This textbook examines database systems from the viewpoint of a software developer. This perspective makes it possible to investigate why database systems are the way they are. It is of course important to be able to write queries, but it is equally important to know how they are processed. We e.g. don’t want to just use JDBC; we also want to know why the API contains the classes and methods that it does. We need a sense of how hard is it to write a disk cache or logging facility. And what exactly is a database driver, anyway? The first two chapters provide a brief overview of database systems and their use. Chapter 1 discusses the purpose and features of a database system and introduces the Derby and SimpleDB systems. Chapter 2 explains how to write a database application using Java. It presents the basics of JDBC, which is the fundamental API for Java programs that interact with a database. In turn, Chapters 3-11 examine the internals of a typical database engine. Each chapter covers a different database component, starting with the lowest level of abstraction (the disk and file manager) and ending with the highest (the JDBC client interface); further, the respective chapter explains the main issues concerning the component, and considers possible design decisions. As a result, the reader can see exactly what services each component provides and how it interacts with the other components in the system. By the end of this part, s/he will have witnessed the gradual development of a simple but completely functional system. The remaining four chapters then focus on efficient query processing, and focus on the sophisticated techniques and algorithms that can replace the simple design choices described earlier. Topics include indexing, sorting, intelligent buffer usage, and query optimization. This text is intended for upper-level undergraduate or beginning graduate courses in Computer Science. It assumes that the reader is comfortable with basic Java programming; advanced Java concepts (such as RMI and JDBC) are fully explained in the text. The respective chapters are complemented by “end-of-chapter readings” that discuss interesting ideas and research directions that went unmentioned in the text, and provide references to relevant web pages, research articles, reference manuals, and books. Conceptual and programming exercises are also included at the end of each chapter. Students can apply their conceptual knowledge by examining the SimpleDB (a simple but fully functional database system created by the author and provided online) code and modifying it.
Giving comprehensive, soup-to-nuts coverage of database administration, this guide is written from a platform-independent viewpoint, emphasizing best practices.

When it comes to choosing, using, and maintaining a database, understanding its internals is essential. But with so many distributed databases and tools available today, it’s often difficult to understand what each one offers and how they differ. With this practical guide, Alex Petrov guides developers through the concepts behind modern database and storage engine internals. Throughout the book, you’ll explore relevant material gleaned from numerous books, papers, blog posts, and the source code of several open source databases. These resources are listed at the end of parts one and two. You’ll discover that the most significant distinctions among many modern databases reside in subsystems that determine how storage is organized and how data is distributed. This book examines: Storage engines: Explore storage classification and taxonomy, and dive into B-Tree-based and immutable Log Structured storage engines, with differences and use-cases for each Storage building blocks: Learn how database files are organized to build efficient storage, using auxiliary data structures such as Page Cache, Buffer Pool and Write-Ahead Log Distributed systems: Learn step-by-step how nodes and processes connect and build complex communication patterns Database clusters: Which consistency models are commonly used by modern databases and how distributed storage systems achieve consistency

The high failure rate of enterprise resource planning (ERP) projects is a pressing concern for both academic researchers and industrial practitioners. The challenges of an ERP implementation are particularly high when the project involves designing and developing a system from scratch. Organizations often turn to vendors and consultants for handling such projects but, every aspect of an ERP project is opaque for both customers and vendors. Unlocking the mysteries of building a large-scale ERP system, The Adventurous and Practical Journey to a Large-Scale Enterprise Solution tells the story of implementing an applied enterprise solution. The book covers the field of enterprise resource planning by examining state-of-the-art concepts in software project management methodology, design and development integration policy, and deployment framework, including: A hybrid project management methodology using waterfall as well as a customized Scrum-based approach A novel multi-tiered software architecture featuring an enhanced flowable process engine A unique platform for coding business processes efficiently Integration to embed ERP modules in physical devices A heuristic-based framework to successfully step into the Go-live period Written to help ERP project professionals, the book charts the path that they should travel from project ideation to systems implementation. It presents a detailed, real-life case study of implementing a large-scale ERP and uses storytelling to demonstrate incorrect and correct decisions frequently made by vendors and customers. Filled with practical lessons learned, the book explains the ins and outs of adopting project methodologies. It weaves a tale that features both real-world and scholarly aspects of an ERP implementation.

This paper is the product of a collaboration between the Food and Agriculture Organization of the United Nations (FAO) and Wageningen University and Research (WUR) to explore the potential application of innovative technologies to improve data collection and risk estimation of child labour in the cocoa sector. In particular, it assesses the potential role of blockchain technology and Geographic Information Systems (GIS) in collecting and sharing data on cocoa-growing areas in Ghana, and how this could contribute to monitoring and ultimately preventing child labour in those areas. During an inception mission undertaken by FAO in Ghana, open consultations with various stakeholders in the cocoa sector led to the identification of a number of Key Data Elements (KDEs) to inform the design of a blockchain system, with the objective to facilitate real-time, cost-efficient and collaborative monitoring of the risk of child labour in cocoa-growing areas in Ghana. WUR was commissioned by the FAO to further explore the potential application of blockchain technology and GIS to monitor selected KDEs related to the root causes of child labour in Ghana. Despite decades of interventions since the ratification of the Harkin-Engel Protocol in 2001 to eliminate child labour in the cocoa sectors of Côte d'Ivoire and Ghana, the latest progress report shows child labour in this sector is increasing rather than decreasing (Sadhu et al., 2020). This trend is concerning, given the detrimental effects of child labour on children’s lives, education and health and the perpetuated cycle of poverty as a result. To break this trend, it is necessary to expand and improve current methods of tracking the incidence of child labour (monitoring) and explore more sustainable ways to support rural families to keep children out of child labour (prevention). To that end, technology, digitalization, and digital innovations have a role in poverty reduction and improving living standards in developing countries, however, political and socio-economic problems can hinder these technological fixes. With smallholder cocoa producers being the most vulnerable actors within this value chain, the implementation of technological monitoring systems is not a clear-cut route. Participation and engagement depend not only on the perception of the advantages to farmers and community, but also on issues that impact the adoption and use of information and communication technologies (ICT). For example, availability, affordability, and literacy and effective use.
