By using protege can we store & retrieve data's like we doing it on relational database? <p>Hi I very new to semantic web and <code>Protege</code>.</p> <p>Can we store and retrieve data in <code>Protege</code> like we do in relational database? Or can we manipulate only models? if yes, do we need RDBMS for storing data and use <code>Protege</code> to manage the relationship?.</p> <p>Can we use protege as replacement for Mysql Database to store and retrieve information? </p> <p>OR I am completely wrong about what is protege?</p>
