What is the advantage of Using SQLite rather than File?

In Android, entering data in SQLite uses more time and more lines of codes than in .txt file.

Saving data in .txt and use FileReader is convenient to get the data.

Is SQLite faster than file?

Once, yes, SQLite was faster—compared to operations involving a flat file.

What is SQLite and explain its features and advantages?

SQLite is self-contained means it requires minimal support from the operating system or external library. This makes SQLite usable in any environment especially in embedded devices like iPhones, Android phones, game consoles, handheld media players, etc. SQLite is developed using ANSI-C.

What is advantages of SQLite in Android?

Reading and writing from an SQLite database is often faster than reading and writing individual files from disk. See 35% Faster Than The Filesystem and Internal Versus External BLOBs. The application only has to load the data it needs, rather than reading the entire file and holding a complete parse in memory.

For what purpose we are using SQLite in our app?

SQLite Database is an open-source database provided in Android which is used to store data inside the user's device in the form of a Text file. We can perform so many operations on this data such as adding new data, updating, reading, and deleting this data.

Advantages of SQLite Databases over File Storage

  • If you have related pieces of data, regular files don't let you indicate their relationship; SQLite databases do.
  • SQLite lets you store data in structured manner.
  • SQLite has higher performance.
  • SQLite databases can also be queried and the data retrieval is much more robust.
  • The android.database and android.database.sqlite packages offer a higher-performance alternative where source compatibility is not an issue.
  • Android-databases created in Android are visible only to the application that created them
  • There is no file parsing and generating code to write and debug.
  • Content can be accessed and updated using powerful SQL queries, greatly reducing the complexity of the application code.
  • Extending the file format for new capabilities in later releases is a simple as adding new tables or new columns to existing tables.
  • Diverse content which might otherwise be stored as a "pile-of-files" can be encapsulated into a single disk file.
  • The content can be viewed using third-party tools.
  • The application file is portable across all operating systems, 32-bit and 64-bit and big- and little-endian architectures.
  • The application only has to load as much data as it needs, rather than reading the entire application file and holding a complete parse in memory. Startup time and memory consumption are reduced.
  • Small edits only overwrite the parts of the file that change, not the entire file, thus improving performance and reducing wear on SSD drives.
  • Content is updated continuously and atomically so that there is no work lost in the event of a power failure or crash.
  • Applications can leverage the full-text search and RTREE capabilities that are built into SQLite.
  • Performance problems can often be resolved using CREATE INDEX rather than redesigning, rewriting, and retesting application code.
  • A federation of programs, perhaps written in different programming languages, can all access the same application file with no compatibility concerns.
  • Multiple processes can attach to the same application file and can read and write without interfering with each another.
  • Cross-session undo/redo can be implemented using triggers.
  • In many common cases, loading content from an SQLite database is faster than loading content out of individual files. See Internal Versus External BLOBs for additional information.
  • Content stored in an SQLite database is more likely to be recoverable decades in the future, long after all traces of the original application have been lost. Data lives longer than code.
