Shared Components Flashcards

Where in Oracle APEX are Shared Components primarily accessed?

Answer: Application Builder → Application Home

Shared Components are accessed from the Application Builder's application home page, where they appear as a dedicated section for reusable application-level objects.

What is the main purpose of a Static List of Values (LOV) in APEX Shared Components?

Answer: To provide a fixed set of display/return value pairs reusable across pages

A Static LOV defines a fixed set of display and return value pairs at design time, making them reusable across multiple page items without a database query.

Which type of LOV in Oracle APEX executes a SQL query against the database each time it is rendered?

Answer: Dynamic LOV

A Dynamic LOV runs a SQL SELECT statement at runtime to fetch display and return values from the database, allowing the list to reflect current data.

An Application Item in Oracle APEX is best described as:

Answer: A global session-state variable accessible across all pages of an application

Application Items are global session-state variables that hold values at the application level, making them accessible from any page within the application.

What is the purpose of an Application Process in Oracle APEX?

Answer: A PL/SQL block that runs at the application level on a specified processing point

Application Processes are PL/SQL blocks defined in Shared Components that execute at the application level (not page level) at designated processing points such as On New Instance or On Load.

Build Options in Oracle APEX allow developers to:

Answer: Control which components are included or excluded during development and testing

Build Options are flags that can be attached to application components to include or exclude them during specific development phases, making it easy to toggle features without deleting them.

Application Computations in Shared Components are used to:

Answer: Set Application Item values using SQL or PL/SQL when a specified event occurs

Application Computations calculate and assign values to Application Items at defined processing points using SQL queries, PL/SQL blocks, or static values.
