First of all, as a software developer whenever we use the term software domains mostly we will be talking about the “Business domain”.
The business domain is the area for which our software product or service provides some kind of solution.
If you are a software developer, please make sure to check my blog on
To understand Software domains better, let’s take some example:
- Advertisement etc.
Ok, so as you might be aware of the term domain it can be a group or cluster of some small units that may be called sub-domains which in itself is a domain.
Let’s take the example of Telecom here:
In the telecom domain, you might be working on one of these sub-Domains.
- Networking – This domain facilitates you with calling and messaging(SMS) services. It can be implemented using diameter protocol i.e 4G or Http protocol i.e 5G.
- Ordering Management System– OMS Deals with the devices, plans or subscriptions that an end-user buys from the telecom company.
- Billing– It handles all the monetary or Charging related info of a subscriber or customer.
- Customer Management System- CMS is used to store Customer info into the system like customer name, mobile number or Address.
So the moment you join software development you might be working in one of the sub-domain of a larger domain.
These sub-domains will be related to each other in one way or other and as a whole, they represent a larger domain or Business For example AT&T, Vodafone, etc.
In Conclusion, I would say domain knowledge is very important for any software engineer. By gaining more of domain knowledge an engineer can excel in his career.
Additionally, It also helps you to get promotions as a Product Owner, Technical Lead and Technical Architect irrespective of your starting position in your career as a developer or tester.
I hope this article will help you to have a basic understanding of the software domains.
In case you think, I have missed any domain please feel free to comment.
