Structured Query Language is the standard programming language for managing and manipulating data stored in relational databases. It is used by organizations of all sizes and in various industries to store, retrieve, and analyze data. SQL is essential for working with relational databases because it allows developers and database administrators to create data structures and manipulate data. Scripting is the process of automating a series of tasks. Relational databases support SQL, making it easy for developers, analysts, and administrators to use the same language to work with various relational databases, from PostgreSQL to Oracle.

Understand a new way to model power systems with this comprehensive and practical guide. Graph databases have become one of the essential tools for managing large data systems. Their structure improves over traditional table-based relational databases in that it reconciles more closely to the inherent physics of a power system, enabling it to model the components and the network of a power system in an organic way. The authors’ pioneering research has demonstrated the effectiveness and the potential of graph data management and graph computing to transform power system analysis. Graph Database and Graph Computing for Power System Analysis presents a comprehensive and accessible introduction to this research and its emerging applications. Programs and applications conventionally modeled for traditional relational databases are reconceived here to incorporate graph computing. The result is a detailed guide which demonstrates the utility and flexibility of this cutting-edge technology. Databases play an important role in scientific and non-scientific applications. In power system analysis, equipment such as generators, transmission lines, transformers, loads, shunt capacitors/reactors, circuit breakers, nodes, buses, and their properties are typically organized in structured tables in a database. In power system applications, relational databases are widely used to store and manage power system data and models.

Data envelopment analysis (DEA) is a useful tool for evaluating the performance of homogeneous DMUs, which has been the focus of researchers in recent years. On the other hand, DEA-R is a combination of DEA and Ratio Analysis, which is a hybrid technique for calculating efficiency, ranking DMUs, and finding efficient faces. Therefore, the relationship between DEA and DEA-R, as well as the study of ratio analysis and the difference between the concepts of DEA-R and DEA with ratio data, can provide a suitable field for researchers in the field of evaluating the performance of DMUs. Requirement of the present book is to study the basic concepts of data envelopment analysis, and the chapters of this book are the development of basic DEA models in DEA-R and ratio analysis, which can be used for researchers in the fields of applied mathematics, industrial engineering, management and computer engineering. This book is the effort of the authors’ group in the field of research and implementation of practical projects over many years.
