 Название: Resilient Oracle PL/SQL: Building Resilient Database Solutions for Continuous Operation (2nd Early Release)
Автор: Stephen B. Morris

As legacy and other critical systems continue to migrate online, the need for continuous operation is imperative. Code has to handle data issues as well as hard external problems today, including outages of networks, storage systems, power, and ancillary systems. This practical guide provides system administrators, DevSecOps engineers, and cloud architects with a concise yet comprehensive overview on how to use PL/SQL to develop resilient database solutions. A solid knowledge of relational databases such as, those from Oracle, IBM, Microsoft and others remains a good addition to the IT skillset. The same is true for the open source relational databases, such as, MySQL. Pretty much every developer job I’ve done has required at least some knowledge of SQL. Some jobs have also required knowledge of stored procedure languages, such as, PL/SQL. As you’ll see in the book, there is often a great deal of confusion about the role of SQL and PL/SQL in the context of high level languages, such as, Java, C#, jаvascript, and so on. | |

Census data are widely used by practitioners to understand demographic change, allocate resources, address inequalities, and make sound business decisions. Until recently, projects using US Census data have required proficiency with multiple web interfaces and software platforms to prepare, map, and present data products. This book introduces readers to tools in the R programming language for accessing and analyzing Census data, helping analysts manage these types of projects in a single computing environment. R is one of the most popular programming languages and software environments for statistical computing and is the focus of this book with respect to software applications. This section introduces some basics of working with R and covers some terminology that will help readers work through the sections of this book. The tidyverse ecosystem developed by RStudio is one of the most popular frameworks for data analysis in R and attempts to respond to problems introduced by package fragmentation. The tidyverse consists of a series of R packages designed to address common data analysis tasks (data wrangling, data reshaping, and data visualization, among many others) using a consistent syntax. | |
