This study has made an attempt to address the major issues that should be considered whenrnprogramming application programs that run in a network environment. The implementationrnof these issues has also been demonstrated through the enhancement of the LivestockrnInformation Management System (LIMS), a software developed by the InternationalrnLivestock Research Institute (ILRI) the former International Livestock Centre for Africarn(ILCArnDuring the course of this study, LIMS has been enhanced and the following facilities havernbeen incorporated to the system: 1) the five modules of the LIMS software were integratedrnso that all the modules could be accessed from a single user interface menu; 2) LIMS wasrnenhanced for simultaneous access by various users in a network environment; 3) passwordrnprotection was added for options that require special security due to the effects of suchrnprocesses on the data set; 4) a semaphore protection means was developed for memoryrnfiles which are not supported by the locking provisions of the programming language used;rn5) record and file locking were implemented for keeping the integrity of the data files; 6) arntime duration checking was added to allow for several attempts that fail on the first trial;rnand 7) a sure write procedure has been implemented so that changes are made visible to allrnusers of the shared data.rnThe study has also made recommendations on the need for rigorously testing of the currentrnwork, addition of on-line help facility, and system utilities for better use of the software.
