QEWD-JSdb: It's a Database, Jim, but not as we know it! - Rob Tweed at LNUG, Jan 2020
With QEWD-JSdb, the database is no longer something that exists on another server, no longer effectively a separate technology that you access via a network connection using its in-built APIs, and which imposes on you a database model over which you have no control. Let's face it: most mainstream databases are "one trick ponies" that model data in one particular way: fine if all your database requirements fit that model, but most likely you'll have circumstances that mean you either end up consuming valuable time fighting that model to fit your needs. or end up having to support multiple databases with all the resulting additional pain, aggravation and maintenance overhead.
But you're not limited to persistent JSON: it's easy to model pretty much any type of database, both NoSQL and Relational/SQL on top of the basic persistent JSON data structures. In fact, QEWD-JSdb comes with some already created for you to use and/or explore, including:
Redis-like Key/Value (actually Key/Object) store
Document/JSON database storage
XML DOM database storage via the DOM API, with XPath querying
Relational with SQL read/write access
Once you're familiar with the basics of QEWD-JSdb, you can create your own custom database model if the built-in models don't meet your needs: no more time wasted fighting the database!
It's even possible to simultaneously apply different database models to the same physical QEWD-JSdb data!
All sounds too good to be true? Come and find out at Rob's talk on QEWD-JSdb.
