Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. If a primary server fails, a backup server can take over and continue to serve requests.

MongoDB is a non-relational document database that provides support for JSON-like storage. Alternatively, we can choose a version that is too early and not yet tested enough for production use. Indexing can help to speed up read queries, but it comes with an extra cost of storage, and they will slow down write operations.

The goal is to produce a low-energy hardware classifier for embedded applications doing local processing of sensor data. Race logic has four primary operations that are easy to implement in hardware: MAX, MIN, ADD-CONSTANT, and INHIBIT. One efficient way of doing that in analog hardware is the use of current-starved inverters.
