If you're just getting started with Oracle APEX (Application Express), you're in the right place. Oracle APEX is a low-code development platform that lets you build scalable, secure enterprise apps quickly, using only a web browser and SQL/PLSQL knowledge. It’s free with Oracle Database, making it a powerful tool for beginners and professionals alike.

Here’s a beginner-friendly guide to help you get up and running with Oracle APEX.

1. What is Oracle APEX?

Oracle APEX is a web-based software development environment built on top of Oracle Database. You can create interactive web applications — from simple data entry forms to complex reporting dashboards — without needing deep front-end or back-end coding skills.

Key features:

• Drag-and-drop interface builder
• Built-in security and scalability
• Responsive design (mobile-friendly apps)
• Integrated with Oracle Database
• Free to use with Oracle Database

APEX is ideal if you:

• Know basic SQL
• Want to build apps fast
• Don’t want to deal with complex web frameworks

2. How to Set Up Oracle APEX

Before you start building, you need access to an APEX environment. Here are your options:

Option 1: Use Oracle APEX on apex.oracle.com (Recommended for Beginners)

This is the easiest way to get started — no installation needed.

Steps:

• Go to //m.sbmmt.com/link/f925407353b2aaefee1a0c3b31be5fc1
• Click Try It Free or Sign Up
• Create a workspace (you’ll get a URL like https://yourname-apex.apex.oracle.com)
• Log in to your workspace

✅ Pros: Free, no setup, instant access
❌ Cons: Limited resources, not for production

Option 2: Install APEX in Your Own Oracle Database

For more control (e.g., local development or enterprise use).

Steps:

1. Install Oracle Database (Express Edition is free)
2. Install and configure APEX
3. Set up Oracle REST Data Services (ORDS)
4. Access APEX via http://localhost:8080/ords

? This route is more complex and better suited once you’re past the beginner stage.

3. Your First APEX App: Step-by-Step

Let’s create a simple employee tracker app.

Step 1: Create a New Application

• Log in to your APEX workspace
• Click Create App
• Choose New Application

Step 2: Add a Page

• Click Create Page
• Select Interactive Grid from Table or View
• Choose Create Table (we’ll make one)

Step 3: Create a Table

APEX can generate a table for you.

Example table: EMPLOYEES

• Columns: ID (Number, Primary Key), NAME (Varchar2), EMAIL, DEPARTMENT, SALARY
• Let APEX generate forms and constraints

Click Create Table and Data Load.

Step 4: Build a Form and Report

• APEX automatically creates:
  • A form to add/edit employees
  • An interactive grid (report) to view all employees
• These are added as pages in your app

Step 5: Run Your App

• Click Run Application
• Test adding a few employees
• Play with the report (sorting, filtering, etc.)

You now have a working app — in under 10 minutes!

4. Understanding the APEX Interface

When building apps, you’ll work in the APEX Builder. Key areas:

• Navigator – Shows pages, regions, processes
• Page Designer – Visual layout tool (drag-and-drop)
• Properties Panel – Configure components (buttons, items, validations)
• Preview – See how the page looks

Spend time exploring:

• Adding buttons
• Creating validations (e.g., “Salary must be > 0”)
• Changing themes and templates

5. Key Concepts for Beginners

Here are a few terms you’ll see often:

• Workspace: Your private area in APEX (like a project folder)
• Application: A collection of pages (your app)
• Page: A single screen (e.g., login, report, form)
• Region: A section on a page (e.g., a chart, form, or grid)
• Item: Input fields (text box, date picker, etc.)
• Process: Logic that runs (e.g., saving data)
• Validation: Rules to check user input

Tip: Start with pre-built templates — they save time and teach you best practices.

6. Tips to Level Up

Once you’re comfortable:

• Learn SQL and PL/SQL — they’re essential for logic and data handling
• Explore dynamic actions — make pages respond to user input
• Use shared components — for navigation, security, and lists
• Try charts and dashboards — turn data into visuals
• Publish your app to a custom URL (if self-hosted)

Final Thoughts

Oracle APEX is beginner-friendly because it removes the complexity of full-stack development. You focus on data and user needs, not infrastructure.

Start small: build a to-do list, contact manager, or inventory tracker. Then gradually add features like authentication, reports, and emails.

The best way to learn? Just build.

基本上就这些 — no magic, just consistent practice.
