Practical Entity Framework Core 6: Database Access for Enterprise Applications

Take a developer journey that paves the way to enterprise-level database access from .NET and C# using the object-relational mapper (ORM) of choice. This second edition is revised to cover Entity Framework Core 5 and 6 (EF) and includes new content on table-per-type mapping, LINQ improvements (filtered includes), many-to-many navigation changes, split queries, simple logging using the DBCommandInterceptor, and other improvements available in EF Core 6. Real-world examples and considerations are presented in this book to help you create robust and efficient database solutions. Throughout the text, actual problems, questions, and common pitfalls are provided to help you recognize optimal solutions for maximum success in the different application scenarios you might encounter. Practical Entity Framework Core 6 focuses on the code first approach to developing a database. Taking the code first approach allows the entire database to be built and maintained in code using EF Core 6 so there is never a situation in which you cannot restore the database schema. Additionally, the code first approach creates an entirely transparent record of changes to the database that is easily tracked in source control systems such as GitHub. Emphasis throughout the book is on leaving you well positioned to architect and lead data development efforts for your organization.What You Will LearnBuild robust and maintainable databases using a code first approachCreate and execute stored procedures, triggers, and functionsAnalyze and optimize performance of database queriesEnsure data integrity through keys, constraints, and relationshipsEncrypt your database columns at rest with TDE and Always-On Encryption Leverage the FluentAPI and attributes for entity configurationWho This Book Is For.NET developers who work with enterprise-level applications and need to interact with data structures and data within the back end data store, developers who want to take a code first approach to building database applications to prevent conflicts and optimize efficiency, and those who are moving into full-stack roles, or into senior and architectural roles, and will be responsible for database design and implementation

Modern Data Engineering with Apache Spark

Leverage Apache Spark within a modern data engineering ecosystem. This hands-on guide will teach you how to write fully functional applications, follow industry best practices, and learn the rationale behind these decisions. With Apache Spark as the foundation, you will follow a step-by-step journey beginning with the basics of data ingestion, processing, and transformation, and ending up with an entire local data platform running Apache Spark, Apache Zeppelin, Apache Kafka, Redis, MySQL, Minio (S3), and Apache Airflow.Apache Spark applications solve a wide range of data problems from traditional data loading and processing to rich SQL-based analysis as well as complex machine learning workloads and even near real-time processing of streaming data. Spark fits well as a central foundation for any data engineering workload. This book will teach you to write interactive Spark applications using Apache Zeppelin notebooks, write and compile reusable applications and modules, and fully test both batch and streaming. You will also learn to containerize your applications using Docker and run and deploy your Spark applications using a variety of tools such as Apache Airflow, Docker and Kubernetes.Reading this book will empower you to take advantage of Apache Spark to optimize your data pipelines and teach you to craft modular and testable Spark applications. You will create and deploy mission-critical streaming spark applications in a low-stress environment that paves the way for your own path to production.What You Will LearnSimplify data transformation with Spark Pipelines and Spark SQLBridge data engineering with machine learningArchitect modular data pipeline applications Build reusable application components and libraries Containerize your Spark applications for consistency and reliabilityUse Docker and Kubernetes to deploy your Spark applicationsSpeed up application experimentation using Apache Zeppelin and Docker Understand serializable structured data and data contracts Harness effective strategies for optimizing data in your data lakes Build end-to-end Spark structured streaming applications using Redis and Apache Kafka Embrace testing for your batch and streaming applications Deploy and monitor your Spark applications Who This Book Is ForProfessional software engineers who want to take their current skills and apply them to new and exciting opportunities within the data ecosystem, practicing data engineers who are looking for a guiding light while traversing the many challenges of moving from batch to streaming modes, data architects who wish to provide clear and concise direction for how best to harness and use Apache Spark within their organization, and those interested in the ins and outs of becoming a modern data engineer in today's fast-paced and data-hungry world

Oh God, Why Can't I Stop?

Are You Sick and Tired of Failing? It's frustrating to fail against the sin of this world. It's even worse failing against temptation, fear, and faithlessness as a believer in Christ. You're not alone. Jason Ritchie never felt so "not right" with God as during his biggest failure. He cried out in distress, "Oh God, why can't I stop failing? I can't seem to stop. Though I pray, though I study, though I return to You, I still sin, and I don't want to." In the aftermath, he wondered: "Will You still keep me? Will You still love me? Will You still use me?" What does God say to these questions? "Echoes the heart cry of every Christian who has fallen short of the Holy God we serve. Ritchie artfully applies Scripture as the lens of truth through which the reader is able to see Christ's mercy and grace through our repeated shortcomings." - Dr. Ed Young, Senior Pastor at Second Baptist Church, Houston, Texas Discover God's fundamental response to failure. Oh God, Why Can't I Stop? examines God's fundamental response to failure through the story of Peter's denial of Christ. It explores the Apostle Paul's lament in Romans 7:19: "For I do not do the good I want to do, but the evil I do not want to do-this I keep on doing." This Bible study examines the failures of some of the greatest people in God's family - and eight ways in which many of us fail today: Falling into Depression Hating Judging Others Holding On to Bitterness Lusting Giving In to Gluttony Saying Things I Shouldn't Being Prideful "Guides us with wisdom and grace through various failures. Jason Ritchie diagnoses our struggles, relays real-life and biblically-based advice, is transparent about his own failures, and most importantly offers rich hope to every reader in the forgiving work of Jesus our Savior." - Chad Bird, Scholar in Residence at 1517 Study individually or as a Bible study group. Each chapter concludes with Reflection questions to consider by yourself or as a Bible study group. You'll find out how God responded in each situation - and what it means for us today. "Captures the essence of our failures without pointing the finger of shame or guilt. . . . An eye-opening and heart-wrenching book that can be used individually or in small groups." - Brad Goad, author of The Night He Was Betrayed, Pastor of Adult Bible Study at Second Baptist Church, Houston, Texas It's time to stand on God's Word and move forward. Find out how God's response to failure conquers shame and paves your way to victory.
