Key-value Coding in Java

I would like to introduce a guide to the key-value architecture of domain objects where their attributes are provided using objects called Keys only. The Key-value approach simplifies and accelerates the development of applications. Practical use is demonstrated in the Demo-Hotels project linked at the end of the original article. The chapter list follows:

• Writing and reading values
• Restoring default values
• Shallow copy of an object
• Validation attributes when writing
• Composite Keys
• Criterion as a condition model
• Criterion for filtering collection
• Collection sorting
• Serialization of Keys
• Import from CSV format

Short examples are based on the Ujorm library.
