Towards Service-Based Database Management Systems

Today’s database management systems are mainly large and heavy-weight monoliths that, even worse, undergo steady extensions in functionality. This makes them highly complex and creates problems when it comes to build tailored extensions. Our goal is to introduce more flexibility and extensibility by founding our database architecture on the principles of Service Oriented Architecture (SOA). In this paper, we present a Service-Based Data Management System (SBDMS) architecture that supports extensions according to user requirements. The architecture we propose consists of four major service layers (Storage Services, Access Services, Data Services, Extension Services). Each of these layers can flexibly be extended with new services that invoke other services from within or outside the system. In addition, the architecture’s extension mechanism allows application functionality to be easily integrated into the Service-Based Data Management System to support reuse and optimization of commonly used application functionality.
