Král, Michal ; Galamboš, Leo (referee) ; Pokorný, Jaroslav (advisor)
Databases and web are two environments, where searching is used the most. In addition one group of developers draw on the experience of the other one in solving a lot of problems. In majority of projects, both sources of information stay isolated and synchronous convey from both is rather exception. This dissertation follow integration of internet searchers directly into SQL queries. Besides partly analysing papers connecting both subjects, it describes technical aspects of this connection, including method of asynchronous iteration. The gist of this paper lay in realization of three functions, which call web searcher and at the same are suited for use in DB queries. Selected functions are www_rank, which returns relevancy of phrase, then it is www_near, which returns relative relationship of two phrases and the last one is agregation function www_best_address, which returns the best common link for group of phrases. For this purpose we chose database server Oracle 10g and Jyxo.cz web searcher.
