Managing Time in Relational Databases: How to Design, Update and Query Temporal Data introduces basic concepts that will enable businesses to develop their own framework for managing temporal data. It discusses the management of uni-temporal and bi-temporal data in relational databases, so that they can be seamlessly accessed together with current data; the encapsulation of temporal data structures and processes; ways to implement temporal data management as an enterprise solution; and the internalization of pipeline datasets. The book is organized into three parts. Part 1 traces the history of temporal data management and presents a taxonomy of bi-temporal data management methods. Part 2 provides an introduction to Asserted Versioning, covering the origins of Asserted Versioning; core concepts of Asserted Versioning; the schema common to all asserted version tables, as well as the various diagrams and notations used in the rest of the book; and how the basic scenario works when the target of that activity is an asserted version table. Part 3 deals with designing, maintaining, and querying asserted version databases. It discusses the design of Asserted Versioning databases; temporal transactions; deferred assertions and other pipeline datasets; Allen relationships; and optimizing Asserted Versioning databases.

Bitemporal data is coming, and major database management systems are beginning to support it. You need to know what is going on "under the hood" and this book that will make you the expert on bitemporal data that every IT organization should have on its staff.

There's a lot more to bitemporal data than adding a second timestamp to history tables: for example, a temporal update of a single customer in a bitemporal customer table could require up to a dozen physical SQL transactions to complete. Vendors will eventually make it possible to write bitemporal transactions and bitemporal queries, without having to tell the DBMS how to carry them out. "Bitemporal Data" will qualify you to compare and contrast the bitemporal offerings from DBMS vendors.
Includes vendor-neutral explanations of bitemporal concepts and bitemporal functionality, and an unbiased review of the bitemporal offerings from the major DBMS vendors Clarifies business user requests for temporal data by understanding what information bitemporal data provides that other kinds of data - such as data in non-temporal tables, history tables, data warehouses, or fact-dimension databases - do not provide Explains the substantial increase in complexity between as-written temporal transactions and temporal queries, and the physical SQL activity required to carry out those temporal commands

Westwood (or 'Wetwood' as some called it) was the first purpose-built automobile road-racing track in Canada. Its location in Coquitlam on the slopes of British Columbia's coastal mountains meant that it often rained, but the rest of the time it may well have been the most beautiful racing circuit in the world. The track was built and owned by the Sports Car Club of British Columbia. SCCBC members viewed it as a special place where family members of racing enthusiasts grew up over its 32 seasons. The track ran just about any kind of racing that came along for cars, motorcycles and karts, but was best known for its spectacular races for smaller formula cars, Formula Atlantic in particular. Sadly, in 1990 Westwood suffered the common fate of racetracks located near expanding cities world-wide and was converted into a housing development and golf course.

Compiled by a man who has been involved in professional and amateur racing for over 40 years, this book is an invaluable historical study of sports car road racing in Western Canada. After racing at more than 50 facilities, Tom Johnston visited many more in BC and the prairies to document and photograph the lost race tracks, the failed attempts to build new tracks, and the still operating tracks. This book includes Johnston's exploration of racing tracks built over WWII airfields and a detailed look at the long tradition of amateur home built 'specials'.

Ever take a long countryside drive and have it continually spoiled by a quiet relentless fear of the unknown? Join Dan and Dori on their quest to solve a mystery thrust upon them by a loving uncle. This lighthearted tale opens the door to a truth they have mostly evaded. And, while enjoying their time together, they are clearly outside the law and are aware of at least two characters on their tail with intent to trap or hurt. How they cope with the hitchhiker of fears nagging them all the way through scenic miles on back roads is a delightful and intriguing mix. Unexpected events, visits with loved ones, and surprises aplenty keep them at full throttle. It all comes to a very tense and dramatic climax, many unraveled oddities and questions most of us surely face.
