Having learned about relational databases along the way, I thought now was the time to tackle another technology. With these you can make more powerful, robust, secure, and faster CRUD applications than I was able to in Excel. While this course used SQLite 3, it attempted to impart a solid understanding of standard SQL. We covered the basics of creating and interacting with databases, in terms of creating and dropping tables/rows, updating values, making backups, creating views and using CRUD functions.
