IndexedDB vs SQLite: What are the differences?
SQLite and IndexedDB are two popular databases used in web development. Let's explore the key difference between them.
-
Storage Mechanism: SQLite is a serverless and file-based database that stores data in a single file on the file system. On the other hand, IndexedDB is an in-built database provided by web browsers that stores data in a structured manner within the browser itself.
-
Data Formats: SQLite mainly supports structured data in the form of tables, much like traditional relational databases. IndexedDB, on the other hand, stores data as key-value pairs in a NoSQL format, allowing for flexible and schema-less data storage.
-
Query Language: SQLite uses SQL (Structured Query Language) for querying and manipulating data. It provides a wide range of SQL statements for data retrieval and modification. In contrast, IndexedDB uses JavaScript API methods for data retrieval and manipulation. It requires writing custom code using these methods to perform database operations.
-
Indexed Searching: SQLite provides built-in support for creating indexes on tables, which enhances query performance for filtering and searching data. IndexedDB, as the name suggests, also supports indexing, but it requires explicitly defining and maintaining indexes for efficient data retrieval.
-
Browser Compatibility: SQLite can be used in various programming languages and frameworks beyond web development, such as desktop and mobile applications. IndexedDB, on the other hand, is specific to web browsers and is not available for use outside of the browser environment.
-
Transaction Management: SQLite uses ACID (Atomicity, Consistency, Isolation, Durability) properties for data integrity and supports transactions. It allows multiple concurrent connections to the database. On the other hand, IndexedDB also supports transactions but follows a different transaction model based on event-based callbacks.
In summary, SQLite is a serverless, file-based database that stores structured data in tables using SQL, while IndexedDB is an in-built database provided by web browsers that stores data as key-value pairs in a NoSQL format, using JavaScript API methods for data manipulation. SQLite supports indexing, has wide programming language compatibility, and uses a transaction-based model, whereas IndexedDB is specific to web browsers, requires explicitly defining indexes, and uses an event-based callback transaction model.
