Oracle APEX is a powerful tool for building enterprise applications quickly, but its ease of use can sometimes lead developers to overlook user experience (UX) best practices. Many APEX apps are built without a dedicated UX designer, leaving developers to make critical design decisions. When time is tight and budgets are limited, it’s easy for UX to become an afterthought. The result? Apps that might function flawlessly from a technical perspective but leave users feeling frustrated and overwhelmed.
The goal isn’t to turn developers into designers. Instead, it’s to equip you with a few practical UX principles that can enhance usability—without requiring a deep dive into design theory. In this post, we’ll cover five foundational UX principles tailored specifically for APEX developers to help you build cleaner, more intuitive interfaces.
1. Organize Related Information to Simplify Navigation
When users encounter a screen cluttered with unrelated information, they struggle to find what they need. The more logical your layout, the easier it is for users to build a mental model of your application. This concept aligns with Miller’s Law, which suggests that users can only hold about 7 (plus or minus 2) pieces of information in their working memory at once.
How to Apply This in APEX:
- Group related fields into logical sections: Use region headers, cards, or accordions to separate content by category. For example, when designing a form to update employee information, split it into sections like personal details, contact info, and job information.
- Leverage tab layouts and stacked reports: Instead of creating separate pages for closely related data, use tabbed regions or stack multiple reports on a single page. For instance, you can present customer details, order history, and support tickets as tabs within a single view. This reduces context-switching and keeps users focused.
- Simplify dropdowns and lists: Long dropdowns can overwhelm users. Consider using search-enabled select lists or breaking choices into smaller, logical groups to make selection faster and more manageable.
Organizing information effectively helps users navigate APEX applications more confidently, reducing frustration and speeding up task completion.
2. Reduce Clicks with In-Context Actions and Flat Hierarchies
Excessive clicking not only frustrates users but also disrupts their workflow. Each additional click is a point of friction that can cause users to abandon tasks. Simplifying information architecture and keeping actions in context can significantly improve usability in APEX. The goal is to minimize friction by reducing the number of steps required to perform common actions, making your applications feel faster and more efficient. (Of course, not all friction is bad — sometimes it’s necessary before completing irreversible actions, such as deleting records or submitting financial transactions.)
How to Apply This in APEX:
- Flatten information architecture: Avoid creating deep hierarchies that force users to click through multiple layers to find key information. For example, if users frequently edit records, add edit icons directly to interactive reports instead of redirecting them to a separate page.
- Use in-context actions: APEX’s dynamic actions can streamline workflows, but simpler options like row-level edit icons or inline editing for grids can often provide a faster solution without the need for custom JavaScript.
- Combine steps intelligently: Multi-step processes should be a last resort. If necessary, use modal dialogs for secondary tasks to keep users on the main page. For example, you might use a modal for updating shipping details without leaving the order management screen.
By reducing friction thoughtfully—keeping actions readily accessible while maintaining safeguards for critical tasks—you help users move through workflows more efficiently without sacrificing control and accuracy.
3. Focus Each Page on a Single Primary Action
When users see too many options, they hesitate or choose none at all—a phenomenon explained by Hick’s Law, which states that decision-making time increases with the number of choices. A clear, singular focus on each page prevents analysis paralysis and guides users toward completing tasks efficiently.
How to Apply This in APEX:
- Emphasize one primary action per page: If a page is designed for entering customer information, the primary action should be to save that data. To make this action stand out, set only one button per page as Hot in APEX. The Hot button style is designed to draw attention and guide users to the main task without overwhelming them with choices.
- Use distinct call-to-action buttons: Ensure that primary buttons stand out using contrast in color and size. In APEX, this can be done through button templates and theme styles to create a consistent look and feel.
- De-emphasize secondary actions: Options like download CSV or print can be included but should be presented as text links or less prominent buttons to keep the focus clear.
By limiting each page to a single Hot button for the main action, you simplify decision-making and help users move forward with confidence.
4. Use Typographic Hierarchy and Contrast to Guide Users
Clear typographic hierarchy and contrast aren’t just about aesthetics—they’re essential for helping users scan and process information quickly. This principle is related to the Von Restorff Effect, which suggests that distinct elements stand out and are easier to find. Ensuring that text is both readable and accessible is a critical part of this approach.
How to Apply This in APEX:
- Establish a consistent typographic hierarchy: Use headings, subheadings, and body text systematically (as in this example from the Material Design standard). APEX Universal Theme makes this straightforward by providing pre-defined typography classes. Ensure that H1 is used for page titles, H2 for section titles, and so on.
- Leverage contrast for important information: Adjust font size, weight, and color to highlight critical warnings, next steps, or primary actions. For instance, use a bold and contrasting color for error messages to make them unmissable.
- Avoid setting user-facing text in all caps: Text in all caps is difficult to read and can cause issues with screen readers that struggle to interpret it properly. If you want text to appear in all caps, use the CSS style text-transform: uppercase instead of typing it directly in uppercase. This approach preserves accessibility while achieving the desired look.
- Avoid excessive variation: Too many font styles or colors can confuse users. Stick to a limited palette that aligns with your APEX theme for a clean and professional look.
Good typography helps users understand information at a glance, reducing cognitive load and ensuring that your APEX applications are accessible to all users.
5. Simplify Forms for Usability and Efficiency
Forms are at the heart of many APEX applications, and poorly designed forms can quickly frustrate users. Tesler’s Law emphasizes that complexity is unavoidable, but it should be handled by the system, not the user. Simplifying forms and minimizing the information users have to input manually can significantly enhance usability.
How to Apply This in APEX:
- Be thoughtful about defaults: Pre-fill fields with known information whenever possible. For instance, use APEX’s PL/SQL dynamic actions to populate default values based on user roles or prior selections.
- Avoid floating labels: While floating labels might seem sleek, they often cause confusion by appearing like placeholder text. Stick to standard labels above input fields for clarity.
- Use clear labels and helper text: Descriptive labels and concise helper text prevent users from second-guessing what information is required. Make sure to use APEX’s item help features for complex fields.
- Minimize required fields: Ask only for essential information to reduce friction. Optional fields can be moved to secondary tabs or collapsible sections to simplify the primary form.
- Leverage conditional logic: Show or hide fields based on user input to keep forms focused and prevent users from feeling overwhelmed. APEX’s dynamic actions make this relatively straightforward.
By streamlining forms, you reduce user frustration and speed up data entry, which is especially valuable for enterprise applications where users may interact with forms frequently.
UX Principles to Improve APEX Usability, Not Replace Designers
The UX principles covered in this post aren’t a replacement for having a dedicated UX designer on your team—nothing can substitute for the depth of expertise that a designer brings. However, by applying these practical guidelines directly within APEX, you can significantly improve the usability of your applications.
Streamlining information architecture, reducing decision points, and designing forms with efficiency in mind can make a noticeable difference in user satisfaction. While you may not have a UX designer on every project, these small adjustments can go a long way in making your apps more intuitive and user-friendly.
Start by applying one or two of these principles to your next APEX project and see how they improve the experience. And if you do get the opportunity to work with a UX designer, you’ll be better equipped to collaborate effectively and build applications that users love.
