IBM calls these characteristics volume, variety, velocity and veracity. Big Data Big Data Apache Hadoop Ecosystem for Big Data Types of Data Discrete – derived from counting something. For example, a delivery is either on time or not; an order is complete or incomplete; or an invoice can have one, two, three, or any number of errors. Some discrete metrics would be the proportion of on-time deliveries; the number of incomplete orders each day, and the number of errors per invoice. Continuous – based on a continuous scale of measurement Any metrics involving dollars, length, time, volume, or weight, for example, are continuous.
