When multiple users are editing the same data, concurrency effects can result in lost work or errors. This course teaches you how to prevent concurrency errors at database level, and for business transactions that span multiple pages and postbacks.
When developing applications where multiple users can edit the same data, concurrency effects can result in work being overwritten and inconsistent data being read, which can cost a business time, money, and frustration. In this course, Enterprise Patterns: Concurrency in Business Applications, you'll learn how to recognize and prevent these types of errors. First, you'll explore how to use isolation levels within database transactions. Next, you'll discover how to implement optimistic and pessimistic concurrency in code for long-running business transactions. Finally, you'll learn how to design a locking framework for your application. When you’re finished with this course, you'll have a foundational knowledge of concurrency patterns that will help you as you move forward to design more robust, enterprise applications. Software required: Microsoft Visual Studio.

Course Overview [Autogenerated] Hi, everybody. My name is Neil Morsi and welcome to my course enterprise patterns, concurrency and business applications. When more than one user tries to update the same piece of data at the same time, a whole host of concurrency errors can occur like lost updates, Dirty reads and Phantom reads. Not only can users lose work, but strange errors can appear in everything from the user interface to calculations to even reports. If you don't take concurrency into account when designing your application in, this course will examine how to prevent concurrency issues at two levels. At the database level. We'll look at how isolation levels work in system transactions and then, at a higher level, will examine concurrency and business transactions, where user performs operations that's banned multiple pages and post backs before committing their data. If someone else modifies the data during that time, work can get over written and lost. We'll be examining concurrency control for business transactions using design patterns from Martin Fowler's famous book Patterns of enterprise application architecture. The examples in this course air in the latest versions of SB dot net core an entity framework or but these air designed patterns you're gonna learn the concepts really well. So regardless of what language and platform you code in, you'll gain an understanding of how to implement these patterns. Some of the major topics will cover include understanding and recognizing types of concurrency errors. How to handle concurrency at the database level, using transactions and isolation levels, as well as features of entity framework or how to implement optimistic and pessimistic concurrency control. How to handle concurrency for groups of objects like a customer and their addresses, and how to build concurrency control into a framework in your application so you can ensure that you and other developers on your team don't bypass your concurrency strategy. This is a topic that's often overlooked in system design, so knowing these patterns will add to your toolbox and make you a better application. Designer and developer. Well, you don't need any prior experience to follow the concepts and patterns in this course. If you want to get the most out of the demos, you'll need a basic understanding of SP dot net and the entity framework. I'm really excited to show you how you can use these patterns to make your applications more robust so I hope you'll join me on this journey toe learn enterprise patterns, concurrency and business applications here on plural site.
