) for Tanzanian secondary Schools
    (University of Dar es Salaam, 2011) Kalinga, Ellen Ambakisye
    E-Learning defined as the use of information and communication technology (ICT) for supporting the educational process, has motivated Tanzania to apply ICT in its education systems. Tanzanian secondary schools which are geographically and socially isolated face a number of problema, including a way to get learning materials. The impact of these problems is poor performance in National Examinations. This poor performance however is most noted in science and mathematics. The problem in getting learning materials can be reduced by employing ICT. This research developed an interactive e-learning management system (e-LMS) to be used by Tanzanian secondary schools. Tanzania Secondary Secondary Schools e-Learning (TanSSe-L) system is the name adopted for an interactive e-LMS developed. The research is aimed at supporting teaching and learning functions by allowing for the creation and storage of learning materials, making them available, easily accessed and sharable by student from different secondary schools in Tanzania. It is a context-driven research work of knowledge production in a specific context for application. Initially, the research work focused on two selected pilot schools; Kibaha Secondary School and Wall-ul-Asr Girls’ Seminary in Kibaha town, Pwani region. Features of the TanSSe-L system represent the standard form of any secondary school registered by the Ministry of Education and Vocational Training. The development of the TanSSe-L system made use of software engineering discipline. The research used Unified Modelling Language (UML) and integrated Object-Oriented System Analysis and Design (OOSA&D) and Model Driven Architecture (MDA) to address the system Development Life Cycle (SLDC) in a systemic way. UML, design class diagram (DCD) is a platform independent Model (PIM) that was transformed into a platform specific model (PSM) in MDA for implementation. Implementation made use of open source LMS to help generate a timely solution to TanSSe-L system development. In this specific context, focus group discussion as inspired by action research methodology was used. The research evolved into a triple helix process in close cooperation with other stakeholders. Finally, it is considered that replication and mirroring will make learning materials highly available to end-users.

    Information technology (IT) feasibility study for Tanzania postal bank (TPB)
    (University of Dar es Salaam, 2002) Kalinga, Ellen Ambakisye
    Computers have become part of the normal office landscape for many years, since computer knowledge started. Many office functions have been converted from paper to electronic form. Centralized databases have been created. Computer networks have been developed so that users at one computer can store and retrieve data on another computer in a centralized area. This centrally stored data can be shared among multiple computer users using data communication networks. These and many other advantages, make the data communication network to be the nerve of many business operations. The primary objective of this dissertation was to conduct an Information Technology feasibility study at Tanzania Postal Bank Limited (TPB) so as to establish the status of .IT and to propose a way forward. The study found that TPB has Local Area Networks (LAN) at its current few branches, but these LANs are not interlinked in any way. This drawback makes the bank to conduct inter-branch operations manually. The dissertation concentrated in this particular area of finding a way of creating inter-branch Wide Area Network, which is the key for data communication. The dissertation focuses on analyzing different ways used to create WAN and finding out different types of network services offered by data communication operators in Tanzania. Later the dissertation comes out with a proposal and design of a suitable way of creating WAN for TPB in particular. The proposed method is justified in terms of: Cost, system performance (stability and speed of operation) and maintainability, easy in network extension, technical personnel support and its security. The dissertation also came out with the proposed means of securing: hardwares, data communication network and data to be transmitted, since security in banking institution is of no compromise.
