Based On The Keyword Query Database Search Engine System Design And Implementation

Now the society is more and more high prevalence of Internet, more and moreusers through the Internet for the exchange of information and interaction, presence ofinteractive information must use the database. Access the data in the relation database isthe main interface is a traditional SQL. But, for some inexperienced users, the study isvery complex learning the syntax of the SQL is a very troublesome thing. No need toknow the object being queried the underlying structure. But if we are to achieve the keyrelational database information retrieval, users do not need any underlying databaseschema and SQL language, can also use a search engine to obtain the relevant data inthe database. This thesis focuses on is how to achieve using a keyword query databasesystem. Introduces in detail the relationships between the tables in your database, toachieve query stored procedures and functions. The system according to the keywordsattribute is divided into text query and attribute query, in these two kinds of querypattern is divided into single table query, query and traversal search. Single table queryis directed to a specific table query, query by matching table query, traversal of all tablesin the database and all properties.In this thesis, the last part of this thesis the system has done to sum up the work,and expounds the further the system is complete and expand the work of some of the.
