Once upon a time .. access to a computer system was through an intermediary. The intermediary was an actual person – known as a machine operator or a key operator. This person worked 9-to-5, took off time for lunch, and input data into the System of Record, which was all about atomic transactions, and which, overtime, was all about relational transaction processing.
Then the Web happened, and nearly the entire population of the world became key operators. The input would come in great numbers, with unforecast spikes at unforeseen times. Web site operators began to collect data on the consumer army of key operators, to improve their Web experience. System of Engagement is a term that has come to describe that phenomenon.
Today, the System of Engagement has taken a place that is front and center in application development. For data management, that has meant wider use of non-relational NoSQL databases in operations. The systems handle vast amounts of data quickly, and thrive where relational alternatives now stumble.
The relational database still stands as the record of transactions. It is the final step – an important, but smaller, part of an overall system.
The impact of NoSQL and Systems of Engagement is the topic of this edition of the Talking Data podcast. We look at recent product updates in the space, and are joined by DataStax CEO Billy Bosworth for a free-wheeling look at the NoSQL terrain. Listen or download here.
