DBMS Internals
A. Albano, G. Ghelli
The book presents the basic concepts of classical centralized DBMS implementation. Database systems occupy a central position in our information-based society, and computer scientist and database application designers should have a good knowledge about both the theoretical and the engineering concepts that underline these systems to ensure the desired application performance. The book starts with an analysis of relational DBMS architecture and then presents the main structures and algorithms to implement the modules for the management of permanent memory, the buffer, the storage structures, the access methods, the transactions and recovery, the concurrency, the cost-based query optimization. Finally, an overview of physical database design and tuning is presented.

Decision Support Databases Essentials
A. Albano, S. Ruggieri
In our information-based society one of the most important applications for computers is information storage and management with a DBMS to support organizations both in performing the business and in bringing the business to the Web to allow new routes to market. It is also well known that information overload is a huge challenge for businesses, but it is also an enormous opportunity in making smarter decisions based mainly on data analysis to improve productivity. Consequently, starting from the 1990s another important application of information storage and management to support organizations is analyzing the business with data-driven Decision Support Systems designed for summarizing large amounts of data into a form that is useful and easily interpretable to help managers to analyze the performance of key business processes, worthy of improvement.
