What holds the world together – Transactions
Data is everything. Consistent data is more! A transaction is a concept, an attitude, a commitment to consistency. The awareness that the data will usually be around much longer than the applications that collect it.
I would therefore like to take a look with you at how a famous monolith works: How does an (Oracle) database really work? For the transactional handling of data, it has to keep a whole series of promises, most of which can be found in the acronym ACID. This presentation explains this acronym, of course. But also, how the DBMS implements all this technically.
The presentation provides know-how for both cloud and on-premises database systems and is aimed at developers who have always wanted to know why a database backend makes sense at all.
No Hints and Stuff: Classic Oracle Performance Approaches and the Role of AI
Join us for an insightful exploration of Oracle Database performance optimization in the era of artificial intelligence. Are AI-powered assistants and „stacked heuristics“ always a reliable guide, or do they sometimes lead us astray? How can machine learning enhance performance, and what aspects still require manual tuning?
Oracle Database version 23ai brings familiar methodologies alongside innovative techniques. This webinar will revisit foundational concepts—such as parsing strategies, cost estimation, execution plan access methods (including new ones), and profiling tools—while also showcasing the latest advancements in AI-driven optimization.
