Information Retrieval System Centered on RDBMS: A Survey

Relational Database management systems (RDBMS) are extensively used software products in numerous types of systems. As we all are familiar with natural language which is the main communication means for humans, but this causes it not easy to handle damaged information. Earlier, research work while querying data from relational databases frequently goes through one of two ways: the keyword-based approach and the structured query approach. Both the ways have their recompense and disadvantages. The structured query approach, while expressive and powerful, is not easy for naive users. The keyword-based approach is very friendly to use, but cannot express complex query intent accurately. This paper emphasis on Natural Language based query processor and we have discussed different approach of information retrieval system. Natural Language Processing is becoming more important in the field of Human Computer Interaction.
