s needs, there are some problems as follows are needed to notice:?The demand should be confirmed by way of the document.?The feasibility and price of their demands are informed to the demand side after effective analysis and discussion. module designThe demand report will be organized as some modules according to the principles of high cohesion and low coupling and related experience by the website developers. design and implementationIt contains the demand analysis, the concept design, the logical design, the physical design, the system implementation, the operation and the maintenance. The following problems should be paid attention to during the database design and implementation:Database security [5]: The database is the core of website, in which the data security is very important. The damage and lose or illegal duplication of data can cause a lot of trouble, moreover the mistake is very difficult to restore. MYSQL security measures are as follows:?Account security: Each account of MYSQL is posed of user name, password as well as the position, which includes reasonable rights and security check. The reasonable rights demand that there are different rights for the different account and as identical user there are different rights for different database or data sheet. There are three different security checks in the MYSQL: register confirmation, authorization, access control.?Stored data encryption [6]: for the massive information in application program, you only want to encrypt a very small part of it, such as user password. These passwords should not store in the form of plaintext but encryption in the database. In general, the sensitive data is encrypted by Hash algorithm in most DBMS including MYSQL.The database character set and coding [7]: The default code used in web server software installed, like Apache, is not UTF8. The webpage is normally browsed when we input data into table coded in UTF8, but Chinese in phpMyAdmin turns into messy code. The solution is that the default code in MYSQL turned into UTF8 or the data code (UTF8) is assigned when the database is connected[8]. Functional Module ImplementationA few codes, detailed annotation and standardized writing are demanded during functional module implementation. The goal is high reusability, high reliability, efficiency, high security and so on. STUDYThe authors developed the consult website (ZhuoQi, domain name address is ) based on PHP. ZhuoQi mainly includes nine modules, such as the retrieval module, the expert consult module, the
