Well... I'm glad you liked the book, and yes, it needs more examples of what AstDB can do. I'll keep that in mind for the next time we revise the material. > and, although I have shedloads of experience with RDBMSs, this is the > first Berkeley DB I've used. If you're coming from a traditional relational database mindset, the AstDB is going to seem very weak. What I tell people in my training courses is that the AstDB database is simple way of storing key-value pairs. You simply use it to store and organize values, and then retrieve one value at a time. Contrast this with relational databases, where you often run queries that retrieve more than one value at a time, do joins across tables, order and filter the results, etc. Hopefully that helps make things a bit more clear. -- Jared Smith Digium, Inc. | Training Manager _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
