Domain-driven design (DDD) is a major software design approach, [1] focusing on modeling software to match a domain according to input from that domain's experts. [2] DDD is against the idea of having a single unified model; instead it divides a large system into bounded contexts, each of which have their own model.
Data mesh is a sociotechnical approach to building a decentralized data architecture by leveraging a domain-oriented, self-serve design (in a software development perspective), and borrows Eric Evans’ theory of domain-driven design [1] and Manuel Pais’ and Matthew Skelton’s theory of team topologies.

In other words, during application development, the domain is the "sphere of knowledge and activity around which the application logic revolves." —Andrew Powell-Morse [2] Domain: A sphere of knowledge, influence, or activity. The subject area to which the user applies a program is the domain of the software. —Eric Evans [3]
In computer programming, the specification pattern is a particular software design pattern, whereby business rules can be recombined by chaining the business rules together using boolean logic. The pattern is frequently used in the context of domain-driven design.
Sample domain model for a health insurance plan. In software engineering, a domain model is a conceptual model of the domain that incorporates both behavior and data. [1] [2] In ontology engineering, a domain model is a formal representation of a knowledge domain with concepts, roles, datatypes, individuals, and rules, typically grounded in a description logic.
Eric J. Evans (fl. 1966–2011), British academic and historian Eric Evans (priest, born 1902) (1902–1977), Archdeacon of Warrington Eric Evans (technologist) , a technologist who coined the term domain-driven design in 2003
The data design is usually coded up as conventional classes that represent the basic domain structure of the system. These classes are barely smart data, [1] [2] and they explicitly lack the functionality that is peculiar to support of any particular use case. These classes commonly encapsulate the physical storage of the data.
The business process is "stormed out" as a series of domain events which are denoted as orange stickies. It was invented by Alberto Brandolini in the context of domain-driven design (DDD). Event storming can be used as a means for business process modeling and requirements engineering.
