Entire Data Engineering Process Simplified Explanation.
Data analytics is not scary, not scary at all.
We tend to overcomplicate some subjects. But when a new terminology appears, it appears in the same way as you learned in school, math, physics, chemistry, etc. It appears because it is needed.
Data analytics is required to make a decision and a strategy. For example, the question is: what price should I put for my product? You manually go through the markets, search for similar products and set your price. You did the work of a data analyst, and it is a data-driven decision. The same thing in business, and it is Business Intelligence.
New Problem: For data analytics using the same DB (MySQL, PostgreSQL...) for analytics can cause live production db to slow down, and even corrupt, interfere important transactions. Why? Because of read operations for analytics require looking up for millions of rows.
Solution: Copy live db to new one and use newly created for analytics.
