Do agile methods abandon architecture for speed? Do they replace good design decisions with mindless testing? Are agile methods just another way to hack-and-slash systems together without the appropriate discipline, due-diligence, and documentation? In this Keynote our mysterious programming Star describes how the principles of Agile Software Development lead to rich and robust architectures, high degrees of discipline, due consideration of design and architecture, and all appropriate levels of documentation.
A type defines a set of values. Historically we haven't been very good at using encapsulation to ensure that objects stay within that set of values. This presentation introduces a functional approach to Java type design, using Java's new record keyword to guarantee that each constructed object is a legal value. Your code improves dramatically because now you validate the object in one place, at construction. Because record fields are automatically final, an object cannot be morphed into an illegal value. Such a typed object never needs to be re-checked by any function that receives it as an argument or returns it as a result.
Transactions and Concurrency Control are of paramount importance when it comes to enterprise systems data integrity. However, this topic is very tough since you have to understand the inner workings of the database system, its concurrency control design choices (e.g. 2PL, MVCC), transaction isolation levels, and locking schemes. In this presentation, I'm going to explain what data anomalies can happen depending on the transaction isolation level, with references to Oracle, SQL Server, PostgreSQL, and MySQL. I will also demonstrate that database transactions are not enough, especially for multi-request web flows. For this reason, I'm going to present multiple application-level transaction patterns based on both optimistic and pessimistic locking mechanisms.
This time we would like to present a Polish Java Expert. He has been working in the IT industry for over 20 years (database administrator, programmer, architect, manager and "engineer that handles a disastrous situations"). He participated in both small, medium and large projects, carried out in accordance with the principles of "waterfall", Agile, and in the absence of any methodologies - but always with the same, desired result. Believes in the evolutionary nature of programming architecture, in his spare time he explores the issue of complexity theory and systems thinking. With Java Virtual Machine since 1998, he constantly explores the limits of this technology, sharing his knowledge as a speaker, present at conferences at home and abroad.
