I am building a project titled handwritten signature verification. I am using visual c++ for my project. In the project, I am to do a software to obtain a signature and do some image manipulation to calculate a few values, negative slant, positive slant and its baseline values. Once I got the values I will need to go to the database to get the pre-stored values of that particular customer and compare both of them to see if they match. How am I suppose to build the database system and make it interact with my program. I am also using visual c++ to write the database. Now I can only manage to do a database to store the values. What commands should I put in my software to call the values from the database to be compared and match.
