Technology Guidelines


Under Construction...

MVC vs. Zscript

When to use MVC

MVC (Model-View-Control) is a design pattern that separates the model, view and controller clearly. It is easy to collaborate, develop and maintain. In addition, the performance is great. MVC is strongly suggested for development, especially for production systems.

When to use zscript

Zscript allows you to embed Java code in ZUML pages. It speeds up the design cycle, so it is suggested for prototyping, POC and testing. It is also good for exploiting ZK features and reporting bugs to ZK. However, Like any interpreter, the performance is not good, and tends to be error prone, so it is not suggested to use in production systems.

MVC Extractor

ZK Studio provides a tool called MVC Extractor that can convert zscript to MVC automatically. It simplifies to transfer the code from prototyping to production.

Data Binding

When to use

Data Binding automates the data-copy plumbing code (CRUD) between UI components and the data source. It is strongly suggested whenever applicable, because it boosts the productivity a lot and the code is easy to read and maintain.

When not to use

Barely. However, it requires more knowledge to learn than EL expressions, so EL expressions is an alternative for people, such as UI designer, not familiar with ZK, especially in the UI design phase.

ZUML vs. Richlet vs JSP

When to use ZUML

ZUML is the most effective way to design and compose UI. It does not require programming knowledge, and works well with MVC, Data Binding and others. It is strongly suggested unless you have different preferences.
