Data Analysis Using SQL
What I learned
Practical SQL exercises in filtering records, joining tables, grouping results and producing summaries. The focus was using query results to answer a clear analytical question and test an interpretation of the data.
Practical work
August 2024. Practical querying exercises compared subsets of data and refined analytical questions based on the results.
Start with a question
I practiced starting with a clear question, inspecting the returned records and adjusting the query to understand what the results meant.
SQL data analysis
Filters narrow the records, joins connect related tables, and grouping with aggregation produces useful comparisons and summaries.
