This talk was first given at Code Mash 2019. It covers some of the aspects of how data management changes in the microservices world but also how data management has changed over time and where we have reinvented the wheel with failed attempts to change how we store and organize data.
Parts of this presentation is about to remind us that certain ways of doing things we had before and we are about to repeat the same mistakes.
Parts of this presentation is about common sense applied when dealing with data. The data tier cannot just be ignored or neglected when building new systems, data is the only thing that will still be there long when the applications or system on top has evolved. It's therefore crucial to make smart choices, based on actual requirements and business asks how to store and manage our data, rather than basing the decision on hyped technologies ranking high on Hackernews the last week.
Parts of the presentation is about capabilities that we already have since a long time in databases and that you might not know about. These are pointed out as potentially complimentary to your application architectures. It is again up to you to apply _your_ business requirements and common sense whether these capabilities solve your problem or not.
Note that this presentation is intended as visual aid for a talk. Parts of this presentation may be meaningless or wrongly intended without having the context that was given by me.
