Traditional word processing documents and portable document format (PDF) files are easily read by humans but typically are difficult for machines to interpret. Other formats such as extensible markup language ( XML ), ( JSON ), or spreadsheets with header columns that can be exported as comma separated values (CSV) are machine readable formats.
While many electronic document management systems store documents in their native file format (Microsoft Word or Excel, PDF), some web-based document management systems are beginning to store content in the form of HTML. These HTML-based document management systems can act as publishing systems or policy management systems. [1]

[1] [2] The following is a list of the most common types of database objects found in most relational databases (RDBMS):
A document retrieval system consists of a database of documents, a classification algorithm to build a full text index, and a user interface to access the database. A document retrieval system has two main tasks: Find relevant documents to user queries; Evaluate the matching results and sort them according to relevance, using algorithms such as ...
An open file format is a file format for storing digital data, defined by a published specification usually maintained by a standards organization, and which can be used and implemented by anyone. For example, an open format can be implemented by both proprietary and free and open source software , using the typical software licenses used by each.
