Our objective is to design and implement an experimental real-time database system suitable for study of real time transaction processing.
Custora's data was based on real-time transactions for over 100 US-based retailers.
In particular, we are interested in studying the impacts of different scheduling approaches for soft real-time transactions on the performance of non-real-time transactions.
Real-time transactions can be lost, and potentially not recovered, introducing major risk and liability.
That is, these devices should be automated to enable real-time transactions and control.
Previous research in real-time concurrency control mainly focuses on the schedulability guarantee of hard real-time transactions and the reduction of the miss rate of soft real-time transactions.
Although many new database applications have significant response time requirements, not much work has been done in the joint scheduling of traditional non-real-time transactions and soft real-time transactions.
Their performance objective usually aims at the minimization of the number of missed deadlines of soft real-time transactions or to guarantee the deadline satisfaction of hard real-time transactions.
Note that this is an asynchronous process, not immediate, although real-time transactions are also possible.
But more importantly, these ads are also far more interactive and can create real-time transactions.
