Real-time databases and data services

The real-time database (RTDB) controlling systems which consists of computer and human interfaces and coordinate the activities on the factory floor was discussed. A traditional database provided some of the functionality required by these applications such as coordination of current actions and consistent access to shared data. RTDB was capable of maintaining time-constrained data and time-constrained transactions in comparison with the traditional database. RTDB was expected to maintain not only the logical consistency of the data and transactions but it must also satisfy transaction timing properties and data temporal consistency
