 <p>Django web applications access and manage data through Python objects referred to as models. Models define the <em>structure</em> of stored data, including the field <em>types</em> and possibly also their maximum size, default values, selection list options, help text for documentation, label text for forms, etc. The definition of the model is independent of the underlying database — you can choose one of several as part of your project settings. Once you've chosen what database you want to use, you don't need to talk to it directly at all — you just write your model structure and other code, and Django handles all the dirty work of communicating with the database for you.</p>

  <dd>SQL injection vulnerabilities enable malicious users to execute arbitrary SQL code on a database, allowing data to be accessed, modified, or deleted irrespective of the user's permissions. In almost every case you'll be accessing the database using Django’s querysets/models, so the resulting SQL will be properly escaped by the underlying database driver. If you do need to write raw queries or custom SQL then you'll need to explicitly think about preventing SQL injection.</dd>
