Questions tagged [data-access]

Data access typically refers to software and activities related to storing, retrieving, or acting on data housed in a database or other repository.

Data Access is simply the authorization you have to access different data files. Data access can help distinguish the abilities of Administrators and users. E.g. Admins may be able to remove, edit and add data, while a general user may not be able as they don’t have the access to that particular file.
