title: iphone - open and close sqlite database every time I use it
body: <p>I am writing an iPhone app that uses SQLite.  I am use to opening and closing my connections every time I use a database.  However, I do not know if that is a good practice in the iPhone/SQLite environment.  I want to know if I should open the database 1 time or if it is OK to open and close the database each time I use it.  Please let me know.</p>
