Microflows and nanoflows are both used in Mendix for defining business logic, but they differ in their scope and complexity.

• Microflows are used for larger and more complex processes, while nanoflows are used for smaller and simpler processes.

• Microflows can have multiple activities and can be triggered by events, while nanoflows have a single activity and are typically called from microflows.

• Microflows can have input an...read more

• Setting security for Sub Microflows is important to ensure data integrity and prevent unauthorized access.

• Sub Microflows may contain sensitive data or perform critical operations, so securing them is crucial.

• Access control can be implemented by defining user roles and permissions for Sub Microflows.

• Authentication and authorization mechanisms should be enforced to restrict access to Sub Microflows.

• Examples of securit...read more

Before commit and After commit Microflows are used in Mendix to perform actions before and after committing changes to the database.

• Before commit Microflows are executed before the changes are committed to the database.

• They are used to perform validations, calculations, or any other actions that need to be done before saving the data.

• After commit Microflows are executed after the changes are committed to the database.

• Change object activity - modifies the attributes of an existing object

• Commit activity - saves changes made to objects in the database

• Retrieve activity - retrieves objects from the database based on specified criteria

• Loop activity - iterates over a ...read more

Mendix supports REST API implementation for building web services.

• Mendix provides a built-in REST module that allows you to create and consume RESTful APIs.

• To implement a REST API in Mendix, you can define a microflow or a nanoflow that handles the incoming requests and processes the data.

• You can use the 'Expose as REST service' option in the microflow or nanoflow properties to make it accessible as a REST API.

• Mendix a...read more

Data view and List view are different ways of presenting data. Data view focuses on individual records, while List view displays multiple records in a tabular format.

• Data view presents data in a detailed manner, showing all the fields and values of a single record.

• List view displays multiple records in a condensed format, usually in a table with selected fields.

• Data view is useful for examining and editing individual r...read more
