In Detail

Oracle Database is one of the most popular databases and allows users to make efficient use of their resources and to enhance service levels while reducing the IT costs incurred. Oracle Database is sometimes compared with Microsoft SQL Server, however, Oracle Database clearly supersedes SQL server in terms of high availability and addressing planned and unplanned downtime. Oracle PL/SQL provides a rich platform for application developers to code and build scalable database applications and introduces multiple new features and enhancements to improve development experience.

Advanced Oracle PL/SQL Developer's Guide, Second Edition is a handy technical reference for seasoned professionals in the database development space. This book starts with a refresher of fundamental concepts of PL/SQL, such as anonymous block, subprograms, and exceptions, and prepares you for the upcoming advanced concepts. The next chapter introduces you to the new features of Oracle Database 12c, not limited to PL/SQL. In this chapter, you will understand some of the most talked about features such as Multitenant and Database In-Memory. Moving forward, each chapter introduces advanced concepts with the help of demonstrations, and provides you with the latest update from Oracle Database 12c context. This helps you to visualize the pre- and post-applications of a feature over the database releases. By the end of this book, you will have become an expert in PL/SQL programming and will be able to implement advanced concepts of PL/SQL for efficient management of Oracle Database.

Style and approach

The book follows the structure of the Oracle Certification examination but doesn't restrict itself to the exam objectives. Advanced concepts have been explained in an easy-to-understand style, supported with feature demonstrations and case illustrations.

This book examines the politics of rural development with special reference to watershed development interventions in the desert province of Rajasthan in India. Watershed development (and rainwater harvesting) is one of the most significant rural development interventions in rainfed areas of India since the early 1990s. A range of developmental actors including the state watershed department, international donors, NGOs and grassroots organisations are involved in sponsoring watershed development projects. Using multi-sited ethnography and conversational interviews with the deliverers as well as recipients of development, the book compares and contrasts the watershed interventions of the state and two different kinds of NGOs in Rajasthan. While conventional studies on watershed development have focused on the evaluation of ‘success’ or ‘failure’ of particular projects, whether implemented by the state or NGOs, the book moves beyond this narrow analytical gaze to look at the roles, agendas and interests of multiple development agencies, often partnering together and sometimes competing with each other as part of, what the author calls, the ‘watershed development regime’.

Taking cue from watershed development and water conservation projects over the last two decades, the book engages with the larger question of ‘how’ of delivering development. It examines the complex processes of cooperation, competition, negotiations, contestations and conflicts between different stakeholders, including the agents of development and differently positioned rural social groups in the context of Rajasthan. The book demonstrates that the recent interventions in watershed development and rainwater harvesting have considerably shaped the politics of development in Rajasthan in a number of ways: by becoming a site for the remaking of the ‘state’ and its internal relations, by disturbing the local hegemony in the countryside, by creating new relations of
