Final answer:
The data flow architecture style is a software architecture that focuses on how data flows through a system. It covers application checking and validation, finance requirements, and decision notification, but does not typically cover social media integration.
Step-by-step explanation:
The data flow architecture style is a type of software architecture that focuses on how data flows through a system. It involves identifying processes, data stores, and data flows. In the context of a university admission processing system, the data flow architecture style would cover various domains.
1. Application checking and validation per university-wide and department-wide requirements: This is an essential component of the system as it involves checking and validating the applications to ensure they meet the necessary criteria.
2. Finance requirements: This domain would cover financial aspects such as processing application fees, scholarships, and other financial transactions associated with the admission process.
3. **Social media integration**: Social media integration is not typically a domain covered by the data flow architecture style. It falls more into the realm of system integration and user interface design.
4. Decision notification: This domain involves notifying applicants of their admission decisions and managing the communication process.
Based on the given options, the domain that is NOT covered by the data flow architecture style is social media integration.
