Introduction
Solutions to the problem Highfield video store currently uses a paper system to perform all the functions required for this business. Before I reach a decision on how to produce an advanced and improved system to the existing system it is imperative to choose the correct software to overcome this situation. I will need to evaluate and consider the factors that need to be tackled on producing this system by evaluating the end users requirements and expectations f the system to ensure the software chosen has the capability to overcome these requirements successfully and competently. As the company is looking for a more flexible data management system, so a database system is likely to be the right solution. Using Microsoft Access as a solution Advantages: o Microsoft Access is a relational database management system which allows a one to many relationships between tables. Thus greatly reduces data inconsistency and data redundancy. o Uses a familiar interface to perform a range of tasks such as; setting up tables, forms, queries, macros and reports. ...read more.

Also contains macro which can automate a series of commands and functions. o Excel forms can also be customised to satisfy the users requirements with different methods of data entry and appearance of the forms. o Graphs can be created to summarise data in a number of different graphs to allow the data to be more understandable to the user and also produces a professional outlook. Disadvantages: o The recording of macros can be problematic as it is easy to make a mistake and the whole process needs to be repeated again. This requires an experienced person with sound knowledge of macros and formulas to perform this task. o Microsoft Excel is a spreadsheet package and doesn't features such a relational database which are available in Access. Therefore data and tables need to be entered again leading to unnecessary data redundancy and data consistency. o Creating and editing macros needs to be done via Visual Basic Editor program in Excel. Users of this program need to be experienced in using this program as the macros commands need to be programmed by the user. ...read more.
Conclusion
o Microsoft Access can provide customised reports to summarise a set of data. Access allows data to be brought together in a report which can be tailored to the user choice. So a professional output which is in line with the companies image can be produce whereas as other software such as Microsoft Excel would not have the capacity to do this. Data would need to be summarised into graphs and is difficult to suit the companies image so the output and interface of a system using this software would need be as professional compared to the software being use to created this system. o Access has the capability to update records in any table by setting up queries to update the necessary records. This will lead to more consistent data is it is more likely to be update and accurate. o Data and information that needs to be stored can be done so more easily due to the set up of the system. Tables are clearly defined and related, which is not the case with other software such as Microsoft Excel as relationships between tables cannot be emplaced. ...read more.
