Big Bang Integrations

We represent a company called as lt infotech. This organization is building a food delivery application
We have different teams who are working in isolation
Approach
- Each team will work in isolation for 8 months and finish development
- On the first day of 9th month we will start integrating and test the application
This approach is called as Big Bang integration
This almost fails all the time
Generally to fix issues most of the teams go for workarounds

We represent a company called as lt infotech. This organization is building a food delivery application
Approach:
- From day 1 all the teams need to integrate their work
- Accept failures and plan for proper fixes rather than technical debts
Integration was majorly done manually, so this needs to be replaced with automated tools
Integration approach:
- Whenever a new change is done in any part of the system
- build the code
- test the integration with automated tests
- publish the results
Developer will have the feedback of his changes
To work with continuous integration we need
- A tool which builds the code
- A tool which runs the tests
- A tool which which notifies the users via email or … about failures and success.
tools ():
- Cruise Control for CI
- Makefile for building the code

Version Control System is a software for maintaining Code. It is basically a source code repository
Generations:
- Single System Version Control
- Client Server Version Control
- Distributed Version Control
