I know it's a lot of work to learn initially, but I would recommend
taking the time to install and become familiar with a database engine
such as MySQL or PostgresQL. While SQLite is easy to install and easy to
use, it also cuts a lot of corners and allows you to do things that would
die in a real database. For example, in SQLite column types are merely
suggestions; there is nothing in SQLite to keep you from storing a string
in an integer field or vice versa.
For example:
dan@dan:~/work$ sqlite3
SQLite version 3.7.3
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> create table test (
...> id int,
...> name varchar(64),
...> comment varchar(256)
...> );
sqlite> .schema test
CREATE TABLE test (
id int,
name varchar(64),
comment varchar(256)
);
sqlite> insert into test values (1, 'Dan', 'Normal insert with valid
types');
sqlite> insert into test values ('Bogosity', 2, 'Record with invalid
types');
sqlite> insert into test values ('This field should be an int but is
really a long string instead', 12.45, 'A really screwy record');
sqlite> select * from test;
1|Dan|Normal insert with valid types
Bogosity|2|Record with invalid types
This field should be an int but is really a long string instead|12.45|A
really screwy record
sqlite>
This is not to say that SQLite is useless. Far from it - I use it
frequently myself. But I've been working with SQL databases for a bunch
of years, and I am familiar with the tradeoffs involved in working with
SQLite.
A decent tutorial on working with SQL in general can be found at http://
www.w3schools.com/sql/sql_intro.asp
Installing MySQL or Postgres can be fairly simple, if you use the tools
provided with your Linux distro (assuming you're running on Linux). "sudo
apt-get install mysql mysql-server" or "yum install mysql mysql-server"
should get you what you need to start using MySQL, "sudo apt-get install
postgresql" or "yum install postgresql" should get you started with
PostgresQL.
