Connexys is an application for Salesforce CRM software, and hence, we offer several links to Salesforce documentation about Roles and Profiles on this page.
Record-level Security
Record-level security lets you give users access to some object records, but not others. As with most applications, data access begins with a user. The application needs to know who you are before it provides access. For Salesforce, there are different types of users and, sometimes, the level of access is different by type. Instead of reviewing every attribute of every license type, we will focus on those interesting attributes that significantly impact data access. Record ownership and full access are synonymous and interchangeable and provide the user with the highest level of access to a record.
