LEVEL 1: Concept

• Basic programming concepts: Scratch introduces fundamental programming concepts such as sequences, loops, conditionals, and events. Users learn how to arrange blocks of code to create scripts that control the behavior of sprites (characters or objects) in their projects.
• Animation and storytelling: Scratch allows users to create interactive stories and animations by adding sprites, creating backdrops, and animating characters using different movements and effects. Users learn how to create dialogue, create scenes, and sequence events to tell a story.
• Game design: Scratch provides tools for creating simple games, including creating sprites with different behaviors, designing game mechanics, implementing game logic, and creating user interfaces. Users learn how to create games with different levels of complexity and interactivity.
• Multimedia and sound: Scratch supports adding multimedia elements such as images, sounds, and music to projects. Users learn how to upload and use media assets in their projects, as well as how to program interactions with multimedia elements, such as playing sounds or displaying images at specific times.
• Interactive art and music: Scratch allows users to create interactive art and music projects by combining programming with creative elements. Users can create visual effects, animations, and interactive music compositions using Scratch's visual programming blocks.
• Collaboration and sharing: Scratch encourages collaboration and sharing among users through its online community. Users learn how to share their projects, remix and modify existing projects, and collaborate with others by providing feedback and suggestions on projects created by fellow Scratch users.
• Computational thinking: Scratch promotes computational thinking skills, such as problem-solving, logical reasoning, and algorithmic thinking. Users learn how to break down problems into smaller steps, plan and debug their projects, and think critically to create interactive projects.

LEVEL 4: Backend Development

Backend developers typically use programming languages such as PHP or NODEJS as well as frameworks and libraries to build and maintain the backend infrastructure of web applications. They work closely with front-end developers, database administrators, and other team members to ensure the smooth operation of web applications. Some specific tasks that a backend developer may be responsible for include designing and implementing APIs, building and maintaining databases, and deploying and scaling web applications.

MongoDB is a NoSQL database that stores data in a document-oriented format, which means data is stored as JSON-like documents. MongoDB is highly scalable and flexible and is commonly used for handling large volumes of unstructured or semi-structured data. It is commonly used in applications that require real-time processing and analytics such as social media platforms and financial trading systems. MongoDB uses a flexible data model and a query language called MongoDB Query Language (MQL) which allows developers to work with data in a more natural and intuitive way. MySQL, on the other hand, is a relational database management system (RDBMS) that stores data in tables with predefined schemas. MySQL is highly popular, widely used, and has been around for a long time. It is commonly used in applications that require a well-defined structure for storing and querying data, such as e-commerce websites, financial applications, and content management systems. MySQL supports SQL (Structured Query Language) which is a powerful language for managing and querying relational data. Both MongoDB and MySQL have their own strengths and weaknesses, and the choice of database system depends on the specific needs of the application being developed.
