title: Can we say that a database is a webservice that works with data on filesystem?
body: <p>These days, i made a webservice, that extracts data from files, sort, search etc.. and retrive data to the request sender.</p>
  
  <p>Then, i noticed that it was like how a database works, it take a "query" which is equal to a string with keywords in it and then filter data on files, based on the request parameters. </p>
