This paper presents a careful study and analysis of an existing manual sales and inventory control system of a pharmaceutical store and aimed at designing and developing a computer-based system in order to increase the efficiency and accuracy of the business operations of the pharmaceutical store. The study was carried out to reduce the problems of inconsistency and inaccuracy of sales and drug data inherent in the existing manual system of the pharmacy. An analysis of the current manual system was done to get a better understanding of the system. The Rapid Application Development (RAD) methodology was used in this work to implement an iterative program which is suitable for stand-alone applications that can be updated from time to time as may be required by the computer -based system. Testing was done in every phase of the development life cycle to ensure that the new system works properly. The software was developed and implemented using Visual Basic 6.0 programming language and Microsoft Access for the database platform. The software developed provides alert of every expired drug and minimum quantity of each drug available in stock. Other activities such as product sales, drugs and users registration, and periodic reports generation can also be carried out with the new system.

The purpose of this research study is to examine the impact of Computer Studies among teachers and students of secondary schools in Umuahia North Local Government Area of Abia State, especially as it affects the teaching and learning process. The authors adopted a descriptive survey design for this study using four research questions which were formulated based on the purpose of the research. The results of the study indicate that Computer Studies has positive impact in the teaching and learning process in secondary schools in Umuahia North Local Government Area of Abia State, Nigeria. From the findings, the computer literacy level of the students was found to be low while that of the teachers was slightly higher than that of the students. The results of the study also show that equipment and infrastructure such as computers and other information and communication technology (ICT) facilities are also needed in schools to facilitate the acquisition of basic computer skills among teachers and students in secondary schools and thereby increase their computer literacy level.
