How can I learn big codebase?

Let’s take a look at a few ways in which you can start to grasp a monolithic codebase.

How long does it take a developer to get up to speed?

Depends on the code base, documentation, developer skills and knowledge and some other factors but I would say that a typical time frame is between three and six months. Generally speaking you expect people to be at full speed in six months in any normal project. In highly advanced projects the time can be much longer.

How long does it take an engineer to get up to speed?

In most of the companies we surveyed, engineers and managers reported it takes 3 to 9 months to be fully ramped-up. There is also a significant percentage of companies where it takes a full year.

What is the best way to approach programming?

Approaching it in way that you find the skeleton of the system first and then start filling in the details. Writing down call trees that show how to get from one place to the other in the code. Many times this is just one particular area not the whole system. Use of tools that help you understand the code.

What is the best way to learn a huge code base?

Working with the code is the best way to learn it. There is no “express” way to learn a huge code base, but there are a few things you can do. You can try modifying the code to add small features and to refactor and learn the code base in that way. Try focusing on small, localized sections of the code base,…

How can I tell if a codebase is tightly coupled?

There are tools that analyse codebase and tell you whether it’s tightly coupled and how much duplicate code is there. This might be useful, but not at the start of your project. Check whether there are any unit tests. Start running those to see what the system is capable of doing.

What is the best way to learn Java?

Students have developed it over couple of years and the bad part: The students who wrote this have already graduated. The existing documentation (only in the form of Javadocs, not UML stuff) is a lot but not helpful in terms of understanding the application design. Working with the code is the best way to learn it.
