Embedded Databases: Data Management for Real-Time and Embedded Systems

The term embedded database was coined in the 1980s to mean a database management system (DBMS) that is embedded into an application, in contrast to large central databases (nowadays, usually client/server DMBSs a la Oracle). The first embedded databases had little or nothing to do with embedded systems, which were largely 8-bit, or possibly 16-bit, devices that performed a very specific function. Any data processing requirements were promoted to a higher layer in the system architecture. Embedded systems, like all other facets of computing, have matured and gained faster (32-bit) processors, memory, and more complexity. This has further confused conversations about embedded systems and embedded databases. Today, the term embedded database encompasses databases embedded into software applications, as well as the more modern client/server database design (although embedded client/several varieties are much smaller than their enterprise-level DBMS cousins such as Oracle or DB2). In fact, while embedded databases comprise a sizeable chunk of the overall database market, they show remarkable diversity in important respects such as programming interfaces, storage modes, and system architecture. This article examines some of these differences to help in choosing the right embedded database system for a given project.

MILS: An Architecture for Security, Safety, and Real Time

The unrelenting growth and integration of embedded controls, information processing, and communications has created a need for systems that provide robust protection for resources and services in the face of serious threats. Formerly diverse requirements for different kinds of systems are now being merged into combined requirements to be met by a single system. To address this trend, a partnership of government, industry, and research institutions are developing the MILS (Multiple Independent Levels of Security/ Safety) architecture. Although being pursued initially for defense applications, MILS provides a foundation for critical systems of all kinds. Its security, safety, and real-time properties make it suitable for such diverse applications as financial, medical, and critical infrastructures. Based on a new breed of commercially available high-assurance products, MILS provides a modular, flexible, component- based approach to high-assurance systems.
