What is the difference between dataset and entity data model

With datasets you can create a custom query for your DataTableAdapter in DataSet Designer , and use it to fill your table. I don't think that creating a custom query method using GUI Wizard which can be done with couple of clicks is so difficult that you call this «I need to write custom procedures».

DataSets are quite easy-to-use in this scenario. I know that I answer your question 4 years after you asked, but probably even if it won't be useful to you , maybe it'll help someone who reads this.

For example, using datasets I can have TableName. Field which seems to be exactly the same as with the Entity Framework. What's the difference and why should I use one or the other? This includes the entire data model, which may include more than one table.

Once you import a Dataset - that's it. This works the other way around too. If you already have a connection to anything, like an Excel file for example, you cannot create a connection to a Power BI Dataset. Alien Tip: That's one of the key differences between Datasets and Dataflows. Where Datasets provide an unchangeable data model, Dataflows provide a pre-prepared, modifiable table called "entities" for your existing desktop data model.

He does an excellent job of explaining everything you need to know about getting started all the way to execution. I do want to leave you with this In order to use Dataflows, you'll need either a Pro or Premium license. They also need to be created in the App Workspace, not the "My Workspace".

Nice, neat, and efficient. Along comes the Entity Data Model. The wizard can go through and create a model based on selected tables, if you choose, or you can custom write them.

I get that you can create an Entity that essentially does away with join statements and that seems cool. But every tutorial I have seen so far indicates you have to create a class and custom write all of the CRUD statements for every single operation, pointing each one of them to the EDM. I'm hoping that I'm just missing some vital piece of information that ties everything together and makes EDM way easier to implement than it sounds.

Or is the bottom line that either one works and it's just a matter of personal preference which you use? They're all good technologies for data access in. Typed dataset is an old one and for now, ADO.
