Data Storage

Axon.ivy provides multiple possibilities to manage and store project specific data. This chapter provides an overview of all the possibilities with their advantages and disadvantages. Which one should be used depends from case to case.

Content Management

Stores static multi language content like labels, texts, titles, images. More information can be found in the chapter Content Management System.

Web Content Folder

Stores static web files (CSS, JavaScript, Images, JSF-Templates) used in HTML User Dialogs. More information can be found in the chapter HTML content in the Web Content Folder.

Filesystem

Data can be stores in files. Access and management has to be implemented in the project itself.

HTML User Dialog Resources

Stores static web files (CSS, JavaScript, Images, etc.) that are only used in the HTML User Dialog.

Database

Stores and access data in an external database systems. An own database server is necessary and the database schema must be managed outside of Axon.ivy. More information can be found in the chapter DB Step.

Persistency (Java Persistence API)

Stores and access data in an external database systems. An own database server is necessary. The database schema can be generated. JPA is a Java standard that is well documented and widely used. More information can be found in the chapter Persistence.

Web Service

Stores and access data in external systems by using web services. More information can be found in the chapter Web Service Call Activity.

Global Variables

Application Custom Properties

User Properties

Stores simple name/value pairs per user. Can be used to store user settings. More information can be found in the Public API IUser.
