There is a wide spectrum of solutions for structuring and managing your data, with Content Management Systems (CMS) at one end and custom databases at the other.
Regardless of what digital tool or solution you are building—a website, a smartphone application, an application for a wearable device, or anything else—data is what makes an application useful and valuable. I use the word data in a very broad way. In some cases the word content is used. Either term refers to the information (including files) that your application is either gathering, publishing, or processing.
Do you ever think, "How on Earth did I get here?" I do. A lot. Sometimes it's while pondering how my curiosities in life led me to this moment in time, like now—sharing this really cool thing with you that we created, called Elebase. But most of the time I find myself asking that question because I wandered off from where I was initially going. I get lost. I get curious. I explore.
