General description
Databases and information retrieval are two areas that have been developed separately. They have focused on different areas of application and, consequently, have given emphasis to different methodologies. Specifically, in databases, we pose queries to data with a particular schema, using an algebra, and care about the accuracy of the queries results, while in information retrieval, we mainly focus on queries, expressed with keywords, on free text documents and on how to rank the queries results based on statistics and probabilities. Nowadays, there are many applications that require the concurrent management of structured and unstructured data, so necessary shows the integration of these two works.
