In the world of databases and data analysis, the ability to reorganize and summarize data efficiently is a critical skill. One powerful technique to achieve this in SQL is known as pivoting. SQL Pivot enables the transformation of data from rows into columns, allowing for a more intuitive and comparative view of information. This is especially useful when dealing with large datasets that require aggregation or cross-tabulation. Unlike traditional SQL queries that return data in a row-wise manner, pivoting restructures data to present it in a matrix-like format. This approach…

A process in Linux is an instance of a running program. When you execute a command or launch an application, the operating system creates a process to run that program. This process includes the program code, current activity, resources it uses such as memory and open files, and its position in the system’s process hierarchy. Each process is uniquely identified by a Process ID (PID). Additionally, processes have attributes like parent process ID (PPID), priority, memory usage, CPU time consumed, and open files. Linux manages these processes independently but allows…
