Every year we collect more data than before, and the tools we use to manage that data are evolving to accommodate our changing needs - but it can be difficult to keep up with all the innovations! This session will give you a tour of what's happening in open source databases, from someone who lives the adventures of open source data in her day job. You will travel from the well-trodden paths of relational databases, through the leafy glades of time series, to the landmarks of search and document databases. This session is recommended for people with an interest in software who want to learn about the overall trends, license changes, rising stars, and which database technologies are here to stay.
