Most applications need to use input/output operations for files and databases. Explore how Ruby accesses and manipulates files on a disk and accesses information from databases. In this course, you will see how to define and use regular expressions to manipulate strings. Use the built-in File class to open, access, and close files. See how to write code that reads and writes data to a file, and manipulates files and directories on a drive. Learn how to run the MySQL2 Ruby Gem database connector, create a client connection, and execute CRUD operations, as well as select statements and prepared statements.
