The code for phpBB3, which can be downloaded from their site, follows a very sensible design pattern. That is, it abstracts away the database from the rest of the code. Essentially, the application maintains what it calls a "Database Abstraction Layer" DBAL , which provides a uniform set of data tier interfaces to the rest of the application. This allows the application to be flexible, providing specific implementations or drivers for use with different databases.
Indeed, phpBB is one of the only forum software packages to provide support for a wide variety of databases. When an application needs to access or modify data, it calls one or more functions from the DBAL, which, in turn, calls functions from the specific driver. Almost every database product uses its own dialect of SQL. For that reason, there are no specific queries in the application code itself.
Instead, the application asks the DBAL to build the query strings and then execute them against the database. In this manner, different drivers can take care of the appropriate syntax for their respective database. Porting the application over merely consists of creating a similar driver for SQL Anywhere, and then copying the data structure and contents.
For example, if using PHP version 5. This launches the database creation wizard, which will create, tune, and mount the database. Upon successful creation and mounting of the database, it will be ready to receive incoming connections. Go to page: 1 2 Next.

A question I had with the AMI's that aren't launching and that I still have if I just install a server myself is where can I find the costs? I don't mean the base Amazon costs but the Sybase costs. Finally, should I be concerned that the spell check for this forum's editor is flagging "Sybase" as misspelled?
I am happy to try to handle any AWS questions. Certainly if the questions are of general interest, feel free to post them on the forum. If they are more specific, feel free to email me directly at eric dot farrar at sap dot com. This forum is currently your best approach for getting answers for Amazon questions that are specific to Sybase and specifically SQL Anywhere databases. If you make sure to tag them as "Amazon" as this question is , it may help it get answered faster. Just to clarify, the pre-built images that Sybase published back in which were the subject of this question , were for the Developer Edition and Web Edition only.
We had not yet produced any images that included a production license fee. Based on your question, it sounds like this is something you might be interested in. Currently the only way to run a production Sybase database on Amazon is a "bring-your-own-license" model. That is, you purchase a Sybase database license normally, and then choose to run that license on Amazon as opposed to running it on your own hardware. The M1. Large Windows machine.
Everything is working fine with one problem. I placed a shortcut to the server in the Windows Startup folder, but the server is not starting up when the instance starts running. However, at the moment that I connect to the instance with Remote Desktop I see the message "preparing desktop…" and then the server launches automatically. What do I need to do to get the server to launch when the instance starts running so that I don't have to manually connect with Remote Desktop to trigger the startup launch?
In the meantime I will take a look at the on-demand edition; currently we are just running a test server but when we go into production that looks like something we would want to seriously consider. Recently his main interests have shifted from distributed data and synchronization to object-relational mapping from class to database.
