Operational Architecture typically deals with the technical and process details of how systems operate day-to-day, not a long-term summary view.

Segment Architecture provides a detailed, often domain-specific, architectural view for a particular segment or area of the enterprise, not a summary of the whole.

Strategic Architecture offers an executive-level, long-term perspective of the entire enterprise, providing a high-level vision and roadmap. It focuses on the overarching business goals and how architecture supports them across the organization.

Tactical Architecture addresses short-to-medium term architectural decisions and solutions, not a long-term, summary view of the entire enterprise.
