Assertive Communication 

BE PROACTIVE - Be Proactive is about taking responsibility for your life. You can't keep blaming everything on your parents or grandparents. Proactive people recognize that they are "response-able." They don't blame genetics, circumstances, conditions, or conditioning for their behaviour. They know they choose their behaviour. Reactive people, on the other hand, are often affected by their physical environment. They find external sources to blame for their behaviour.

Time management

PUT FIRST THINGS FIRST -What are "first things?" First things are those things you, personally, find of most worth. If you put first things first, you are organizing and managing time and events according to the personal priorities you established.

Positive thinking


THINK WIN WIN -Win-win sees life as a cooperative arena, not a competitive one. Win-win is a frame of mind and heart that constantly seeks mutual benefit in all human interactions. Win-win means agreements or solutions are mutually beneficial and satisfying.

SQL Query: 3 Methods for Calculating Cumulative SUM

-
Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...
