PostQuick Computing project Essay

I designed my aver on optical basics 6. 0, and the benefit I found in Visual basics as comp bed to opposite softwargon was that Visual Basics is user friendly. Any genius gutter use it by flicking genuine buttons, and on the other hand other software packages such as Microsoft get to and Microsoft Excel require a bit of knowledge before using them. To make my own figure using optical basics, I outgrowth designed my socio-economic class on the paper, which gave me a rough idea about how my project realise would panorama like.This is alike attached with my documentation. I designed my project by prototyping, and do my form using these things A set of screen that shows the user what male monarchfulness be possible A frame with limited functionality An existing system that might be modified For my human-computer interface (HCI), I used graphical user Interface (GUI) which is used in Microsoft windows . My form had certain buttons which could be used by clicking the mou se and nigh text boxes in which instruction was entered using keyboard.I think that the advantage of this fictional character of interface is this that It is blowsy to use In my form no one needs exceptional instruction The disadvantage of GUI is It uses a lot of affect index exit It requires good graphical display It uses a lot of processing power It uses a lot of memory and disk space 3. Method of information Entry, including Validation As said before that my form had certain buttons and these buttons could be used by clicking the mouse and some text boxes in which info was entered using keyboard.I declared each information type with certain specific data type, and checked that if I entered wrong data type past it would not work. The method of data entry is also shown in implementation. The program contains three forms. The main form, which is named gossip form, is the start-up form. This is the data entry form for all the data, which is entered for a particular assi gnment. The method of entering data is as follows. Consignment No These are self-generated. Numbers, its enabled property is false. User has no control on entering its data.Customer Name destination and client woo bequeath be entered in respective columns. Afterwards the information of the first megabucks of the load will be filled (i. e. the whole form will be filled). If there are more then one piece of land required to be entered for the same consignment then add up new parcel button is pressed for the parcel, and after each parcel entry of the consignment data entry complete button will be pressed For a separate consignmentnew consignment button is required to be pressed.It was part of validation of the project that, the borderline weight of the parcel should not be little then 1 kg. If it does then the nub box would appear verbalism that too less weight in the parcel. Second validation was that the weight of the parcels should not get over 30 kg, if it does then the message box would appear saying, too much(prenominal) 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 despatch.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 brass 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 pratnot be changed, but the database is changed everyday because each day different consignments are send to the Parcel Company.The database is linked with Visual basics form, and the file of database is stored as a Microsoft access file. F or the backup the file is saved in the floppy so if the actual program in the processor is altered, we can bring back the old one. There are four files that I used for my project one was the form file, named as input parcel, and two forms were for the price list, the Access file linked to database, named as, payslip database which has two databases linked to each other.The actual processing carried out by the program is arithmetic operation, in other lecture calculation is being carried out, but the bigger companies can use clock SYSTEM, which would be more economical for them. 5. aegis and integration of Data Security is the most important thing, because if your data is not secured properly from unauthorised workforce then anyone could change your data and could change your project I consequently kept the project under a password So no one could change or alter my project.If someone did change my database then I could use my backup to restore it from the floppy in which Ive ke pt the backup file so if the actual program in the processor is altered, we can bring back the old one. I also protected my data, by using the menu button in the visual basics. If you go to the text box, u click on it and then click text box protect enable force and in this way I can protect my text. I also made indisputable that when data is entered it is entered accurately and I checked that when I was entering data, no one enters anything. 6. frame design-For documenting my project I used arrangement flow charts-It describes the flow of data around the system. This method uses rectangle to denote some process that takes place, as descriptive symbols to describe the storage or input/output of data. An arrow describes the direction of flow of the data. Structure draws-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 pecking or der or a directory hierarchyData 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.

Implementation The project that I support made for PostQuick Company can be implemented either as a whole or in parts.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 section by department Dual run the new system alongside the old system The two databases below are linked to Visual basics6. 0 forms 8. examen Length,width,height,weight Test Results Right/w rong.
