![]() ![]() The ChatGPT is a language model optimized for conversational interfaces. The focus of this post is on ChatGPT and how you can use OpenAI models in conversational interfaces using. If you’re new here, check out our first post where we introduce the series and show you how to get started using OpenAI in. Migrations: EF provides a set of migration commands that can be executed on the NuGet Package Manager Console or the Command Line Interface to create or manage underlying database Schema.Welcome back to this blog series on OpenAI and.Configurations: EF allows us to configure the EF model by using data annotation attributes or Fluent API to override default conventions.Built-in Conventions: EF follows conventions over the configuration programming pattern, and includes a set of default rules which automatically configure the EF model.So, repeated querying will return data from the cache instead of hitting the database. Caching: EF includes first level of caching out of the box.It also provides options to customize transaction management. Transactions: EF performs automatic transaction management while querying or saving data.Concurrency: EF uses Optimistic Concurrency by default to protect overwriting changes made by another user since data was fetched from the database.EF also provides the asynchronous SaveChangesAsync() method. Saving: EF executes INSERT, UPDATE, and DELETE commands to the database based on the changes occurred to your entities when you call the SaveChanges() method.Change Tracking: EF keeps track of changes occurred to instances of your entities (Property values) which need to be submitted to the database.EF also allows us to execute raw SQL queries directly to the database. The database provider will translate this LINQ queries to the database-specific query language (e.g. Querying: EF allows us to use LINQ queries (C#/VB.NET) to retrieve data from the underlying database.It uses this model when querying or saving entity data to the underlying database. Modelling: EF (Entity Framework) creates an EDM (Entity Data Model) based on POCO (Plain Old CLR Object) entities with get/set properties of different data types.Cross-platform: EF Core is a cross-platform framework which can run on Windows, Linux and Mac.It saves data stored in the properties of business entities and also retrieves data from the database and converts it to business entities objects automatically. ![]() The following figure illustrates where the Entity Framework fits into your application.Īs per the above figure, Entity Framework fits between the business entities (domain classes) and the database. It eliminates the need for most of the data-access code that developers usually need to write.” NET developers to work with a database using. Official Definition: “Entity Framework is an object-relational mapper (O/RM) that enables. With the Entity Framework, developers can work at a higher level of abstraction when they deal with data, and can create and maintain data-oriented applications with less code compared with traditional applications. It enables developers to work with data using objects of domain specific classes without focusing on the underlying database tables and columns where this data is stored. Microsoft has provided a framework called "Entity Framework" to automate all these database related activities for your application.Įntity Framework is an open-source ORM framework for. This was a cumbersome and error prone process. NET objects or vice-versa to apply business rules. We used to open a connection to the database, create a DataSet to fetch or submit the data to the database, convert data from the DataSet to. NET 3.5, we (developers) often used to write ADO.NET code or Enterprise Data Access Block to save or retrieve application data from the underlying database.
