Описание: Data mining from traditional relational databases as well as from non-traditional ones such as semi-structured data, Web data, and scientific databases housing biological, linguistic, and sensor data has recently become a popular way of discovering hidden knowledge.This book on database support for data mining is developed to approaches exploiting the available database technology, declarative data mining, intelligent querying, and associated issues, such as optimization, indexing, query processing, languages, and constraints. Attention is also paid to the solution of data preprocessing problems, such as data cleaning, discretization, and sampling.The 16 reviewed full papers presented were carefully selected from various workshops and conferences to provide complete and competent coverage of the core issues. Some papers were developed within an EC funded project on discovering knowledge with inductive queries.
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: 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.

Описание: Temporal database systems are systems that provide special support for storing, querying, and updating historical and/or future data. Current DBMSs provide
essentially no temporal features at all, but this situation is likely to change soon for a variety of reasons; in fact, temporal databases are virtually certain to become important sooner rather
than later, in the commercial world as well as in academia. This book provides an in-depth description of the foundations and principles on which those temporal DBMSs will be
These foundations and principles are firmly rooted in the relational model of data; thus, they represent an evolutionary step, not a revolutionary one, and they will stand
the test of time. This book is arranged in three parts and a set of appendixes: Preliminaries - provides a detailed review of the relational model, and an overview of the Tutorial D
language; Laying the Foundations - explains basic temporal data problems and introduces fundamental constructs and operators for addressing those problems; Building on the
Foundations - applies the material of the previous part to issues of temporal database design, temporal constraints, temporal query and update, and much more; and, Appendixes -
include annotated references and bibliography, implementation considerations, and other topics. The key features: describes a truly relational approach to the temporal data problem;
addresses implementation as well as model issues; covers recent research on new database design techniques, a new normal form, new relational operators, new update operators, a
new approach to the problem of 'granularity', support for 'cyclic point types', and other matters; and, includes review questions and exercises in every chapter.
The book is
suitable for both reference and tutorial purposes.

Описание: Time and Relational Theory provides an in-depth description of temporal database systems, which provide special facilities for storing, querying, and updating historical and future data. Traditionally, database management systems provide little or no special support for temporal data at all. This situation is changing because: . . Cheap storage enables retention of large volumes of historical data in data warehouses. Users are now faced with temporal data problems, and need solutions . Temporal features have recently been incorporated into the SQL standard, and vendors have begun to add temporal support to their DBMS products . Based on the groundbreaking text Temporal Data & the Relational Model (Morgan Kaufmann, 2002) and new research led by the authors, Time and Relational Theory is the only book to offer a complete overview of the functionality of a temporal DBMS. Expert authors Nikos Lorentzos, Hugh Darwen, and Chris Date describe an approach to temporal database management that is firmly rooted in classical relational theory and will stand the test of time. . This book covers the SQL:2011 temporal extensions in depth and identifies and discusses the temporal functionality still missing from SQL.
Описание: This book presents undergraduate and graduate students with the basic principles and practical guidance for the development of relational databases within the framework of the set processing paradigm.
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: 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.
