There are some document management software that are accessible online. But, before proceeding to purchase one, it is helpful to have a better understanding of the idea of version control or revision control.

Version control is a feature that allows computer users to keep track of their files over time. This is important so that a user may get back to his previous working version in case he messes up. More technically, revision control is the management of revisions done on the same information unit. This is frequently utilized by engineering and software development companies to keep track of the ongoing development of their digital documents. Document changes are identified through a “revision number” or “revision level” which is an increment in the associated number or letter code of a document. what is more, the name of the individual who is responsible for a revision is also shown in the revision control code. For example, a digital document is assigned a revision code number “1.” When changes are done to this document, its revision code number is incremented to “2″. Revision control features are integrated into various software types like spreadsheets, word processors such as MSWord and Koffice and various content management systems. With this feature, a computer user is able to revert or go back to a previous revision or page for the purpose to correct any mistake committed.

Revision control is a crucial implement especially for computer software engineers and software developers. It allows the former to keep track and control changes made on source codes. Developers of software applications also utilize it to maintain documentation, source codes and configuration files. The majority of developers create multiple copies of different program versions while working on updates and software issues like bugs. These bugs are present only in several versions so when locating them, all versions of the software would need to be run. The practice of retaining multiple copies of programs is often done in large software companies. However, this practice is heavily criticized for its inefficiency.

A centralized model is as a rule used by software developers wherein all revision control functions are made on a shared server. In this set-up, two developers who perform changes on the same file at the same time may end up overwriting the work of the other. For the purpose to elude this occurrence, file locking is implemented. Files are locked to allow only one user to access it in any given time.

When choosing which among various document management software to purchase, make sure to choose one that can provide the necessary version control benefits. This document management software is beneficial even for people who are not developing software applications as it may be used to keep backup files especially concerning ongoing projects.
