Version Control

Avoiding Loss of WorkJane opens clsDataConnection in Visual StudioBob adds a new method to clsDataConnectionBob saves his work on the classJane completes her work modifying the code

for clsAddressBookIn the process Jane also saves

clsDataConnectionThis reverts clsDataConnection back to its

original version overwriting the new code created by Bob

Wider Implications for CustomersBob and Jane work on the system to produce version 1.0 of the

productVersion 1 is released to customersMore work is carried out and version 1.1 is released which is

chargeableSome customers report that with version 1.0 there is a bugCustomers refuse to upgrade to version 1.1 due to the cost and

want a fix for version 1.0 (This will create version 1.01)The question then arises how to manage the code not just to

handle multiple versions of the code in use by developers but also multiple versions of the code over the history of the system.

These problems are not trivial!
