Business Intelligence Architecture — Explained for an 11-year-old

Imagine a school that wants to make the best lunch menu, sports schedules, and class plans. Business intelligence (BI) is like the school using facts and numbers to make smart choices. Here is how the whole system works, step by step.

1. 1) Strategy: The plan or goal

   Strategy is the school's plan. It answers questions like: What do we want to improve? More students eating lunch? Better test scores? In BI, adults decide what goals they have before they look at any data.

2. 2) Data sources: Where information comes from

   Data sources are like places the school gets information. Examples:

   • Registers that say how many students came to lunch (attendance)
   • Surveys where students say which meals they like (opinions)
   • Cash registers that show what food was bought (sales)
   • Sports scores and test results

   Think of data sources as ingredients in a kitchen.

3. 3) Collecting & cleaning the data (ETL)

   Before using the data, you need to gather it and tidy it up. ETL means:

   • Extract: take the data from different places
   • Transform: fix mistakes, make formats the same (like turning dates into the same style)
   • Load: put the cleaned data into a big storage

   It is like washing and chopping ingredients before cooking.

4. 4) Data warehouse and data marts: Where data is stored

   A data warehouse is a giant storage room that holds all the cleaned information from many sources. It keeps everything in one safe place so people can look up facts quickly.

   A data mart is a smaller shelf inside that storage room made for one team. For example, the lunch team might have a data mart with only food and sales info. Data marts make it faster to find things for a specific purpose.

5. 5) Data analysis: Looking at the data to learn things

   Data analysis is like reading recipes and tasting food. People make charts, tables, and reports to answer questions such as:

   • Which lunch sold the most last month?
   • Are fewer students coming in on Mondays?
   • Which class has the highest test scores?

   These answers help the school decide what to do next.

6. 6) Data mining: Finding hidden patterns

   Data mining is like being a detective. It uses computers to look for hidden patterns that people might miss. For example:

   • Maybe hot lunch sales go up when the weather is colder.
   • Or students who come late to class also skip lunch more often.

   Data mining helps discover new ideas that can lead to better plans.

7. 7) Decisions and actions

   Finally, the school uses what it learned to make decisions. For example, they might change the menu, give coupons on cold days, or change lunchtime minutes. Then they watch the data again to see if the plan worked. This completes the BI cycle and matches the strategy from step 1.

Quick example: The cafeteria

• Strategy: Get more students to eat school lunch.
• Data sources: Cash register sales, student surveys, weather reports.
• Collect & clean: Combine everything and fix wrong dates or missing answers.
• Store: Put the data in the data warehouse; the lunch team uses a data mart.
• Analyze: Make charts showing which meals sell best and when.
• Mine: Find that hot soup sells more on rainy days.
• Decide: Offer a soup special on rainy days and check later to see if more students buy lunch.

People and tools

People who work with BI include data analysts, data engineers, and managers. Tools are dashboards, charts, and special software that helps collect, store, and analyze data.

Remember

Business intelligence is a step-by-step process: decide what you want (strategy), gather facts (data sources), clean and store them (ETL and data warehouses), look at them (analysis), dig for hidden ideas (data mining), and then make smart choices.
