title: What file format can be use to save/access data instead on database
body: <p>There is a situation in my company where we are developing a light weight .net web application with least dependencies. Application will be used hosted on client server. However there will not be any internet connection and they will use application locally.</p>
  
  <p>We do not want any type of database installation on client machine. We want to keep it as simple as possible on client side. for this purpose we want to save/access data from file, as data on client side will not exceed more than 100 000 rows. We are also concerned about the speed for accessing data.</p>
  
  <p>Here I want to ask how the data should be saved in file so that it can be accessed fast? What file format should be?</p>
  
  <p>Whether I can use any db file which does not require any database installation on client side.</p>
