Here is a graphical representation of entity framework's code-first approach that helps developers in easily creating classes as the requirement and database is created automatically. these poco data classes (also known as persistence-ignorant objects), which are mapped to entities that are defined in a data model, support most of the same query, insert, update, and delete behaviors as entity types that are generated by the entity data model tools. this means that you can use "plain-old" clr objects (poco), such as existing domain objects, with your data model. The entity framework enables you to use custom data classes together with your data model without making any modifications to the data classes themselves.

this approach enables us to write plain-old" clr objects (pocos) for our models and it helps in making changes to the persistence layer without impacting the models. in this approach, we do not use entity designer (.edmx).

as the name implies, the classes are created first and then database is generated from the classes to fulfill the business needs.

This approach is basically an opposite of data-driven approach and the focus is entities and models which is why it is known as “entity framework code first approach”. these models encapsulate complex business logic, closing the gap between business reality and code.

properly applied it can lead to software abstractions called domain models. On the other hand, many developers are shifting towards the alternative way of developing (and designing) applications by using domain centric approach (domain-driven design).ĭdd is a collection of principles and patterns that help developers craft elegant object systems. in this approach, the entity framework is created from an existing database. many developers still follow this approach and the approach is commonly known as “entity framework database first approach”. hence, the traditional approach in most cases is always about building the application based on the database schema. before we dive deep into the details of code-first approach, we should understand the transference in a way the modern applications are being developed.Ĭonventionally, we have been developing data centric applications where the focus is what data is needed to justify our business needs. in other words, it allows developers to access and store data in the database via an automated mechanism. This and other anomalies make this Caribbean island quite phenomenal, and there are geological structures that you will find only here.Entity framework (ef) is an object relational mapper (orm) that enables developers to work with relational data using domain-specific objects. Geologically Barbados is unique, being actually two land masses that merged together over the years. Within the coral core there is a vast array of caves and underground lakes which provide an excellent supply of drinking water that is amongst the purest in the world. When you visit, you will see it is mostly a flat coral island with excellent beaches, but there are also rolling hills and many deep ridges and gullies, with an interesting distribution of flora and fauna. The constant breeze of the trade winds gives the island a mild and pleasant tropical climate.

Along the East Coast a lively surf is blown briskly by the strong and constant trade winds and the waves pound against a rocky shore. Coral reefs fringe coast providing excellent snorkeling and Scuba Diving. On the West Coast, beaches of fine white sand stretch along a blue-green sea. Barbados is a coral island, pushed out of sea by volcanic activity in a far away time.
