Abstract

En 中文

Self-adaptive Software (SaS) is a special category of software systems that enables adaptation at runtime to address new user requirements or changes in its execution environment. This article focuses on a specific category of SaS named SaS2DB, which encompasses systems that require the storage of data in a database. In short, a SaS2DB must understand the changing needs and implement a strategy to execute the evolution of its data schema. The evolution of data schema is a complex issue that encompasses data schema migration, data migration, and other non-functional requirements.
