- 2. What is SQLite ? SQLite is an in- process library that implements a self – contained,zero- configration, with server less design.
- 3. What is SQLite ? SQLIt is a relational database management system contained in C library.
- 4. SQLite & SQL Both are entirely different entities. One is db-in-a-single- file solutions (e.g., SQLite, MS Access) other one is a "real" RDBMS (e.g., Oracle, SQLServer, PostgreSQL, MySQL).
- 5. History D. Richard Hipp designed SQLite in May, while he was working for General Dynamics on contract with the United States Navy.
- 6. The design goals of SQLite were to allow the program to be operated without installing a database management system or requiring a database administrator.
- 7. Hipp based the syntax and semantics on PostgreSQL 6.5 documentation. In August 2000, version 1.0 of SQLite was released, with storage based on GNU Database Manager.
- 8. SQLite 2.0 replaced gdbm with a custom B-tree implementation, adding transaction capability. SQLite 3.0, partially funded by America Online, added internationalization, manifest typing, and other major improvements
- 9. In 2011 Hipp announced his plans to add an UnQL interface to SQLite databases and to develop UnQLite, an embeddable document-oriented database.
- 10. Design SQLite library is linked with application program and application Programs uses SQLite’s functionality through function calls.
- 11. SQLite stores the entire database (definitions, tables, indices, and the data itself) as a single cross- platform FILE on a host machine. It implements this simple design by locking the entire database file during
- 12. In SQLite read operations can be multitasked, though writes can only be performed one after another. The access control in SQLite is handled by means of File system permissions.
- 13. SQLite uses PSQL as a reference platform. SQLite does not enforce type checking.
- 14. SQLite does not compete with client/server databases, it competes with fopen()
- 15. “Normal DBs are connected to the system by a network. But SQLite is once linked with C library it works automatically”
- 16. Features Several reads can permit simultaneously Only one read thread is permitted at a time SQLite version 3.7.4 provides a full text search module Version 3.8.2 added support for creating tables without row id, which may provide space and performance improvements SQLite doesn't ensure any relation between or within the columns.
- 17. Today SQLite is widely used with Android Smart phones since it demands much storage memmory and security. Skype is a widely deployed application that uses SQLite.
- 18. Uses SQLite is used in cellphones, set-top boxes, televisions, cameras, watches, remote sensors, and robots. Using SQLite on server machines is success
- 19. SQLite works great as the database engine for most low to medium traffic websites SQLite makes it a good platform for prototyping new, experimental database language features or ideas.
- 21. Conclusion
