sql server - How can I store SQL data with read-only access to one DB? -


i have issue i've never encountered before , i'm not entirely sure how proceed. i've been asked write c# winform application. have read access sql database contains 99% of information application requires. there 2 or 3 pieces of information need stored can't store in sql database i'm not allowed insert or add additional fields.

e.g. sql database might contain table following fields software requires: name address emailaddress

but, in hypothetical example, need store phone number, can't store in sql database.

so can think of few options, not sure best solution.

  1. store additional data in file of kind in installation directory;
  2. create new sql database can write mirrors data read-only database on schedule ensure data accurate across both platforms. database application use 100% of time;
  3. create 2nd sql database stores additional bits of data, meaning application query both sql databases perform functions.

weird, huh?
