JavaScript DB API设计

var db; /* don\'t worry about the definition */
var is; /* db functions, don\'t worry about definition */

/* variables from HTTP session,  */
var $session; /* $session == {\"user\": 12345} */

var results = [];

db.put(\"posts\").
        where(\"date\", is.between(\"January 10 2010\", \"December 10 2010\")).
        where(\"author\", is(\"John Doe\")).
        where(\"user\", is($session.user).
        into(results);  

var i;
for(i = 0; i < results.length; i++) {
    alert(\"Result #\" + i + \": \" + results[i].title);
