ZK is primarily an UI framework and it doesn't make any assumptions about application's persistence layer or database.

Introduction
ZK is primarily an UI framework and it doesn't make any assumptions about application's persistence layer or database. Application developers are free to use any database (relational or non-relational) and any data access layer solutions that work with those databases. Typically, for relational databases developers either use plain JDBC or some sophisticated object-relational mapping library like Hibernate. In this small talk series I will show how developers can develop non-relational database driven ZK application.
I will describe a simple TODO list application that uses mongoDB which is a popular non-relational database. In this series I will show three approaches to work with mongoDB. In Part 1 I will use mongoDB Java driver APIs for TODO tasks CRUD operations which is similar to using JDBC driver for relational databases. In Part 2, I will use morphia , a lightweight type-safe library for mapping Java objects to/from mongoDB, which is similar to using Hibernate for relational databases. Finally for developers who are familiar with Spring framework, in Part 3 I will show how to leverage Spring Data mongoDB support to work with mongoDB database.
mongoDB Overview
mongoDB is a document oriented database that manages collections of BSON documents. Each BSON document is a set of fields. Each field is a key-value pair where key is a string and value can be other basic types, a BSON document or array of values. Below is a sample of tasks collection
{ "_id" : ObjectId("4e97d8b7dfa2925b0844a3c9"), "id" : "c011a1df-22ab-4607-a358-ea2f2873b51e", "name" : "Write article", "priority" : 1, "date" : ISODate("2011-10-06T16:00:00Z") }
{ "_id" : ObjectId("4e97d8e5dfa2925b0844a3ca"), "id" : "ce4a059f-1825-4410-bf95-4c30e11aca14", "name" : "Conference call", "priority" : 2, "date" : ISODate("2011-10-13T16:00:00Z") }
{ "_id" : ObjectId("4e97d8f0dfa2925b0844a3cb"), "id" : "0b0db7ac-b5db-40a6-9c8e-2c86581a3e89", "name" : "Release 5", "priority" : 1, "date" : ISODate("2011-10-27T16:00:00Z")}
