BUILDING BLOCK - Business Software System

Description	Abstract Concept A Business Software System is a Business System used by Business Operations, that represents all granularities of software - ranging from MicroServices to enterprise wide Application Systems - used by Business Operations. All Business Software Systems share the following characteristics: 1) They provide Functionalitys. 2) They expose APIs (Application Interfaces) through which they deliver Information Outcome Events. 3) They handle datastores defined by Physical Data Domains. 4) They perform and participate to System Processes. Systemic Levels of Business Software System: a Business Software System is either a Software Module or an Application System
