A Document Management System (DMS) is a computer-based system that is used to store, manage, and track electronic documents and images. A DMS can be used to store a wide variety of document types, including text documents, images, spreadsheets, and presentations. These systems can provide tools for organizing and categorizing documents, as well as for setting access permissions and tracking changes to documents. Some DMS systems may also include features such as version control, which can help to ensure that the most up-to-date version of a document is being used. DMS systems can help businesses to improve the efficiency of their document management processes, reduce the risk of errors, and improve collaboration among team members.

Some of the modules that may be included in a DMS system include:
