Abstract
Abstract- The main target of the wrk described in this paper is to provide a powerful approach for naiLe users to search structured databases. Such a study is necessary especially to satisfi web users who expect the abilify to access all web contents in a unified way, regardless of the structure of the available information. Given a set of distributed structured databases and a que?y which consists of a set of keywords connected by logical operators, the approach proposed in this paper adapts both web text files search techniques and information retrieval techniques to rank the existing databases based on their relevance to the posed query. For each keyword, the user specifies a level of search, which may be column, record, or table. We developed an estimation method with statistical foundations to estimate the usefulness of individual relational databases. The system gives a hint of what databases might be useful for the user's query, based on wrd-frequency information kept for each database. Some experiments have been conducted to demonstrate the efectiveness of the proposed method in determining promising sources for a given query. As nai've end-user satisfaction is a main target and motive. w developed a prototype system with a user friendly web-based interface that accomplishes our goals in a simple andpowiful wy. 1
