title: Firebird read-only transaction
body: <p>What is the advantage of using Firebird read-only transaction? I am working with Firebird databases more than seven years. I have never used this option. I am just curious what is typical scenario for this feature? I am working with Firebird 2.5.x but if you have useful insight related to Firebird 3.x (or newer versions) your comments are welcome.</p>
