Real-time Database Systems: An Overview of System Characteristics and Issuestion their mis-concepts. Part II discussed one of the most important issues in the design of RTDBS: concurrency control. Other issues related to the management of the systems are included in Part III. Part IV addresses real-time active issues, such as triggered transactions. Part V reports the resea

It is interesting to note that the numerical values for the application data characteristics shown for each domain are gen- erally stated neither in the “official” application requirements documentation, nor in the design documentation that reflects derive

Tei-Wei Kuo,Kam-Yiu Lam first in this process, retroviral RNA-directed DNA polymerase (reverse transcriptase), catalyzes the synthesis of a DNA copy of an RNA template in the presence of a suitable primer. Reverse transcriptase (RT) was discovered in 1970 (.,.) and was first used to copy a eukaryotic cell mRNA in 1971 (.–
