--C. J. Date Three decades ago relational technology put the database field on a sound, scientific foundation for the first time. But the database industry--vendors, users, experts, and the trade press--has essentially flouted its principles, focusing instead on a cookbook, product-specific approach, devoid of conceptual understanding. The consequences have been costly: DBMS products, databases, development tools, and applications dont always perform up to expectation or potential, and they can encourage the wrong questions and provide the wrong answers. Practical Issues in Database Management is an attempt to remedy this intractable and costly situation. Written for database designers, programmers, managers, and users, it addresses the core, commonly recurring issues and problems that practitioners--even the most experienced database professionals--seem to systematically misunderstand, namely: *Unstructured data and complex data types *Business rules and integrity enforcement *Keys *Duplicates *Normalization and denormalization *Entity subtypes and supertypes *Data hierarchies and recursive queries *Redundancy *Quota queries *Missing information Fabian Pascal examines these crit

Over the past 10 years, distributed systems have become more fine-grained. From the large multi-million line long monolithic applications, we are now seeing the benefits of smaller self-contained services. Rather than heavy-weight, hard to change Service Oriented Architectures, we are now seeing systems consisting of collaborating microservices. Easier to change, deploy, and if required retire, organizations which are in the right position to take advantage of them are yielding significant benefits.This book takes an holistic view of the things you need to be cognizant of in order to pull this off. It covers just enough understanding of technology, architecture, operations and organization to show you how to move towards finer-grained systems.
