EOS Introduces Demux For App Development
Demux is beneficial because it may allow blockchain events to be automatically updated and verified to a Mongo or Postgres SQL database. This type of process makes it easier to function within a database.

According to EOS, the prior interface was limited. The issue with the limiting quality is that it required multiple simple queries, rather than a single complicated one. This ultimately causes scaling issues, if scaling is relevant. Essentially, this new feature will allow for easier and more efficient development of EOS application.
