Описание: The first two editions of Inside Relational Databases have both been best sellers. These new editions will also cover the relational database model but will use different engines to illustrate the model. In doing so, readers will be able to apply the model using their preferred database engine. Initially three versions are planned starting with Access, SQL Server and my SQL.The books show just how simple and useful databases can be. No prior knowledge is required i.e. real world examples show how to manage data efficiently. A significant amount of new material is included in the core of the book and particular emphasis is given to showing how to make a database run faster and more efficiently.

Описание: 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.

Описание: The second edition of the best-selling Inside Relational Databases is revised and updated to bring you the most reader-friendly explanation of the relational model and its importance to database designers and builders.Clear explanations make use of examples rather than equations to show you how an understanding of the relational model can make your databases faster, more flexible and thoroughly fit for their purpose.Dr Mark Whitehorn has an extensive understanding of relational database theory and his popular and long running database column in the UK's "Personal Computer World" has already made database theory accessible to thousands.Bill Marklyn has an intimate knowledge of relational databases and was the Development Manager who oversaw the entire design of the first two major releases of Microsoft's highly successful database product, Access.Together they make a great team, illuminating a tricky subject with substance and style.Reviews from the first edition of Inside Relational Databases:"Quite simply - superb. By making relational databases understandable, Mark Whitehorn and Bill Marklyn have achieved far more than most. Making the subject interesting and entertaining as well puts these two authors firmly in a class of their own."- Neil Fawcett, Group Technical Editor, VNU Business Publications"PCW and Amazon.co.uk contributor Mark Whitehorn is that rare combination - an expert in his field, databases, and a fine writer too, with a talent for honing a complex subject down to its essentials."- Tamsin Todd, Computer & Internet Editor, Amazon.co.uk"Inside Relational Databases is excellent. It is clearly and concisely written and full of humorous asides which ease the reader through an otherwise weighty topic. Probably the most engaging technical book I have read."- Paul McGowan
Описание: Through many examples of good database design, this book shows that relational databases are the best way to store, search, and act on chemical information. Introducing the concepts of RDMS and SQL, the author describes how relational data tables and new data types help store and use chemical information, how molecular structures can become a new data type in a database, and how client programs can effectively use relational databases. He also explains how a fully functioning chemical relational database system can be built. A supplementary website offers an implementation of every function from the book, a database of structures and data, and examples used in the book.
Описание: Information Modeling and Relational Databases, Second Edition, provides an introduction to ORM (Object-Role Modeling)and much more. In fact, it is the only book to go beyond introductory coverage and provide all of the in-depth instruction you need to transform knowledge from domain experts into a sound database design. This book is intended for anyone with a stake in the accuracy and efficacy of databases: systems analysts, information modelers, database designers and administrators, and programmers. Terry Halpin, a pioneer in the development of ORM, blends conceptual information with practical instruction that will let you begin using ORM effectively as soon as possible. Supported by examples, exercises, and useful background information, his step-by-step approach teaches you to develop a natural-language-based ORM model, and then, where needed, abstract ER and UML models from it. This book will quickly make you proficient in the modeling technique that is proving vital to the development of accurate and efficient databases that best meet real business objectives.

Описание: Since databases are the primary repositories of information for today’s organizations and governments, database security has become critically important. Introducing the concept of multilevel security in relational databases, this book provides a comparative study of the various models that support multilevel security policies in the relational database—illustrating the strengths and weaknesses of each model.Multilevel Security for Relational Databases covers multilevel database security concepts along with many other multilevel database security models and techniques. It presents a prototype that readers can implement as a tool for conducting performance evaluations to compare multilevel secure database models.The book supplies a complete view of an encryption-based multilevel security database model that integrates multilevel security for the relational database with a system that encrypts each record with an encryption key according to its security class level. This model will help you utilize an encryption system as a second security layer over the multilevel security layer for the database, reduce the multilevel database size, and improve the response time of data retrieval from the multilevel database. Considering instance-based multilevel database security, the book covers relational database access controls and examines concurrency control in multilevel database security systems. It includes database encryption algorithms, simulation programs, and Visual studio and Microsoft SQL Server code.
Описание: During the last few years, parallel object-relational database management systems have emerged as the leading data management technology on the market. These systems are extensible by user-defined data types and user-defined functionality for the data. This work focuses on the efficient parallel execution of user-defined functionality. The main contributions describe techniques to support data parallelism for user-defined scalar and aggregate functions and intra-function parallelism for the execution of a scalar function on a large object, and a new technology to provide extensibility with regard to new set-oriented database operations that can efficiently implement user-defined functionality in parallel object-relational database management systems.
