Indexing a SQL Server database in some respects is considered both an art and a science. Since this is the case, what are some considerations when designing indexes for a new database or an existing one in production? Are these the same types of steps or not?

When is it okay to let SQL Server to make a statistic for columns in your queries, and when should you take those statistics and make an index out of them? What I do is to test all of my procs, and if they generate system statistics (_WA_SYS%), then I add an index to the table for the column in the statistic. But is this a good practice?

I have some data in a table:
CREATE TABLE #test_data
(
id INT PRIMARY KEY,
name VARCHAR(100),
birth_date DATE
);
-- Step 2: Insert rows
INSERT INTO #test_data
VALUES

SELECT *
FROM OPENJSON(
(
SELECT t.* FROM #test_data AS t FOR JSON PATH
)
) t; See possible answers
