Major components of an Electronic Document Management System include imaging, document management, and approval workflow processing. Digitized documents are stored off-site. Some of these systems will store images of documents, whereas some software solutions include optical character recognition, which can translate scans of documents into editable text. This software is also used as a database of sorts, allowing for searching and sorting of the mass of documents collected. Electronic document management software is a very efficient means of storing information, and can greatly reduce the amount of labor that is required to do simple tasks. It safeguards against the loss of paper documents and ensures that a historical document can easily be edited without having to make copies. It also allows for very easy transmission of documents. Security is another benefit, given that computer systems are far easier to secure than files to which many people have physical access.
