DevOps is defined as "unifying the operations and engineering teams," in order to foster a culture of cross-team collaboration, codify how infrastructure is built, and become a more data-driven organization. But it seems databases and the teams that care for them are treated as an exception to this environment. In most companies, databases are still treated like walled gardens, with the database hosts tended to like delicate flowers and the database administrators (DBAs) guarding any and all access to them. read more

One of my first exposures to computers in a work environment was using a Wyse terminal to access a console-based application for data entry. It wasn't until a while later that I learned about terminals in UNIX and how they work.

It's fairly simple to set up a database for basic CRUD (create, record, update, delete) applications, which is a common pattern, and it is useful in many projects.
