Using IndexedDB on Web Browser with Well Known Design Patterns — Only with Java by Mrs. Gwitany and Dr. Jackl

In the article “Using IndexedDB in Web Browser — All in Java” Mrs. Gwitany and Dr. Jackl told us how we could use Java with Elemental2 to build a simple prototype based on WebAPIs for IndexedDB. This time they’ll show us how to build the already shown code to be testable and maintainable with all the Design Patterns we already know from our server-side experiences with Java.
