As a software developer whenever we use the term domain mostly we will be talking about the “Business domain”.
Business domain is the area for which our software product/service provides some kind of solution.
To make you understand it better lets take some example:
- Telecom
- Finance
- E-commerce
- Healthcare
- Insurance
- Entertainment
- Gaming
- Travel
- Advertisement etc.
Ok, so as you might be aware of the term domain it can be said a group or cluster some some small units may be called sub-domains which in itself is a domain.
Lets take example of Telecom here:
In telecom domain you might be working on one of these sub-Domains.
- Networking - which will facilitate you with calling like 4G or 5G etc.
- Ordering Management - Deals with the devices/plans subscriptions bought by users.
- Facturation - Traite toutes les informations monétaires liées à un abonné, etc.
Donc, au moment où vous rejoignez le développement de logiciels, vous pourriez travailler dans l'un des sous-domaines d'un grand domaine.
Ces sous-domaines seront liés les uns aux autres d'une manière ou d'une autre et, dans leur ensemble, ils représentent un domaine ou une entreprise plus vaste comme AT&T, Vodafone etc.
