With the rapid development of the Internet and Intranet, the way manufacturing companies approach product development is undergoing significant transformation. Enterprises are increasingly building environments that allow for distributed design and manufacturing, which is a crucial part of computer-integrated manufacturing systems (CIMS). Product design information generated during computer-aided design (CAD) processes must be shared across different departments within a company and between various organizations. For instance, internal stakeholders such as management, marketing, and procurement teams often need to access and review product design data and related documentation. To support this, product design information is typically published through a web server, enabling users to browse it via a browser. This method offers an efficient and accessible way to share information. ASP (Active Server Pages) has emerged as a powerful tool for developing dynamic web pages. It runs on the server side, offering high execution efficiency and easy integration with databases. With ASP, developers can retrieve the latest data from a database without worrying about browser compatibility, making it a versatile solution for web-based applications. ASP operates by generating dynamic HTML content on the server before sending it to the client's browser. The file extension for ASP files is .asp, and these files contain a mix of HTML tags, scripting languages like VBScript or JavaScript, and ASP-specific syntax. For example, HTML code is enclosed in `< >`, while ASP scripts are placed within `<% %>`. ASP provides several built-in objects that help manage interactions between the server and the client. These include the Request object for receiving user input, the Response object for sending output back to the browser, the Server object for managing the server environment, the Session object for tracking user sessions, the Application object for managing application-wide data, and the ObjectContext object for handling page-level tasks. When accessing a database, ASP typically uses ADO (ActiveX Data Objects), which allows it to interact with various databases through ODBC drivers. The process involves establishing a connection, executing SQL queries, retrieving results, and then displaying them to the user. This enables real-time data retrieval and enhances the functionality of web-based applications. The database query system for a cam mechanism consists of two main files: `cad.htm` and `search.asp`. The `cad.htm` file defines the name of the table to be queried, and when a user selects a table and clicks "Query," the selected value is passed to `search.asp`. This file then processes the request, executes the query, and returns the results to the browser. For example, the basic dimensions of a cam mechanism are displayed after a successful query. The `search.asp` script includes a function called `rstotable` that formats the query results into an HTML table, making it easier for users to read and understand. The script also handles different types of queries based on the selected table name, ensuring that the correct data is retrieved and displayed. In conclusion, using ASP for remote database access on the Internet or Intranet proves to be both efficient and practical. It plays a vital role in helping modern manufacturing companies achieve seamless information sharing and collaboration.
