PostQuick Computing project Essay Example for Free

PostQuick Computing travail EssayI designed my view on optical basics 6. 0, and the benefit I found in Visual Basics as comp ard to different software was that Visual Basics is exploiter 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 apply them. To make my own project using visual basics, I first designed my operate on the paper, which gave me a rough idea about how my project jump would look like. This is also attached with my documentation. I designed my project by prototyping, and make my form using these things A set of screen that shows the user what might be possible A system with special(a) functionality An existing system that might be modified For my human-computer interface (HCI), I used graphical user Interface (graphical user interface) which is used in Microsoft windows . My form had certain buttons which could be used by clic king the mouse and few school text stripees in which data was entered using keyboard.I think that the advantage of this type of interface is this that It is idle to use In my form no one needs special instruction The disadvantage of GUI is It uses a lot of touch on power It requires good graphical display It uses a lot of processing power It uses a lot of memory and disk space 3. Method of Data 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 data was entered using keyboard.I declared each data type with certain detail data type, and checked that if I entered wrong data type then it would not work. The mode of data initiation is also shown in implementation. The program contains three forms. The main form, which is named input form, is the start-up form. This is the data entry form for all the data, which is entered for a particular assignment. The method of enterin g 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 leaf node address will be entered in respective columns. Afterwards the information of the first helping of the load will be filled (i. e. the whole form will be filled). If there are more(prenominal) then one parcel needed to be entered for the same consignment then add overb senior 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 minimum load of the parcel should not be slight then 1 kg. If it does then the message box would appear manifestation that too less burthen 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 transcription 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 several(predicate) consignments are sent to the Parcel Company.The database is linked with Visual basics form, and the file of database is stored as a Microsoft doorway file. For the back upup the file is saved in the floppy so if the actual program in the mainframe computer is demasculiniseed, 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 devil 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 words calculation is being carried out, but the bigger companies can use CLOCK SYSTEM, which would be more economical for them. 5. Security and integration of Data Security is the most important thing, because if your data is not secured justly from unauthorised hands then anyone could change your data and could change your project I therefore unbroken 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 kept the backup file so if the actual program in the processor is altered, we can bring back the old one. I also cling toed 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 sure that when data is entered it is entered accurately and I checked that when I was entering data, no one enters anything. 6. governance design-For documenting my project I used System 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/ produce of data. 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 follow of levels. * Hierarchy charts-these can be used to show menu power struct ure or a directory power structureData 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.

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.
