// The factory for connecting with SQLite database
|
|
//
|
|
// Advantage of SQLite have no limit ability to store data.
|
|
// It will create the sqlite file that store in the application.
|
|
// Also can store more complex data such as relation between tables.
|
|
//
|
|
// For using sqlite you have to install $cordovaSQLite by running the following
|
|
// command in your cmd.exe for windows or terminal for mac:
|
|
// $ cd your_project_path
|
|
// $ ionic plugin remove io.litehelpers.cordova.sqlite
|
|
// $ ionic plugin add https://github.com/litehelpers/Cordova-sqlite-storage.git
|
|
//
|
|
// For install $cordovaSQLite plugin you also have to install this following plugin to get $cordovaSQLite work :
|
|
// $ ionic plugin add com.ionic.keyboard
|
|
//
|
|
// Learn more about $cordovaSQLite :
|
|
// http://ngcordova.com/docs/plugins/sqlite/
|
|
//
|
|
// The database table of contract will be created in modules.run() method in www/js/app.js file
|
|
//
|
|
// Variable name db come from initialSQLite() in in www/js/app.js file because we need to initial it before we use.
|
|
//
|
|
// object schema of contract data is:
|
|
// [{
|
|
// id: id of contract,
