The traditional query module can't satisfy the information system query item's uncertainty due to its limitations in the respect of code mobility,free combination query item according to users' needs and robustness.Based on the research of the characteristics of multifarious information system queries,the paper provides a new function which a dynamic general query module should have.The database ascertains the query key word ,and users combine the query items freely The module adopts ASP.NET and C# as two main instruments,taking the advantage of cross-platform exchanging data transferring parameter by using XML file.In the final part,the paper gives the description of the management of some abnormal process.
