Engineering Question Bank System Design and Implementation
BASE. RECORDSOURCE to achieve the search for purpose. DATABASE. RECORDESOURCE SE-LECT statement is based on search criteria, so the variable should be assigned into the SE-LECT statement form. DTSELECT = \Search for questions after the general conditions. The DATABASE. RECORDSOURC refresh the search questions. That is, manual control by the selected conditions generated papers. FORM5 interface shown in Figure 4, the text box TEXTBOX the TEXT1. TEXT for the item ID. Figure 4 Test preview and generate Fig. 4Previewandgenerationofexamination-questions RICHTEXTBOX rich text box to display the current ID set. Number of questions. Data control and a text box command button with the database TEXTBOX COMMAND1. CAPTION = \CAPTION = \CAPTION = \CAPTION = \Volume 22 RICHTEXTBoX in. Questions in the previous DSELECT choose not to join in, but added to the C0MBO in. After COMBO choice response when triggered by COMMAND2 Questions DSELECT adding a condition is found DSELECT conditions DATABASE search all kinds of questions a single species of test questions, which can achieve the kinds of questions the entry requirements of a single species. Select an item, first determine whether the selected questions in this type of exercise completed, if the election finished,[link widoczny dla zalogowanych], will show \If selected, will show \When asked to enter other kinds of questions you can choose to COMBO in the entry of other kinds of questions to test questions,[link widoczny dla zalogowanych], but also realized the kinds of questions, scores, etc. inserted, and the item information (ID number, question type, score) storage in the array. By COMMAND3 (answers questions generated) key, according to information from an array of library answers questions with detailed answers are generated and marking of examination papers. 4 Conclusion test database system using a reasonable method of database design, the use of object-oriented programming techniques to achieve real-time database management questions and examination papers, answers to the control output, to better ensure the effectiveness of the system,[link widoczny dla zalogowanych], scalability , openness,[link widoczny dla zalogowanych], portability. At the same time provide a convenient and efficient for teachers working platform, reducing the work load, has a strong practical value.
