Hello and welcome to our today's article on SQLite which is the most widely deployed SQL database engine in the world that comes with zero-configuration, that means no setup or administration needed. SQLite is public-domain software package that provides relational database management system, or RDBMS that is used to store user-defined records in large tables. In addition to data storage and management, database engine process complex query commands that combine data from multiple tables to generate reports and data summaries.
SQLite is very small and light weight that does not require a separate server process or system to operate. It is available on UNIX, Linux, Mac OS-X, Android, iOS and Windows which is being used in various software applications like Opera, Ruby On Rails, Adobe System, Mozilla Firefox, Google Chrome and Skype.

source='sqlite3.c' object='sqlite3.lo' libtool=yes \
DEPDIR=.deps depmode=none /bin/bash ./depcomp \
/bin/bash ./libtool --tag=CC --mode=compile gcc -DPACKAGE_NAME=\"sqlite\" -DPACKAGE_TARNAME=\"sqlite\" -DPACKAGE_VERSION=\"3.9.1\" -DPACKAGE_STRING=\"sqlite\ 3.9.1\" -DPACKAGE_BUGREPORT=\"http://www.sqlite.org\" -DPACKAGE_URL=\"\" -DPACKAGE=\"sqlite\" -DVERSION=\"3.9.1\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_DLFCN_H=1 -DLT_OBJDIR=\".libs/\" -DHAVE_FDATASYNC=1 -DHAVE_USLEEP=1 -DHAVE_LOCALTIME_R=1 -DHAVE_GMTIME_R=1 -DHAVE_DECL_STRERROR_R=1 -DHAVE_STRERROR_R=1 -DHAVE_POSIX_FALLOCATE=1 -I. -D_REENTRANT=1 -DSQLITE_THREADSAFE=1 -DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_RTREE -g -O2 -c -o sqlite3.lo sqlite3.c
After running make command, to complete the installation of SQLite on ubuntu run the 'make install' command as shown below.
# make install
4) Testing SQLite Installation
To confirm the successful installation of SQLite 3.9, run the below command in your command line interface.

sqlite> create table memos(text, priority INTEGER);
After creating the table, insert some data using the following commands.
sqlite> insert into memos values('deliver project description', 15);
sqlite> insert into memos values('writing new artilces', 100);
To view the inserted data from the table , run the below command.
sqlite> select * from memos;
deliver project description|15
writing new artilces|100
to exit from the sqlite3 type the below command.
In this article you learned the installation of latest version of SQLite 3.9.1 which enables the recently JSON1 support in its 3.9.0 version and so on.
