:Explain the differences between SQLite, Shared Preferences, and Room Database in Android. Provide a scenario where each storage option is the most appropriate.
In Android development, data storage is a critical component for building functional and responsive applications. Android provides multiple mechanisms to store data, each designed for specific use cases and levels of complexity. Three of the most commonly used storage options are SQLite, Shared Preferences, and Room Database. Understanding the differences between them, along with appropriate use cases, is essential for efficient application design. SQLite is a lightweight relational database management system embedded within Android. It allows developers to create structured databases using SQL syntax, supporting complex queries, relationships, and transactions. SQLite databases are file-based, meaning the data is stored persistently on the device's internal storage. This makes it suitable for applications that require structured data storage, such as storing user information, offline content, or large datasets. SQLite allows fine-grained control over the database schema, indexing, and querying, enabling developers to optimize performance for complex operations. For example, an e-commerce app that needs to store a catalog of products, each with multiple attributes ____ ___ ________ ____ ___ __________ ___ _____ _________ __________ _________ ____.
