What you see here is an example of an end-user view of an interaction with the portal. This is a portal solution Sybase is building that will link its partners, customers, and employees together through one interface. All of the major interaction aspects of a portal are implemented in this solution. Ties in “under-the-covers” capabilities.
… we find some fundamental features. The database must be completely self tuning. Adaptive Server Anywhere includes a self-tuning cost based query optimizer. The server automatically gathers statistics on the data as the database is used. It then uses this information to automatically determine the most appropriate access plan for a requested query. The fundamental goal of the optimizer is to minimize the effort that a user must exercise to get good performance from the server. The ASA optimizer is constantly being improved based on feedback from customers. Recently we worked with a customer to enhance the optimizer to better handle their 46 table join ! Another aspect of ASA is that it behaves in many ways like any other piece of software. When the database server requires more disk space for storage of data, then it gets more disk space. The user does not have pre-allocate disk space for the database, this is handled automatically. Also, just like other productivity applications, the user can very easily copy their database to different locations on their disk, or to exchange their database with other users. They can even transfer their database to a completely different operating system and ASA will work. ASA is very easy to install, and can even be integrated with a customer’s application installation.
Adaptive Server Anywhere is designed to be very resource efficient. The server executable is approx. 1 MB, and the server uses only about 2 kBytes per connection. ASA is designed to run on minimal machines, including Windows 3.x machines. Disk space is also minimized. There is only a 1 meg overhead for an ASA database, and the ASA software can occupy as little as 10 megs of disk space. SQL Remote also enhances the resource efficiency of a customer system. SQL Remote users are only connected over the expensive communication system for the time taken to exchange messages, not for those messages to be processed. Another cost saving is the savings from not having to have DBA’s present at all the remote sites.
