Dimensions and measures are the keys, defining the critical centricity of data points. These form crucial parts of every business intelligence software and data analytics software. Let’s first understand the basic definition of ‘Dimensions’. They are categorical data points or attributes around which the numbers or factual numbers revolve to build different analysis story points. Let’s consider we have 5 different data points in a fictitious data set: Region, State, Product, Sales and Quantity. Now given these fields, the Region, State and Product fields are what make the dimensions for this data set. We could further categorize, aggregate, slice and dice to answer business questions. They are like the powerhouse for any data set. A wiser term to use could be they are qualitative in nature, and help:
Measures are quantitative in nature. Using the above fields, we can easily say that Sales and Quantity define the measure of our fictitious data set. On the measure, we quantify the data from above and ascertain what sales are (aggregated value right) and what quantity is sold in a particular region. Here, the quantity being a measure and region, being a dimension, are combined to answer business-specific questions. Measures are what add validity to the dimension-related data points.

Now that we know what dimensions and measures are, a more purposeful discussion area is the combination of both. Together, dimensions and measures are what make an analysis of purpose. Both form an essential part of business intelligence software. Measures can be calculated, or new ratios and further questions could be answered based on the data granularity. To put in simple terms, measures are the numbers that define the key characteristics for a given dimension which we could further slice and dice to reach a business-specific ask being made. More concepts revolve around dimensions and measures like dimensionality, continuous and discrete, aggregations, relationships etc. Our core object here is just to familiarize you with these terms.
Recall any of the cricket matches. Now to decide which side gets to bat or ball we used to toss, right? The deciding factor in eliminating the bias. We all have seen a coin (in case you have one right now, just flip it). Like there are two sides to a story, much like a coin (pun intended); let’s relate to it with our dimension and measure here. To build a more understanding point, I would say the ‘Head’ side of the coin is a dimension right above which state, currency, logo etc., more of a qualitative data point. The ‘Tail’ side of the coin, which has a number on it, is what a measure is, as that is what adds significant numeric value, quantitative data.
