SQLite is a self-contained, serverless relational database management system designed for ease of use without needing a dedicated database administrator. Developed by D. Richard Hipp, it allows applications to manage data in a single cross-platform file, supporting concurrent reads but serial writes. Widely utilized in various devices and applications, including Android smartphones and Skype, SQLite offers a practical solution for low to medium traffic environments.

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.
