Summary: In this book, you'll learn the basics of using Entity Framework the preserbelleodo.gq Entity Data Model template, name it preserbelleodo.gq, and then click . NET Entity Framework Step by Step (Step by Step Developer) [John Paul Mueller ] on your expertise—and teach yourself the fundamentals of the Microsoft ADO.
Net framework 4, but without any runtime advantages over version 4. Version 6. Like ASP. Net Core 1. While EF Core 1.
NET Core 2. NET interfaces to connect to the database when programming against the conceptual schema.
Map provider, a database-specific provider that translates the Entity SQL command tree into a query in the native SQL flavor of the database. It includes the Store-specific bridge, which is the component responsible for translating the generic command tree into a store-specific command tree. EDM parser and view mapping, which takes the SDL specification of the data model and how it maps onto the underlying relational model and enables programming against the conceptual model.
From the relational schema, it creates views of the data corresponding to the conceptual model. It aggregates information from multiple tables in order to aggregate them into an entity, and splits an update to an entity into multiple updates to whichever table s contributed to that entity. Query and update pipeline, processes queries, filters and updates requests to convert them into canonical command trees which are then converted into store-specific queries by the map provider.
Metadata services, which handle all metadata related to entities, relationships and mappings. Transactions, to integrate with transactional capabilities of the underlying store. If the underlying store does not support transactions, support for it needs to be implemented at this layer. Conceptual layer API, the runtime that exposes the programming model for coding against the conceptual schema.
It follows the ADO. NET pattern of using Connection objects to refer to the map provider, using Command objects to send the query, and returning EntityResultSets or EntitySets containing the result. Disconnected components, which locally cache datasets and entity sets for using the ADO.
NET Entity Framework in an occasionally connected environment. Embedded database: ADO.
NET Entity Framework includes a lightweight embedded database for client-side caching and querying of relational data. NET Entity Framework, which simplifies the job of mapping a conceptual schema to the relational schema and specifying which properties of an entity type correspond to which table in the database.
Config box, and enter Entities in the text box as shown in figure 3. Click Next. The Wizard connects to the database and presents a list of the objects that you can include in your model. Use the default namespace called Model. Click Finish. The Wizard now connects to Sybase, deciphers the relationships between these two tables, and then creates a data model based on what it learned.
There are a few important points to bear in mind about the interaction between the Entity Data Model Wizard and Sybase The Wizard must be able to infer primary and foreign keys from your Sybase schema.
Be on the lookout for any diagnostic messages from Entity Framework and related Wizard regarding your database structure. If your Sybase tables use niche data types, such as UDT user-defined types , you may receive some messages from the Entity Framework.

I did learn Entity from this book. One person found this helpful. It is my first development book I bought. I was always a bit skeptic about downloading such book, because technology changes quickly. But I must say that while reading this book, there is an in depth and step by step explanation about the Entity Framework. It guides me through the process and makes it look easy. I created some sample applications while reading the book, to test some of what I learned in reality.
The book seems also a very good reference guide while building your own applications. Paperback Verified download. Key concepts are poorly communicated. Sentence structure lacks formality necessary for computer science concepts. Prose is high school level. Poor editing of tutorial steps. Lehrman sets a high standard and this text does not come close.
I downloadd the ebook version of this book directly from the publisher. Since it was the first book available that covered EF 5 features, and was also a step by step guide, I thought it would be useful to update and augment my knowledge of Entity Framework. I read and worked through the entire book. Overall, the author proceeds in a very step-by-step fashion as the title indicates , and the only item that may be difficult for a beginner is knowing where SQL Server Express stores the.
The author uses a simple Windows Forms application to walk through all of the book's examples. Also, Database First and Code First are given brief treatment; Model First is used for almost all of the examples and topics covered.
The main EF 5 features, such as using Table-Valued Functions, enumerations, and model designer features are covered in some detail, but briefly. The book does discuss important topics such as concurrency, and also has interesting material found in the last section of the book, on working with POCO entities from a Model First perspective , inheritance but not differentiating the types of inheritance that EF offers , and using partial classes to customize basic methods like "SaveChanges ", among other things.
I won't provide a chapter-by-chapter summary, as the table of contents is fairly self-explanatory. I will say that for many chapters, the coverage of the topic is again brief. I don't think a reader of this book could effectively use Entity Framework in a disconnected scenario, or even a web-based scenario.
