Wipro Expecting More Projects on Analytics and Cloud
#Wipro Expecting More Projects on Analytics and Cloud:
Bangalore-based IT firm WiproBSE 1.17 % expects to land bigger deals for solutions based on digital technologies like social, mobility, analytics and cloud, a sign that companies are willing to increase their spend on these discretionary areas. 

"While our sweet spot is deals in the $2.5-3.5 million (Rs 15-21 crore) range, we are seeing deals worth $5-10 million (about Rs 30-60 crore) in the pipeline," Jeff Heenan-Jalil, global head of Wipro's advanced technology solutions unit said  in an interview to ET. 

Wipro's rivals including TCS, InfosysBSE 1.65 % and Accenture have all created separate units to target the digital business, which is based on the technologies which go by the acronym SMAC. The business has typically involved smaller deals till now and posed a problem for IT companies trying to raise their share of revenue from these services.

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...

 Here are five popular SQL queries frequently used in data analysis. 1. SELECT with Aggregations Summarize data by calculating aggregates like counts, sums, averages, etc. SELECT department, COUNT(*) as employee_count, AVG(salary) as average_salary FROM employees GROUP BY department; 2. JOIN Operations  Combine data from multiple tables based on a related column. SELECT e.employee_id, e.name, d.department_name FROM employees e JOIN departments d ON e.department_id = d.department_id; 3. WHERE Clause for Filtering Filter records based on specified conditions. SELECT * FROM sales WHERE sale_date BETWEEN '2024-01-01' AND '2024-12-31'   AND amount > 1000; 4. ORDER BY Clause for Sorting Sort results in ascending or descending order based on one or more columns. SELECT product_name, price FROM products ORDER BY price DESC; 5. GROUP BY with HAVING Clause Group records and apply conditions to the aggregated results. SELECT department, SUM(salary) as total_salaries FROM employ...
