implement the same algorithm to calculate pi using mpi4py similar to. The worker process finds the area under the function 1+x2 for its associated part as before. The number of processes is broadcast to all workers which can find their portions and then do the calculations using the function calc_pi. The root process then collects all results from the workers by adding them using the reduce operation and prints the result. Note that we can specify what to do with the collected data in reduce operation.

Intermediate SQL Concepts

A query is a request for data or information from one or more database tables. This information could be presented in the form of pictorials, graphs, or complicated findings which helps in easy interpretation. Structured Query Language (SQL) is the most widely used programming language for retrieving and organizing data from relational databases. Collection of tables with rows and columns is referred to as a database. SQL is the language of databases. It makes it easier to extract specific data from databases, which can then be used for analysis.
