The necessity of relational databases grows very larger .Relational database is structured to recognize relations between stored items of information. Extending the keyword search to relational data has been an active area of research. Many techniques have been proposed but all those techniques suffer from lack of standardization. Lack of standardization results in contradictory results. Keyword queries on databases provide easy access to data, but often suffer from low ranking quality, i.e., low precision and/or recall, as shown in recent benchmarks. It would be useful to identify queries that are
likely to have low ranking quality to improve the user satisfaction. For instance, the system may suggest to the user alternative queries for such hard queries. In this paper, we analyze the characteristics of hard queries and propose a novel framework to measure the degree of difficulty for a keyword query over a database, In summary, our work confirms previous claims regarding the unacceptable performance of these search techniques and underscores the need for standardization in evaluations
