Services | Business Entity-Relationship Modeling

GET STARTED!

Central to my Metis approach to application technical design is the assertion that business information systems are essentially composed of three basic kinds of things: business entitiesprocesses, and rules.

  • Entities represent the nouns — the persons, places, and things that these systems are intended to manage.
  • Processes are the verbs — the actions that operate on and orchestrate the interactions of these entities.
  • Rules (or “decisions”) are the logic and conditions that inform and constrain these processes.

 

Entity-Relationship DiagramEach business entity model consists of name, attribute, data type, relationship (cardinality, ordinality), and dependency data and metadata (e.g. minimum and maximum values, validation criteria, etc), as well as any entity-specific scripted lookup/reference data.

These models can be used to create corresponding data structures, e.g. database tables, microservices, application programming interface (API) documents, and user interface components, and can be grouped in the business domains to which they belong.

Let’s identify and model your organization’s key business entities positioning you for better data collection and analytics, automated processes, and business rule definition!
