Tasks for Self Learning 1

☝
In this chapter you will find individual tasks that you should solve independently with the help of the documentation. They have nothing to do with the actual agenda and are there to deepen your knowledge
  • Task 1
  • Combine two tables in one DSO
  • Task 2
  • Create a backend DSO
  • Task 3
  • Enable the Omni-Search for the customer

Task 1

Combine two tables in one DSO

Result: You have a grid which shows data from the Customer and the Order table

Task: Create an own entity - Create an DSO based on that entity - Create grid based on that

Documentation:

Combine multiple Tables in one DSO

In this documentation you will learn how to combine several tables into one DSO. For example, you want to display the contents of two tables in a grid or form. To do this, create a new entity with a source query that combines these tables. From the table you can generate the DSO and all other objects.

Task 2

Create a backend DSO

Result: You have a grid based on a backend DSO

Task: Create the backend code for your class - Create the entity and DSO for your backend class - Create a grid for it

Documentation:

Create an Entity and DSO without a DB/Table

In B1, it is possible to create data sources and entities based on a Backend Data Source Object (DSO). This implies that there is no need for a physical database with a table in the background. To achieve this, create a Backend DSO and a temporary table. Based on these, an entity is generated. Subsequently, a Data Source Object (DSO) can be created based on the generated entity.

Task 3

Enable the Omni-Search for the customer

Result: The user is able to search for a specific customer

Task: Enable the Omni Search based on the documentation

Documentation:

Global search (OmniSearch)

The global search is one searching window for all possible entities. So a developer can configure the searchable entities and for each entity another target window could be opened.
