Checking Output

//insert/store data into client db
CKi.db.sdb.setData('T00I00', [{id: 1, name: 'Selina'}, {id: 2, name: 'Daliya'}]);
CKi.db.pdb.setData('T00I00', [{id: 1, name: 'Raiyan'}, {id: 2, name: 'Rashid'}]);

//retrieve data from client db
CKi.db.sdb.getData('T00I00');
CKi.db.pdb.getData('T00I00');
