A high-performance data access layer must resonate with the underlying database system. Knowing the inner workings of a relational database and the data access frameworks in use can make the difference between a high-performance enterprise application and one that barely crawls. This book is a journey into Java data access performance tuning. From connection management, to batch updates, fetch sizes and concurrency control mechanisms, it unravels the inner workings of the most common Java data access frameworks. The first part aims to reduce the gap between application developers and database administrators. For this reason, it covers both JDBC and the database fundamentals that are of paramount importance when reducing transaction response times. In this first part, you'll learn about connection management, batch updates, statement caching, result set fetching and database transactions. The second part demonstrates how you can take advantage of JPA and Hibernate without compromising application performance. In this second part, you'll learn about the most efficient Hibernate mappings (basic types, associations, inheritance), fetching best practices, caching and concurrency control mechanisms. The third part is dedicated to jOOQ and its powerful type-safe querying capabilities, like window functions, common table expressions, upsert, stored procedures and database functions.
"The Life of Samuel Johnson, LL.D." (1791) is a biography of Dr. Samuel Johnson written by James Boswell. It is regarded as an important stage in the development of the modern genre of biography; many have claimed it as the greatest biography written in English. While Boswell's personal acquaintance with his subject only began in 1763, when Johnson was 54 years old, Boswell covered the entirety of Johnson's life by means of additional research. The biography takes many critical liberties with Johnson's life, as Boswell makes various changes to Johnson's quotations and even censors many comments. Regardless of these actions, modern biographers have found Boswell's biography as an important source of information. The work was popular among early audiences and with modern critics, but some of the modern critics believe that the work cannot be considered a proper biography. James Boswell (1740–1795) was a lawyer, diarist, and author born in Edinburgh, Scotland. He is best known for the biography he wrote of one of his contemporaries, the English literary figure Samuel Johnson, which the modern Johnsonian critic Harold Bloom has claimed is the greatest biography written in the English language.
