You've already decided the "data structure" by deciding on a database! It is table, column, and row based, so your structure is going to be reasonably flat.

Me? I'd have a table for users, and a separate table for posts, which includes a foreign key to the users table. And the Posts table would just have a timestamp column which lets your queries retrieve user-based posts for any time period(s) you might desire.

By your method, I need to get the all database for 4 queries per day, weekly, monthly and yearly, which is not optimal.

Assuming you just want the number of posts, you can use GROUPING SETS to get the summary by year, month, and day in a single query.

Summarizing Data Using the GROUPING SETS Operator - Simple Talk[^]

SELECT
    YEAR(PostDate) AS PostYear,
    MONTH(PostDate) AS PostMonth,
    DAY(PostDate) As PostDay,
    COUNT(1) As NumberOfPosts
FROM
    UserPosts
WHERE
    UserID = @UserID
GROUP BY
    GROUPING SETS
    (
        YEAR(PostDate),
        (YEAR(PostDate), MONTH(PostDate)),
        (YEAR(PostDate), MONTH(PostDate), DAY(PostDate))
    )
;
