SPRINGERBRIEFS IN COMPUTER SCIENCE REAL-TIME ...

While traditional databases excel at complex queries over historical data  they are inherently
pull-based and therefore ill-equipped to push new information to clients. Systems for data
stream management and processing  on the other hand  are natively push­oriented and thus
facilitate reactive behavior. However  they do not retain data indefinitely and are therefore
not able to answer historical queries. The book provides an overview over the different
(push-based) mechanisms for data retrieval in each system class and the semantic differences
between them. It also provides a comprehensive overview over the current state of the art in
real-time databases. It sfirst includes an in-depth system survey of today's real-time
databases: Firebase  Meteor  RethinkDB  Parse  Baqend  and others. Second  the high-level
classification scheme illustrated above provides a gentle introduction into the system space of
data management: Abstracting from the extreme system diversity in this field  it helps readers
build a mental model of the available options.
