Question

Describe the tradeoffs inherent in receiving surveillance data transmissions once per day (i.e., batch transmission) vs. real-time. Consider tradeoffs from the perspectives of alert timeliness, human/system resources required, and infrastructure.

Answer 1

Surveillance Data Transmission-Trade Off
Batch transmission or once per day transmission of surveillance data creates issues on alert timeliness. Since availability or collection of data is running in a batch basis, the ability of the surveillance to be alert under various situations reduces as it lacks real time functioning. That creates limitations even in the intentions of the surveillance to be accurate and alert. Also, that limits the ability to react accordingly to fraud, observed in the surveillance. Real time transmissions take the advantages of alert timeliness since the transmission is observed moreover live. Updating continuously with the movement of time reduce the chances of missing an alert given by the surveillance and make the process efficient and trouble free.
Batch transmission requires less human or system resources. Since the data is collected only once in a period, the efforts needed is less when compared to that of the real time transmissions. But, at the time of transmission the effort combines and become more than that of the real time transmission. The need of regular analysis and concern is less in the case of batch transmission and high in case of the real time one. Being updated continuously, the real time transmission demand better care and continuous efforts when compared to the batch transmission. The need of resources is high since the function is live always. Batch transmission demands only few resources since the transmission is done only once in a period.
Batch transmission requires less infrastructure since the transmission is required only once in a period. The channels for the data to be updated regularly demands better infrastructure in the case of real time transmissions. For free and efficient transfer of data demand advanced technology that does not interrupt the continuous flow of data through the channels. Since the working of real time transmission is continuous, the infrastructure used to be of better quality and high efficient. Channels can be through internet or other mediums which will again increases the need of better infrastructure for real time transmissions when compared to the batch type.

The feature of continuous performance of real time transmission costs better and demands higher infrastructure for efficient and effective transmission of data with less strain.
