Martin Strohbach, Jörg Daubert, Herman Ravkin, and Mario Lischka.

This chapter provides an overview of big data storage technologies.

Traditional storage systems can fall short for both real-time big data applications that need very low latency and data mining applications that can amass huge data warehouses.

Big data storage architecture considerations include storage type, data protection and data analytics. And like so many technologies , the industry seems absolutely hell-bent on creating exclusive stovepipe object storage methodologies . Rather than elaborating on concrete individual technologies, this chapter provides a .

Intermediate lighting wiring diagram

Two-way and intermediate lighting circuit. The wiring diagram above is what you need to memorise in order to wire the circuit on the day of the AMexam. It might look intimidating at first glance, but actually it is quite simple.


Three core and earth cable is required to install two or three way switching and this should be run from the first light switch to second switch ( intermediate ) and then to the third switch and then wired as shown in this diagram. Switch one is the switch that contains the live wire .

An intermediate lighting circuit is used when one circuit is to be turned on or off by three or more switches.

The single circuit may have one or more lights in it.

This type of circuit uses two of the two way switches and one or more of the intermediate switches. A wiring and circuit diagram is shown . It should be fitted between the first and the last switches on the circuit. If replacing an existing switch, note the location of the terminals and the colour and position of cable connections.
