I am going to start E -commerce website soon. I am new to manage live website. this website has lots of product details, product Images,source code in PHP and script files. After it will live there would be many updations, corrections and patching in code will be done. As it's an startup so i don't have any other resource to manage it. It will be manage by me only.
Here My question is what will be best method to manage source code updation and maintain logs for this to efficient traceable. should it will maintain line by line updation logs.
