This easy-to-read textbook/reference presents a comprehensive introduction to databases, opening with a concise history of databases and of data as an organisational asset. As relational database management systems are no longer the only database solution, the book takes a wider view of database technology, encompassing big data, NoSQL, object and object-relational and in-memory databases. The text also examines the issues of scalability, availability, performance and security encountered when building and running a database in the real world. Topics and features: presents review and discussion questions at the end of each chapter, in addition to skill-building, hands-on exercises; introduces the fundamental concepts and technologies in database systems, placing these in an historic context; describes the challenges faced by database professionals; reviews the use of a variety of database types in business environments; discusses areas for further research within this fast-moving domain.

Databases pervade our everyday life, they are involved in the individual's most fundamental activities. Through their near invisibility and resistance to narration they produce subtle forms of collective control and normalization, accompanied by keywords such as: mass surveillance, big data, user generated content, etc. The publication "Search Routines: Tales of Databases" enlarges on the topics discussed in the exhibition, the workshop and during the symposium which took place at D21 Kunstraum and sublab hackerspace Leipzig in 2014. A series of interviews review artistic strategies like narration or the translation of data and algorithms to adress the invisibility of databases. Reports from the workshops tell about the potential of making the invisible visible or simply of hiding oneself from the databases' range of view. The symposium dis

Excerpt from Context Interchange: Overcoming the Challenges of Large-Scale Interoperable Database Systems in a Dynamic Environment Research in database interoperability has primarily focused on circumventing schematic and semantic incompatibility arising from autonomy of the underlying databases. We argue that, while existing integration strategies might provide satisfactory support for small or static systems, their inadequacies rapidly become evident in large-scale interoperable database systems operating in a dynamic environment. The frequent entry and exit of heterogeneous interoperating agents renders "frozen" interfaces (e.g., shared schemas) impractical and places an ever increasing burden on the system to accord more flexibility to heterogeneous users. User heterogeneity mandates that disparate users' conceptual models and preferences must be accommodated, and the emergence of large-scale networks suggests that the integration strategy must be scalable and capable of dealing with evolving semantics. As an alternative to the integration approaches presented in the literature, we propose a strategy based on the notion of context interchange. In the context interchange framework, assumptions underlying the interpretations attributed to data are explicitly represented in the form of data contexts with respect to a shared ontology. Data exchange in this framework is accompanied by context mediation whereby data originating from multiple source contexts is automatically transformed to comply with the receiver context. The focus on data contexts giving rise to data heterogeneity (as opposed to focusing on data conflicts exclusively) has a number of advantages over classical integration approaches, providing interoperating agents with greater flexibility as well as a framework for graceful evolution and efficient implementation of large-scale interoperable database systems Keywords: context interchange, heterogeneous databases, semantic interoperability, shared ontology.

This book is about syntactic databases (a.k.a. treebanks), collections of text material in which the syntactic relations have been made visible. It starts off with a general intro-duction to the subject and then continues with three in-depth investigations of more specialized aspects. In the introduction, syntactic databases are first placed in the larger context of linguistic databases, text collections with a broader linguistic annotation than just a syntactic one. Then some examples of syntactic databases are given, illustrating the range of annotation actually encountered. The introduction is completed with an investigation of database management systems for syntactic databases. The first in-depth investigation concerns the treatment of ambiguous structures in syntactic analysis trees, focussing on a very efficient representation for such structures and the means to create this representation. Next, classroom use of syntactic databases is examined. A computer program for this purpose, CLUES, is discussed, along with a suggested series of syntax exercises. The final subject is the importance of including function and attribute information in the annotation of texts. The central line of investigation here is a probabilistic parsing experiment in which the use of function and attribute information is the main variable.

The Internet and the worldwide web play an increasingly important role in our private and professional activities, for example in accessing information about cultural, political, economical, medical or scientific information. Many people assume that they can access such information privately. This book addresses the topic of querying information privately in a systematic and comprehensive way, developing practical solutions in the context of database systems. Based on thorough theoretical analyses, the author develops concepts for solutions of real-world settings, in particular for scalable database systems.

Database transformations consist of queries and updates which are two fundamental types of computations in any databases - the first provides the capability to retrieve data and the second is used to maintain databases in light of ever-changing application domains. This dissertation aims to lay down the foundations for establishing a theoretical framework of database transformations in the context of complex-value databases. The previous findings reveal that it is very difficult to characterise common features of database queries and updates in a way which is meaningful for further investigations. Nevertheless, the advent of the sequential Abstract State Machine (ASM) thesis capturing sequential algorithms sheds light on the study of database transformations. Observing that the class of computations described by database transformations may be formalised as algorithms respecting database principles, we propose the database ASM thesis for a complete characterisation of database transformations. It turns out that every database transformation characterised by five postulates can be behaviourally simulated by a database Abstract State Machine (DB-ASM) with the same signature and background, and vice versa. Furthermore, a logic for DB-ASMs is defined. In spite of bounded non-determinism permitted by DB-ASMs, the logic is proven to be sound and complete.

Context Mediation is a field of research that is concerned with the interchange of information across different environments, which provides a vehicle to bridge semantic gaps among disparate entities. Knowledge Discovery is concerned with the extraction of actionable information from large databases. A challenge that has received relatively little attention is knowledge discovery in a highly disparate environment, that is multiple heterogeneous data sources, multiple domain knowledge sources and multiple knowledge patterns. This thesis tackles the problem of semantic interoperability among data, domain knowledge and knowledge patterns in a knowledge discovery process using context mediation. All presented techniques, methods and models are applied in real-world scenarios, covering disciplines from a wide range of industry, namely web mining and marketing, manufacturing, meteorology and internationalisation. When feasible, industry standards were utilised, for instance ODMG, PMML and KQML. The carried out research has resulted in almost fifty international publications, including the co-authorship of a book, a journal editorship and one conference best paper award.
