Mixed Deck — All ORACLE APEX Topics Flashcards

In Oracle Application Express, what role does continuing education play in report building?

Answer: To keep professionals current with evolving standards, technologies, and best practices

Continuing education ensures professionals stay current with new developments, evolving standards, and emerging best practices in their field, maintaining competence throughout their careers.

What is a best practice in Oracle Application Express report building?

Answer: A method or technique recognized as superior based on evidence and expert consensus

Best practices are methods, techniques, or approaches that are recognized through evidence, research, and expert consensus as producing superior results and are recommended for adoption.

How can you prevent a specific column in an Oracle APEX Interactive Grid from being editable by end users?

Answer: Set the column's 'Is Editable' property to No in Page Designer

Setting the column's 'Is Editable' property to No in Page Designer makes that specific column read-only within the editable grid.

What is the function of the 'Current for Pages' attribute on an Oracle APEX navigation List Entry?

Answer: It specifies which page numbers should highlight this entry as the active/current menu item

The 'Current for Pages' attribute defines which page IDs cause the navigation entry to appear highlighted as the currently active menu item.

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.

Which processing point is enabled for computations during page processing?

Answer: Processing

Explanation: Computations during page processing are enabled at the "Processing" processing point. This point occurs after the page has been submitted but before any processing occurs, allowing computations to be performed before any other actions are taken.

Which two actions can be done by a Page Process of type Automatic Row Processing (DML)?

Answer: Apply a SQL WHERE clause to append to all generated INSERT, UPDATE, and DELETE statements at run time.

Explanation: Apply a SQL WHERE clause to append to all generated INSERT, UPDATE, and DELETE statements at run time. This statement isn't a capability of Automatic Row Processing (DML) specifically. Automatic Row Processing focuses on handling insert, update, and delete operations on individual rows efficiently without directly manipulating the generated SQL statements. Invoke PL/SQL code to perform the inserts, updates, and deletes. This option is correct. Automatic Row Processing (DML) can indeed invoke PL/SQL code to perform the inserts, updates, and deletes.

Which is true about a workspace in Oracle APEX?

Answer: It can be associated with multiple schemas in the same database.

Explanation: In Oracle APEX, a workspace can be associated with multiple schemas within the same database. This allows developers to work with data from different schemas within the same workspace, providing flexibility in application development and management.

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.

In Oracle Application Express, why is form development knowledge important for professional certification?

Answer: It demonstrates competence and ensures practitioners meet established standards

Professional certification in specific knowledge areas demonstrates that practitioners have met established competency standards, ensuring quality of service and public protection.

What Oracle APEX component type is used to display a navigation menu on a page using a side navigation or tree layout?

Answer: List Region

A List Region on a page displays a List shared component and can be styled as a navigation menu, side bar, or tree using list templates.

What is the difference between qualitative and quantitative research in Oracle Application Express?

Answer: Qualitative explores experiences and meanings; quantitative measures and counts numerical data

Qualitative research explores experiences, perceptions, and meanings through methods like interviews and observation. Quantitative research measures variables numerically through surveys, experiments, and statistical analysis.

The Globalization section under APEX Shared Components is used to:

Answer: Define application language, character encoding, date/number formats, and translation files

The Globalization section in Shared Components controls language settings, date/number format masks, character semantics, and the translation workflow for creating multilingual applications.

In Oracle Application Express, what does "chain of custody" refer to?

Answer: The documented, chronological record of evidence handling from collection to presentation

Chain of custody documents every person who handles evidence, when they received and transferred it, and what they did with it, ensuring evidence integrity and admissibility.

John has a form page with an email item and a status item. What must John do to ensure that the email item is populated before users can enter any value into the status item on the form page?

Answer: Validation on the email item

Explanation: By applying validation on the email item, John can ensure that the email field is populated before users can enter any value into the status item on the form page. This ensures that the required email field is filled out before proceeding to the next field, maintaining data integrity.

Where is the Oracle APEX session state stored between calls from the browser?

Answer: In the browser in the form of cookies

Explanation: Oracle APEX session state is typically stored in the browser in the form of cookies. These cookies maintain session information, allowing the application to maintain its state across multiple requests from the same user.

What Oracle APEX Interactive Grid attribute must be configured to enable row selection for use with JavaScript or Dynamic Actions?

Answer: Row Selector

The Row Selector attribute adds a selection checkbox column to the Interactive Grid, enabling row selection that can be read via JavaScript or Dynamic Actions.

The following are classes of vulnerability that affect APEX applications except:

Answer: Automated control

Explanation: Automated control is not a class of vulnerability that affects APEX applications. Vulnerabilities are weaknesses or flaws in a system that can be exploited by attackers, and automated control does not fall into this category. SQL injection, access control, and cross-site scripting are all common vulnerabilities that can affect APEX applications. SQL injection involves inserting malicious SQL code into a database query, access control refers to inadequate restrictions on user access and permissions, and cross-site scripting involves injecting malicious scripts into web pages viewed by other users.

In Oracle APEX, which Interactive Grid column type should be used to display a checkbox for boolean or Yes/No data?

Answer: Checkbox

The Checkbox column type in Interactive Grid renders a checkbox UI control suitable for boolean or Yes/No column values.

What is a best practice in Oracle Application Express sql workshop?

Answer: A method or technique recognized as superior based on evidence and expert consensus

Best practices are methods, techniques, or approaches that are recognized through evidence, research, and expert consensus as producing superior results and are recommended for adoption.
