Big Data versus Small Data

How do you know whether you are dealing with Big Data or Small Data?

How do you know whether you are dealing with Big Data or Small Data? I’m constantly asked for my definition of “Big Data”. Well, here it is…for batch analytics.

Big-Small

Batch Analytics

Batch Analytics Small Data Big Data
Data Volume Gigabytes Terabytes – Petabytes
Data Sources 1-6 (structured – SQL, or unstructured – NoSQL) 6+ structured AND 6+ unstructured
Business Functions One line of business (e.g. sales) Several lines of business all the way up to a 360 degree view of the business
Business Questions Queries are complex requiring many concurrent data modifications, a rich breadth of operators, and many selectivity constraints. However, they are applied to a simpler data structure.Example: determine how much sales is made on a given line of parts, broken out by supplier, by geography, by year.

 

 

Queries are complex requiring many concurrent data modifications, a rich breadth of operators, and many selectivity constraints. Queries span across business function.Example: determine how much profit (sales – COGs – allocated operating expense) is made on a given line of parts, broken out by supplier, by geography, by year; and then determine which customers purchased the higher profit parts, by geography, by year; determine the profile (demographics) of those high-profit customers; find out what products purchased by those high-profit customers were NOT purchased by other similar customers in order to cross-sell / up-sell.

The precious oil is extracted from the seeds of prickly pear cactus plant. After taking out the seeds from the fruits, they are adequately dried and then cold pressed to obtain the oil. Indeed, the prickly seed oil is quite expensive. Well, that is understandable when you consider the fact that the seeds are really tiny and each seed contain only about 5% of oil in it at most, plus the seeds are usually handpicked from the fruits. This means it will take tons of these seeds to produce just one bottle of the oil for commercial purpose. But from its medical properties to its culinary importance, skin lightening, moisturizing, and protection abilities, down to its extraordinary hair care properties, prickly seed oil has got lots of excellent rewards for anyone who pays the price.
