SQLite is a lightweight, relational database that is embedded into applications. It was designed to have a small memory footprint and not require administration. SQLite supports basic data types like text, integer, and real numbers. It uses a B-tree disk-based file format for storage. In Android, SQLite is commonly used through objects like SQLiteDatabase, SQLiteOpenHelper, and Cursor to create, open, and query databases. Common SQL commands like SELECT, INSERT, UPDATE, and DELETE can be executed to manage data in SQLite tables.

3. HistoryOfSQLiteDatabase
•SQLite was designed originally on August
2000.
•It is named SQLite because it is very light
weight (less than 500Kb size) unlike other
database management systems like SQL
Server or Oracle.
•SQLite was designed by D. Richard Hipp
for the purpose of no administration required
for operating a program.

5. WhatisSQLITE???
•SQLite is a software library that provides a
relational database management
system(RDMS). The lite in SQLite means
light weight in terms of setup, database
administration, and required resource.
•RDBMS use NORMALIZATION,
•SECURITY INTEGRITY CONSTARINTS
ON TRANSACTION ACID
•SAVED ON ROWS AND COLUMS

6. • SQlite is an open source embedded database
• it is a relational database.
• The Android SQLite Database requires very little
memory (around 250kb), which is available on all
android devices.
•The resulting design goals of SQLite were to allow
the program to be operated without a database
installation or administration.

7. •It’s a light weight database
•Requires very little memory
•An Automatically managed database
The Basic Advantages of
SQLite:

8. •Text(like string) – for storing data type
store
•Integer(like int) – for storing integer
primary key
•Real(like double)- for storing long
values
The SQLite supports only 3
Datatypes:

9. FeaturesOfSQLite
SQLite has the following noticeable
features:
•self-contained(SQLite is a Self
Contained System. SQLite is "stand-alone" or "self-
contained" in the sense that it has very few
dependencies. ... The entire SQLite library is
encapsulated in a single source code file that requires
no special facilities or tools to build.
• server less(No need of Server)
•zero-configuration
• Transactional(SQlite is a transactional database that
all changes and queries are (ACID).

10. Disadvantages
Huge datasets – DB file can’t exceed file
system limit or 2TB.
Access control – we don’t have any user
interface to operate Sqlite database objects
as in MYSQL / SQL Server /Oracle. All the
objects are virtual.

11. SQLite database architecture split into two different
sections named as core and backend.
•Core section contains Interface, Tokenizer,
Parser, Code generator, and the virtual machine,
which create an execution order for database
transactions.
•Backend contains B-tree, Pager and OS interface
to access the file system. Tokenizer, Parser and
code generator altogether named as the compiler
which generates a set of opcodes that runs on a
virtual machine.

14. Specialized Android Objects:-
SqLiteDataBase in order to use the
sqlite database in androird we should
import the package and create an
instance for accessing this library of
Sqlite
SqLiteOpenHelper in Android is A
helper class to manage database
creation and version management. ...
In other
words, SqLiteOpenHelper removes
the effort required to install and
configure database in other systems.
• Cursor The SQLiteDatabase
always presents the results as
a Cursor in a table format that
resembles that of a SQL
database. Cursor is used to get
all table values with column
names and uses to display all
records from the table
• Content Value ContentValues is
a name value pair, used to insert
or update values into database
tables. ... Content
values are used to inset record in
SQLite database ..

16. Examples To Do
Steps in working with Sqlite
database:
 Creating Sqlite Object
Creating Database
Creating Table
Working with Tables

17. Examples To Do
Step:1 Importingpackage
“android.database.sqlite.SQLiteDatabase”.
Step:2 Creatingobject
SQLiteDatabase object name=null;
Creating Sqlite Objects

18. Examples To Do
mydb=openOrCreateDatabase("DatabaseName5
", MODE_PRIVATE,null);
//mydb is sqlite object name .
//DatabaseName5 is nothing but database
name //MODE_PRIVATE is permissions of a table
accessing
Creating Database Name

19. Examples To Do
mydb.execSQL("CREATETABLEIFNOT
EXISTS“ +TableName+" (ColumnName
DataType);");
Creating Table

20. Examples To Do
Create: mydb.execSQL("CREATE TABLE IF NOT
EXISTS “ +TableName+" (ColumnName
DataType);");
Alter: ALTER TABLE TableName RENAME TO
new-table-name
Drop: DROP TABLE TableName
DDL(Create,Alter,Drop)

21. Examples To Do
Select: Cursor c=mydb.rawQuery("SELECT * FROM
"+TableName+" where Name='"+city+"'",null);
Insert: mydb.execSQL("INSERT INTO "+TableName+“
(Name, Area)“ + "VALUES (‘ayesha',‘sql town‘);");
Delete: mydb.execSQL(“Delete"+TableName);
DML(Select,Insert,Delete)

23. Simple Queries
• SQL - "SELECT * FROM ABC;"
SQLite - Cursor c = mdb.query(abc,null,null,null,null,null,null);
• SQL - "SELECT * FROM ABC WHERE C1=5"
SQLite - Cursor c = mdb.query(
abc,null,"c1=?" , new String[ ] {"5"},null,null,null);
• SQL – "SELECT title,id FROM BOOKS ORDER BY title ASC"
SQLite – String colsToReturn [ ] {"title","id"};
String sortOrder = "title ASC";
Cursor c = mdb.query("books",colsToReturn,
null,null,null,null,sortOrder);
