Forward delta schemes slow down over time as it takes longer and longer to generate the last submitted version so it can be compared to the current version you want to submit. Of course, that comes with a performance penalty as you might imagine.

Since most daily source code submissions are identical except for the few lines you added, deleted or modified, storing only the differences saves a lot of diskspace. The forward or reverse delta methods were devised when diskspace was at a premium.
Reverse delta means that your latest version is stored in its entirety and only the differences are stored for previous versions. Forward delta means that the initial version of a file is stored and for subsequent versions only the differences are stored. Some systems employ a forward delta scheme, others use reverse delta or store your files complete within their proprietary file format.
SQL Server in the case of Microsoft's Team Foundation Server (TFS). So the question is more like " How can you not need version control?"ĭepending on your system of choice, your code is stored in binary files of some proprietary format or in some type of database, e.g. Try explaining to your boss that the new features you have been bragging about in meetings all summer are all lost, because you clicked on a link in that one email from your friend. Today you have a few more threats that can ruin your day, ranging from malware, ransomware, laptop theft or simply forgetting to pick up your notebook or tablet after airport security. 1962, SCCS 1975) hardware failure and human error were the main factors that could corrupt or lose source code.

If you ever worked on a new version of software for weeks and then heard a clunk and a hard drive spinningĭown, you know what a horrible feeling that is. images, icons, data files, along with your source code.Īdditional features to look for are release management, which allows you to specify milestones and mark specific file versions for a project, and autonomous submits, which ensure files are submitted even if you forget. Most modern version control systems also support binary files, which allow you to
Depending on the system used, added comments on submit serve as a reminder for yourself and other team members what changes were made at the time. Additionally, it also keeps a record of who changed what in a team environment. It commonly allows you to restore previous versions of any submitted file, in case a change broke functionality or a file became corrupted. Version Control, also referred to as Source Code Control Management (SCCM), generally stores subsequent versions of source code files so you can access a history of changes. All of these questions will apply to any system you will ultimately choose to use. Don't let this discourage you from reading to the end. Of course I will use our own Version Control System, VersionRecall, to illustrate some of the topics. So, let's examine what questions and decisions will influence your choices.
A version control system is not something that really occupies the minds of IT management, so frequently the individual admin is left to his or her own devices. I exaggerate of course, but from some of the comments I hear, it is not that far off.
