Systems Analysis for Unique Travel.

Extracts from this document...

Introduction

Systems Analysis for Unique Travel. Identification of problem to be solved Unique Travel currently stores information on paper and deals with between 0 and 10 customers a month depending on the time of the year. The information is currently held in a manual filing system. When the manager Jeenal Shah, set up Unique Travels fifteen years ago this seemed to be the logical choice. At which time Unique Travels sphere of influence only spanned as far as its local area Palmers Green with between 0 and 32 customers a month. As time passed the number of customers increased, the manual system became slower and subsequently inefficient. With a decrease in the ability to keep up with competition, the business has suffered serious losses. With the ICT world changing Jeenal has finally decided to change the system from a paper-based system to a computer-based system. My task is to create a system that will help the worker of Unique Travels cope efficiently with the large number of customers. At this stage I have spoken to the manager of the store and noted down some of the limitations of the old system and the core requirements of the new system. Jeenal Shah told me that the system should be able to work with minimal amount of data input, holding list of customers in a fast retrievable form. The system should be able to print report in the form of receipt. I have also written to other travel agents asking about their own computer system. Analysis of the problem including research. In order to fully maximize the efficiency o my question I decided to talk to two different people. I feel that firstly I was to interview Jeenal Shah who is backing the project and uses the system. I also felt it necessary to talk to interview the user of another Travel agent on the other side of London who already Implement a Travel agent booking system. ...read more.

Eve proved to be helpful but not as helpful as I would have liked. He seemed fairly out of touch with his system. I found out that Mr. Eve feels that the travel industry will not expand. This is very helpful in case I decide to use a fixed number of records for the current system. This will give me a good estimate for the maximum number of records I will have to create. The interview also helped me to see what different fields I will use, such as flight number, name and so on. Mr. Eve also stressed the importance of testing although I feel that the major crash like the reported by Mr. Eve is unlikely although through testing will be carried out to iron out any problems. The method of dealing with cancellations by deleting them seems responsible. Although Jeenal reported some problems with cancellations in his original system I fell that was mainly due to his disorganization of his data. I feel that with a well-organized system I can keep problems with cancellations down to a minimum. Another reason for using this method of deletion rather than leaving a flag will not only save space in the system but seeing the time scale I have this seems the most feasible method of dealing with cancellations. New system Requirements From the analysis I have gained a better knowledge of the system I will have to create. I feel that the system will be a menu-based system using numbers to go to the next menu, the design will be modular. The system will have to be divided into two main parts. This will be firstly for flights and secondly for booking. Both sections will have the ability to add, delete and edit a file. The booking section will have to also be able to produce a ticket and both sections will allow the options of viewing all files. ...read more.

Conclusion

* The number of seats. * The date of departure. The addition stage will again check that the status of the file is empty before adding. For deletions editions and finding of files the system will check that the status of the file exist and check that the status of the file is not empty. The demands that the system will make will be clear and straight forwards to void any confusion. The system will also ask the user whether he/she us sure before deleting or editing a file. Data organisation and detailed specification of processes required. For this system there are many different type of file organisation that could be used. Ideally I would like to use an Index Sequential organisation method. This would appropriate as I would be bale to search through the system both sequential and directly. As it is extremely difficult to create an index sequential system using Pascal, I am left with two possibilities. Either a sequential filing system, which would search through each record or direct. I feel that I will have to use a direct method for example giving each customer a Booking number and using this number as the address in file. For example booking number 40 would be stored in record 40. There are some clear problems with creating a system using this method, as it would be hard for the user to remember the booking number of a specific customer and to find information on that customer. The option here is to use a hashing algorithm allowing for the possibility for collision. This is possible solution yet keeping in mind the amount of time I have for this project I feel that another solution is better. I can use direct access for additions and search for a combination of the surname and name for searching. I could do this by using (IF, AND, THEN) commands in Pascal. I could then give the user the choice of searching for a specific customer by either the booking number or by their name. Software Development Top Level Design For this 1 ...read more.
