With this book i will be sure to be able to setup up quickly and in the right manner the architecture of my application and avoid lot of time in 'Proof of concept'. By the look at the topics covered, this could be the book that finally fills the gap for first-time users. Would be sharing this with the team as soon as I get hold of it. There's two interesting topics I'd like to learn with this book : First it's the various mapping techniques and then it's the Linq queries. I've been using NHibernate as a dilettante for some time now, either by skimming the internet for information SO, this blog and others but i never sat down with a book on the subject to really delve in.
I've only watched 3. I'm curious to see what the book covers on this subject and what new options may be available in 3. This book would be great opportunity to start with NHibernate. I'm using NHibernate 2. How to create a domain model: I dare to say that I'm quite good at creating domain models, after reading Evans' book and applying the techniques he describes.
NHibernate - Getting Started
However, I'm always interested in this topic. Other authors might come up with new ideas I'd love to get up to speed with Linq to NH. Unit testing the data layer I've my own techniques for unit-testing my NH repositories, but I'm sure there are better ways. Net, and one about Envers Hi Ayende! Is that book the one you'd recommend to the people starting with NHibernate today? I'm preparing for the new project and wanted to consider NHibernate instead of Entity Framework, but I need a good book to get me off the ground quickly and with best practices in mind.
Thanks in advance! Will this book help me get over my extreme frustration at trying to get NHibernate to work with DB2? I got spoiled by the ease of use and the "it just works" nature of Entity Framework 4. NHibernate is like a foreign land to me. Having a clear sum up of the best practices and common pitfalls would most interesting for me. Usually i have a gut feeling my code can be more clear and pragmatic but because of my limited experience with NH the sum up would certainly help a lot! I'd love to learn about how to write efficient unit tests using nhibernate. I'd love to learn about an alternative to ER.
I am most interested in learning how to configure my application in a clear and concise way as well as learning about the common pitfalls to look out for. You can scour the web and find a number of examples to get you started, but it's always nice to learn from the experts what are the gotchas. NET world! I found chapter 4 really interesting "Defining the Database Schema".
In what ways are nhib there for you. Should you create the schema yourself or let nhibernate do it for you. Something really important and interesting in my opinion. Two of the more interesting features are a the introduction of different ways to map the entities, beyond the xml files, and b the use of Linq as an alternative to HQL. Looks like some interesting development in NH3. Mike - I bought the book for myself : I made my boss buy it for the company for everyone else to read after I bought it.

Chapter 11 Common Pitfalls - Things to Avoid looks definitely very interesting from what I can read in the books description. I am also interested in ways of performing entity auditing without the direct use of triggers, or other database specific stuff, if this is covered by the book. The two areas in the book that interest me are those on showcasing common pitfalls and applying different techniques to perform database mappings.
I'm extremely interested in integration tests, I've only done them in Java, and now that I've been dumped into the. I think I'm most interesting in learning about both implementing data validation on the entity level as well as common pitfalls to avoid! I use nhibernate daily in my work project but we did not yet start using LINQ to nhibernate and this is probably the most valuable part for me..
I am especially interested in Chapter 9: Writing Queries. By writing bad queries you can loose so much performance. Would be nice to see how it compares. I've heard good things about the latest versions. Very honest answer! There are a few other reasons as well but you asked "the most"..
To me what interests me the most in the book is the complete sample and comparison to ADO. NET , followed by the common pitfalls. Do I have to create an account there? I've never used NHibernate, so a beginners book is perfect for me. I've taken a brief look at Entity Framework and have been planning on using that for an upcoming project, but it would be nice to get this into guide and compare the benefits of both systems before picking one to use.
NET applications and the relational database. What interests me the most about the book would be having a complete guide that covers the basics all the way up to the advanced topics as there's certain things I haven't had much experience with. The different collection mapping types and when to use them would be the most useful for me. I'd love to have a copy! NET come into mind , but I would be surprised if something like that is covered ;.
Ayende @ Rahien
The book seems to be great source of information about NHibernate showing how to start using the framework and helping to migrate from some other ORMs, telling the longer story how to write better solution based on NHibernate and avoiding common pitfalls in the NHibernate world. I'm interested in learning how to best map against an existing 3rd party vendor schema to write programs which can consume and transform the data into other meaningful elements. Markdown turns plain text formatting into fancy HTML formatting.
Ayende Rahien. You can reach me by: oren ravendb. The most important part to me is LINQ usage and model-first development, since it enables a wide range of different scenarios that change the way you design data access.
For me the most interesting part is where and when to create sessions. Hi Ayende, I'm a student from France.

Hi Ayende, In general there are very interesting chapters in this book Just to say something different than previous comments, I would choose chapter about Unit and Integration tests. Frank, I am sorry, just got clarification back. It is the comments here, not there.

Benefits of GraphQL
Free and open-source software portal. Retrieved And if you eventually need to version your API, you've got a lot more to consider. In GraphQL, we can define Query types in our Schema to retrieve or mutate any combination of types in our system through one endpoint i. Next, we can create a Query type in our schema to fetch any Student or Course.
However, we only need to send them to one endpoint. This can lead to two conditions known as Overfetching and Underfetching. Overfetching simply means the client ends up retrieving more information in some circumstances than is necessary. Consider the Student type above. In a master-detail scenario where we're displaying a list of students, we likely only need their id and name. On the flipside, when an endpoint doesn't provide all of the required data the client is forced to make additional requests to fetch everything it needs.
Let's pretend we have a requirement to display a list of students and their courses. GraphQL at its simplest is about asking for specific fields on objects. This core principle solves both the over- and underfetching problem by giving the client complete control over the data it receives. In our example, we can get the data in a shape we require on the client by submitting a query that looks something like this. Notice how the response looks very similar to the query? With GraphQL, the client knows exactly what to expect based on what it requests.
