Version Control Is Necessary Of Application Source Code In High Availability Database Servers

Version of the source code seems fairly common in large organizations

. Therefore, this trick is targeting small and medium enterprises, where the source code is not under version control. Developers of many small businesses, I work to think of versions of source code as an unnecessary overhead. Incongruously, many of these small businesses, Internet start-up companies that are require high availability to remain financially viable. The importance of version control of source code in the 24 * 7 availability and run-time environment cannot be overstated.

Imagine a situation this way: You just released a critical application. Six promoters were involved in writing code. Each developer has written a dozen programs. Each developer has the source code in the files directory. After a few weeks, end users demand improved and a couple of programs should be modified to suit new needs. The developer who worked in the family is sick and is absent from work. In contrast, another developer has a copy of the source code, make changes and put into production after proof thereof. Again, after a couple of weeks, end users demand more than a few additions to the programs. But now the original developers who worked on these programs is to return to work. He just got today, meet the new requirements, quickly pulled the source code of legal age in your local directory, make any changes it deems appropriate, to submit to testing, and push them to production.

Version of the application seems to be always in motion and changes in September to explain the problem to another developer. But if the source code is old so there's no trick to use to see what the latest version. Using the list, we are able to follow all these defects and changes in each application. Unfortunately, in most cases, this document, a list or index is not maintained. If possible, so that you do not update properly Fri One reason may be changes, the developer changes the job, a long holiday, a temporary developer outsourcing transition, etc.

Source code version control to prevent these scenarios, where multiple copies and versions of the program to float, causing confusion and potentially significant downtime, because valuable time is spent identifying and correcting errors. Million in the previous scenarios came to mind. Being short, the story is this - to make sure that all the production version of the source control and that all versions are funneled through the correct order, without a second ignore the others. Version control allows you to maintain a back-out plan before the new code. If the new code has serious bugs, back-out plan will allow you to downgrade and return to a previous version of a program or application.

Working quickly, of course, was too fast. Well, in the scenario just described, the changes made by the promoter of another absent from the original developers have been lost.
