Introduction

PostQuick Computing project for As level Content Subjects Page Number 1. Design * Definition of Data requirements * User interface design * method of data entry * record structure,file organisation and processing * security and integrity of data * system design 2. Implementation(testing) * Hard copy to prove correct Working of system * Hard copy of solution 1. Definition of Data requirements The Following data is required for this PostQuick project * Customer Name * Customer Identification number * Parcel length * Parcel breadth * Parcel height * Parcel weight * Consignment Number * Number of parcels * Description of Parcelsand other required fileds I have used. 2. User Interface design I designed my project on visual basics 6.0, and the benefit I found in Visual Basics as compared to other software was that Visual Basics is user friendly. Anyone can use it by clicking certain buttons, and on the other hand other software packages such as Microsoft Access and Microsoft Excel require a bit of knowledge before using them. To make my own project using visual basics, I first designed my form on the paper, which gave me a rough idea about how my project form would look like. This is also attached with my documentation. ...read more.

It was part of validation of the project that, the minimum weight of the parcel should not be less then 1 kg. If it does then the message box would appear saying that too less weight in the parcel. Second validation was that the weight of the parcels should not exceed 30 kg, if it does then the message box would appear saying, too much weight of the parcel" The third Validation was that the maximum dimension of the parcel i.e. (length + breadth + height) must not exceed 3 m, if it does then the message box would appear saying "too big Parcel to send". The fourth validation was that the maximum weight of consignment must not exceed 200 kg, if it does then the message box would appear saying" too much weight of the consignment" 4. Record structure, file organisation and processing:- The file for the database of the consignments for the Parcel Company is saved as a record structure and saved only for the consignments for one day. It includes the data and information required for the parcels in consignments. It is a record file so it cannot be changed, but the database is changed everyday because each day different consignments are sent to the Parcel Company. ...read more.

Conclusion

An arrow describes the direction of flow of the data. * Structure diagrams-These are a mean of showing the design of a program or a systemic consists of charts showing the system or programs broken down into number of levels. * Hierarchy charts-these can be used to show menu hierarchy or a directory hierarchy * Data model:- * A data model represents the relationship between different parts of a database. It consists of entities (data items) and relationship. The entities are shown as rectangles and the relationship are drawn as lines that connect entities.

The problem maybe that an organisation cannot change instantly to a new method of working as existing records will have to be entered into computer and this may take some time. There are two main approaches to this * Implement the system department by department * Dual run the new system alongside the old system The two databases below are linked to Visual basics6.0 forms 8.Testing Length,width,height,weight Test Results Right/wrong o.25,0.12,0.05,1.5 Works 7.5 pounds Right 1.00,0.60,0.40,15 Works ?? ?? ?? ?? 1 1 ...read more.
