Oracle Application Express, also known as APEX or perhaps APEX, we're flexible like that, is a low-code development platform that enables you to build scalable, secure enterprise apps with world-class features that can be deployed anywhere. Using APEX, developers can quickly develop and deploy compelling apps that solve real problems and provide immediate value. You don't need to be an expert in a vast array of technologies to deliver sophisticated solutions. Focused on solving a problem and that APEX take care of the rest. Oracle APEX is a fully supported, no cost feature of Oracle Database. If you have Oracle Database, you already have Oracle APEX. You can access APEX from database actions. Oracle APEX, on autonomous database, provides a pre-configured, fully managed, and secure environment to both develop and deploy world-class applications. Oracle takes care of configuration, tuning, backups, patching, encryption, scaling and more, leaving you free to focus on solving your business problems. APEX enables your organization to be more agile and develop solutions faster for less cost and with greater consistency. You can adapt to changing requirements with ease and you can empower professional developers, citizen developers, and everyone else. You will be prompted to login as the administrator at first, then you may create workspaces for your respective users and login with those associated credentials. Application Express provides you with an easy to use browser-based environment to load data, manage database objects, develop rest interfaces, and build applications which look and run great on both desktop and mobile devices. You can use APEX to develop a wide variety of solutions, import spreadsheets, and develop a single source of truth in minutes, create compelling data visualizations against your existing data, deploy productivity apps to elegantly solve a business need or build your next mission critical data management application. There are no limits on the number of developers or end users for your applications. APEX embraces SQL. Anything you can express with SQL can be easily employed in an APEX application. Application Express also enables low code development, providing developers with powerful data management and data visualization components that deliver modern responsive and user experiences out of the box. Instead of writing code by hand, you are able to use intelligent wizards to guide you through the rapid creation of applications and components. In this example, using the quick SQL utility, we're able to paste table titles and their properties into the left pane. APEX will automatically create the SQL script to create those respective tables on the right. Creating a new application from APEX App Builder is as easy as 1, 2, 3. One, in App Builder, select a project name and a parent's. Two, add pages and features to the app. Three, finalize settings and click "Create". Application Express is built into autonomous database. It is a low-code development platform that enables you to build scalable, secure enterprise apps with world-class features that can be deployed anywhere.
