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 or

Information Architect Key Responsibilities

Gartner defines "enterprise information architecture" as that part of the enterprise architecture process. It is a set of requirements , principles and models — the current state, future state, and guidance necessary to flexibly share and exchange information assets to achieve effective enterprise change.  Enterprise information Architect also called EIA. Information Architecture  The transition from information that is isolated within applications to a flexible, comprehensive enterprise information architecture will require changes in technology, process, organizational structure and orientation.  In particular, EA practitioners comfortable with technical architecture must now devote time to understanding this emerging discipline.  Gartner projects that, EA teams will be forced by the business to spend as much time on information architecture as they currently spend on technical architecture.  Changes will also impact a range of disciplines across the organization and will
