Advanced Data Management
30,40 € *
ggf. zzgl. Versand

Advanced data management has always been at the core of efficient database and information systems. Recent trends like big data and cloud computing have aggravated the need for sophisticated and flexible data storage and processing solutions.This book provides a comprehensive coverage of the principles of data management developed in the last decades with a focus on data structures and query languages. It treats a wealth of different data models and surveys the foundations of structuring, processing, storing and querying data according these models. Starting off with the topic of database design, it further discusses weaknesses of the relational data model, and then proceeds to convey the basics of graph data, tree-structured XML data, key-value pairs and nested, semi-structured JSON data, columnar and record-oriented data as well as object-oriented data. The final chapters round the book off with an analysis of fragmentation, replication and consistency strategies for data management in distributed databases as well as recommendations for handling polyglot persistence in multi-model databases and multi-database architectures. While primarily geared towards students of Master-level courses in Computer Science and related areas, this book may also be of benefit to practitioners looking for a reference book on data modeling and query processing. It provides both theoretical depth and a concise treatment of open source technologies currently on the market.

Designed as a wide-ranging guide to Domain Specific Languages (DSLs) and how to approach building them, this book covers a variety of different techniques available for DSLs. The goal is to provide readers with enough information to make an informed choice about whether or not to use a DSL and what kinds of DSL techniques to employ. Part I is a 150-page narrative overview that gives you a broad understanding of general principles. The reference material in Parts II through VI provides the details and examples you'll need to get started using the various techniques discussed. Both internal and external DSL topics are covered, in addition to alternative computational models and code generation. Although the general principles and patterns presented can be used with whatever programming language you happen to be using, most of the examples are in Java or C#. Product Description When carefully selected and used, Domain-Specific Languages (DSLs) may simplify complex code, promote effective communication with customers, improve productivity, and unclog development bottlenecks. In Domain-Specific Languages, noted software development expert Martin Fowler first provides the information software professionals need to decide if and when to utilize DSLs. Then, where DSLs prove suitable, Fowler presents effective techniques for building them, and guides software engineers in choosing the right approaches for their applications. This book's techniques may be utilized with most modern object-oriented languages; the author provides numerous examples in Java and C#, as well as selected examples in Ruby. Wherever possible, chapters are organized to be self-standing, and most reference topics are presented in a familiar patterns format. Armed with this wide-ranging book, developers will have the knowledge they need to make important decisions about DSLs-and, where appropriate, gain the significant technical and business benefits they offer. The topics covered include: . How DSLs compare to frameworks and libraries, and when those alternatives are sufficient . Using parsers and parser generators, and parsing external DSLs . Understanding, comparing, and choosing DSL language constructs . Determining whether to use code generation, and comparing code generation strategies .

High Quality Content by WIKIPEDIA articles! Ganglia is a scalable distributed system monitor tool for high-performance computing systems such as clusters and grids. It allows the user to remotely view live or historical statistics (such as CPU load averages or network utilization) for all machines that are being monitored.It is based on a hierarchical design targeted at federations of clusters. It relies on a multicast-based listen/announce protocol to monitor state within clusters and uses a tree of point-to-point connections amongst representative cluster nodes to federate clusters and aggregate their state. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization.

Building a GUI Test Automation Framework Using ...
68,00 € *
ggf. zzgl. Versand

GUI test automation is a major challenge for software testing and test automation. Most of the current GUI test automation tools are partially automated. They require the involvement of the users in several stages of the testing process. This research is about developing a framework and an application for user interface testing with the least user involvement. Fully user interface testing that does not need user supervision is not a practical solution. Users can be involved and are required to test some aspects of the user interface validation. GUI?s code has some characteristics that distinguish it from the rest of the project code. Generating test cases from the GUI code requires different algorithms from those usually applied in test-case generation. We developed several GUI test generation automated algorithms that do not need any user involvement and that ensure code or branch coverage in the generated test cases. The test cases are generated from an XML GUI model or tree that represents the GUI structure. GUI execution and verification is accomplished through simulating the user interactions and then comparing the output of the execution to the input.

Logics for XML
49,00 € *
ggf. zzgl. Versand

This work describes the theoretical and practical foundations of a system for the static analysis of XML processing languages. The system relies on a fixpoint modal logic with converse where models are finite trees. This calculus is expressive enough to capture regular tree types along with multi-directional navigation in trees. The decidability of the logic is proved in time 2^O(n) where n is the size of the input formula. XPath expressions and XML schemas are linearly translated into the logic. Based on these embeddings, several problems of major importance in XML applications are reduced to logical satisfiability. The focus is then given to a sound and complete algorithm for deciding the logic, along with crucial implementation techniques for building an effective solver. Practical experiments using a full system implementation are presented. The system appears efficient in practice for several realistic scenarios. The main application of this work is a new class of static analyzers for programs manipulating XML data. Such analyzers allow to ensure at compile-time valuable properties such as type-safety and optimizations, for safer and more efficient XML processing.

Joker: An Animator for Formal Languages
54,90 € *
ggf. zzgl. Versand

This work proposes an application that provides graphical animation for formal specifications using the LTS as input. The application initially supports the languages B, CSP, and Z. However, using a LTS in a specified XML format, it is possible to animate further languages. Additionally, the tool provides traces visualization, the choices the user did, in a graphical tree. The intention is to improve the comprehension of a specification by providing information about errors and animating it, as the developers do for programming languages, such as Java and C++.
