Oracle Database 12c Application Development

1. PL/SQL

PL/SQL (Procedural Language/Structured Query Language) is Oracle's extension of SQL. It adds procedural features to SQL, allowing for more complex logic, error handling, and looping. PL/SQL enables developers to write stored procedures, functions, and triggers, making database operations more efficient and secure.

Example: Consider PL/SQL as a scriptwriter for your database. Just as a scriptwriter writes detailed scripts for a movie, PL/SQL allows you to write detailed scripts for your database operations, adding logic and structure.

2. SQL Developer

SQL Developer is a free integrated development environment (IDE) for working with SQL and PL/SQL in Oracle databases. It provides a graphical interface for managing database objects, writing and debugging PL/SQL code, and running SQL queries.

Example: Think of SQL Developer as a workshop for your database. Just as a workshop provides tools and space to build and repair things, SQL Developer provides tools and an interface to build and manage your database.

3. JDBC (Java Database Connectivity)

JDBC is a Java API for connecting and executing queries on the database. It provides a standard interface for Java applications to interact with databases, making it easier to develop database-driven applications in Java.

Example: Consider JDBC as a bridge between your Java application and the database. Just as a bridge connects two sides of a river, JDBC connects your Java application to the database, allowing seamless communication.

4. Oracle Call Interface (OCI)

OCI is a low-level, high-performance interface for accessing Oracle databases. It provides a set of C language functions that allow developers to build custom applications that interact directly with the Oracle database.

Example: Think of OCI as a direct phone line to the database. Just as a direct phone line provides a fast and reliable connection, OCI provides a fast and reliable interface for direct database interaction.

5. Oracle XML DB

Oracle XML DB is a feature of Oracle Database that provides native support for XML data. It allows you to store, index, query, and transform XML data directly within the database, making it easier to manage and process XML data.

Example: Consider Oracle XML DB as a specialized library for storing and managing books in XML format. Just as a library organizes and stores books, Oracle XML DB organizes and stores XML data.

6. Oracle Application Express (APEX)

Oracle Application Express (APEX) is a low-code development platform that allows you to build scalable, secure web and mobile applications using only a web browser. It provides a rich set of features for building database-driven applications quickly and easily.

Example: Think of APEX as a construction kit for building web and mobile applications. Just as a construction kit provides pre-built components to build structures, APEX provides pre-built components to build applications.

7. Oracle Data Integrator (ODI)

Oracle Data Integrator (ODI) is a comprehensive data integration platform that covers all data integration requirements, including batch loads, integration processes, and SOA-enabled data services. It provides a graphical interface for designing and managing data integration processes.

Example: Consider ODI as a logistics company for data. Just as a logistics company moves goods from one place to another, ODI moves data from one system to another, ensuring efficient and accurate data transfer.

8. Oracle GoldenGate

Oracle GoldenGate is a real-time data integration and replication software platform. It provides high-performance, real-time data integration and replication capabilities, making it ideal for mission-critical applications.

Example: Think of Oracle GoldenGate as a courier service for data. Just as a courier service delivers packages quickly and reliably, Oracle GoldenGate delivers data in real-time, ensuring timely and accurate data transfer.

9. Oracle SQL Developer Data Modeler

Oracle SQL Developer Data Modeler is a graphical tool that helps you design and manage database schemas. It provides a user-friendly interface for creating and modifying database models, making it easier to design and document database structures.

Example: Consider SQL Developer Data Modeler as an architect's blueprint tool. Just as an architect uses blueprints to design buildings, SQL Developer Data Modeler helps you design database schemas.

10. Oracle REST Data Services (ORDS)

Oracle REST Data Services (ORDS) is a middleware that simplifies the deployment of RESTful web services for Oracle Database. It provides a RESTful interface to the database, making it easier to build and deploy RESTful applications.

Example: Think of ORDS as a translator between the database and RESTful applications. Just as a translator helps two people communicate, ORDS helps RESTful applications communicate with the database.

11. Oracle SQL Developer Web

Oracle SQL Developer Web is a web-based version of SQL Developer that allows you to manage database objects, write and debug PL/SQL code, and run SQL queries directly from your web browser.

Example: Consider SQL Developer Web as a remote control for your database. Just as a remote control allows you to manage devices from a distance, SQL Developer Web allows you to manage your database from anywhere with an internet connection.

12. Oracle Database API for MongoDB

Oracle Database API for MongoDB allows applications that use MongoDB to interact with Oracle Database without changing the application code. It provides a MongoDB-compatible interface to the Oracle Database, making it easier to migrate MongoDB applications to Oracle.

Example: Think of the Oracle Database API for MongoDB as a compatibility layer. Just as a compatibility layer allows older software to run on newer systems, this API allows MongoDB applications to run on Oracle Database.
