🛠️ How to Create an ER Model & Generate DDL for Oracle APEX | Lucidchart Database Design

In this *how-to video**, I walk you through the **entire process of designing a database* using *Entity-Relationship (ER) modeling* in *Lucidchart* and converting it into a *relational schema* with *primary and foreign key connections**. Once the schema is finalized, we generate **DDL (Data Definition Language) statements* to create tables in *Oracle APEX* and go over **common code generation errors**—and how to avoid them. By the end of this video, you’ll have a *clear understanding of database design**, how to **map an ER model to a relational schema**, and how to **efficiently generate and troubleshoot DDL statements* for **Oracle APEX**. --- 🛠️ *What We Cover in This Video:* ✅ *Creating an ER Model in Lucidchart* 📊 ✅ *Converting the ER Model into a Relational Schema* 🔄 ✅ *Defining Primary & Foreign Keys for Data Integrity* 🔑 ✅ *Generating DDL (CREATE TABLE statements) for Oracle APEX* 📝 ✅ *Troubleshooting Common Errors in DDL Generation* ⚠️ --- 🔍 *Common DDL Errors & How to Avoid Them:* 🚨 *Incorrect Data Types* – Choosing the right column types for your database 🚨 *Missing Primary or Foreign Keys* – Ensuring relational integrity 🚨 *Naming Conventions* – Avoiding reserved keywords and ensuring readability --- 🎥 *Demo: ER Model to Oracle APEX Tables* We *design a sample ER model**, convert it to a **relational schema**, and walk through **every step* of the *DDL generation process**. You’ll learn how to **validate and refine your database design* before deploying it in **Oracle APEX**. --- 📖 *Related Videos & Resources:* 📌 *Lucidchart ER Modeling Tutorial* 👉 [Watch Here](   / yourlinkhere  ) 📌 *Database Normalization Explained* 👉 [Watch Here](   / yourlinkhere  ) 📌 *Oracle APEX SQL Workshop Basics* 👉 [Watch Here](   / yourlinkhere  ) --- 📌 *Who Should Watch This Video?* 🔹 *Database Designers & Developers* creating relational models in *Oracle APEX* 🔹 *Software Engineers & Students* learning *database design best practices* 🔹 *Data Analysts & Architects* working with *SQL & ER modeling* 🔹 *Anyone interested in learning how to properly design databases* for real-world applications --- 🔔 *Subscribe for More Database & OOP Content!* If you’re interested in **ER modeling, database design, and SQL development**, don’t forget to: 👍 *Like this video* if you found it useful 💬 *Comment below* with any questions or topics you’d like to see 📢 *Share this video* with fellow developers & database designers ✅ *Subscribe* for more *OOP & database tutorials* --- *📌 Keywords & Tags for SEO Optimization:* #ERModel #Lucidchart #DatabaseDesign #SQL #OracleAPEX #DDL #DatabaseSchema #RelationalDatabase #DataModeling #PrimaryKey #ForeignKey #EntityRelationshipModel #SQLTutorial #OracleSQL #SoftwareEngineering #DatabaseNormalization
