Learn how to develop a data model for an IT infrastructure management application.
- [Instructor] In this lesson will address the question…of tuning table definitions to optimize queries.…As an example use case, let's look at IT infrastructure.…IT infrastructure includes a variety of devices,…including physical servers, storage devices…like SSD and disk drives, load balancers,…routers and other hardware.…In addition, the increasing use of virtualized entities…like virtual servers and software defined networks,…means the number and types of entities…that operations personnel have to manage is increasing.…
To help our increasingly burdened operations colleagues…we're going to build a database…to store inventory information about infrastructure.…Specifically, we will track devices,…their physical location, and the installation date.…The installation date will help us keep track…of devices that we want to retire after 3 years.…The device table includes…a universally unique identifier or UUID.…We can use a function in Cassandra to create these.…Notice, the key uses the ID plus the installation date.…
