Thanks for pointing out the broken link. I've fixed it now so please try it again.

Hello Mohsin. View the details description for video #10. You will find the download link there which provides the project for this video series which includes sample code for this video, #3.

The first source code download I posted was missing the SQLight database. The below download link has it in the bin folder for debug: www.robertmarquez.com/downloads/MVPDemo20180805(WithSqlLightDB).zip

Hello Luis. The only videos I have using EA are already on RUclips. I created those videos a few years ago to serve as a reference point for me to go back and re familiarize myself on how to use the tool later in the future. There are many videos like it on RUclips as well as several on the EA website. Just type the following search phrase on google: enterprise architect uml tutorial I probably would do more videos if I were to upgrade to version 14 but I am still using version 12 as it still meets all my current needs so I don't think I'll be purchasing an upgrade soon. If you send me a note identifying the kind of system you are trying to represent in a UML diagram I can give it consideration so if I do create another one it can hopefully come close to providing answers to the things you are looking for. For example, indicate if you are trying to create a sequence diagram for a web application processing a sales order or a desktop app performing typical client server CRUD operations etc. If you do this then it will give me an idea if I can create a video that is helpful but keep in mind there is no promise to create anything here.

I will try to make the Visual Studio project and code available this weekend.

The source code up to video number 10 is now available at the following location: www.robertmarquez.com/downloads/MVPDemo20180805(WithSqlLightDB).zip I won't have much time to work on this series for a while

Yes, there will be a video number 11 for this series but due to other activities I am busy with I don't see it being released until probably September this year. I might release other videos this month on other topics I have a more immediate need for but it's too soon to know.

Thanks a lot. Great video series and very well explained. I'm trying download the source code to explore but the available link is dead. Could you please restore the link? Again, thanks.

Thanks for pointing out the broken link. It should work now using the below link: www.robertmarquez.com/downloads/MVPDemo20180805(WithSqlLightDB).zip

Presenter an View are still being worked on. It is going to take more than one video to cover the two. Most likely at least one video covering the first part will be this weekend.

Thanks!

I plan to upload the first part covering the Presenter and View by June 22. We are now coming to an end in this series of videos as the Presenter and View are the last remaining parts. Coverage will include integrating all that has been covered in the past videos with the graphical user interface (GUI). Basically the engine and car frame have been built so now we are just bolting the car body over it. Sounds like minimal work but there is actually a lot to do in getting the user interface operational with the underlying parts that have been built.The primary remaining work is in getting the GUI parts are set up.

Hope to get more on interactions between View and PResenter - like Events, BusinessLogic validation on controls, DataBindings to textBoxes, Comboboxes, etc. And tests for it. Thanks

Hello Pawel. The parts I will be covering are those that were implemented in the demo application. From the items you listed: events, controls, and databindings to textBoxes were implemented in the demo app so you will see that. Business Logic validation was covered in the Service video but I will also cover it again in the View/Presenter set so we can see how the view passes data to the presenter which is then validated by the service layer. I did not use a combo box in my implementation for data input. My example data input uses text boxes. A datagridview was used with binding data to list the departments. I don't know if I'll have time to add a combo box as I have spent far more time on the whole series than I thought I would. Please note that there will be more than one video covering presenter and view. The detail you asked about won't really be shown in Visual Studio probably no sooner than part two of the view/presenter parts.

Hello Pawel. While the service layer does have some method names that match those of the repository, it does not carry out the actual implementation. If you watch video #7, you will see how the Service Class is used to achieve data access operations by calling Repository methods and not by actually performing any database operations. . The actual implementation is in the Repository Class itself which you will see when you watch video #6. The reason this demo application service class is matching repository names only is so the Presenter part of the application goes through the Service class. I don't want the Presenter to communicate with the Repository. The Presenter will have to go through the Service class. This is a personal choice. Others may wish to talk to the Repository directly from the Presenter class. I went through the Service class to minimize code in the Presenter class. In some cases, a request for data from the Repository will require the return information to be transformed into something different like a DTO. I want all data transformations to take place in the Service Class as well rather than the Presenter. I want the Presenter to act as much as possible like a coordinator or foreman. I want the Presenter to focus on directing the work that needs to be done by other objects who have been identified as the labor workers of those tasks. Even so, the Presenter will still have a good amount of code in it to get things done. You can see an published example of a service class communicating with a repository in a book titled: Professional Enterprise .NET Chapter 3 look at the ReturnOrderService class. Keep in mind the video series I am putting together is using a small demonstration application. If it were a larger application requiring a wide variety to data access requests then the limited methods names I am using in the service layer (getall, getbyid, etc.) would not be enough. I would need to use other names in the service such as GetHighestRankDeptInNorthTerritory. So for now it looks like the Service Class is the Repository at a quick glance but it is not. The names it has for now are pass through names to the repository and will definitely not match as more customized data access needs arise.

Hello Pawel. I took a second look at your comment and realize I did not answer the root of your question. You have a very good observation as there is an error in having the IDepartmentRepository (interface file) listed in the DepartmentServices class declaration. I added it there initially so Visual Studio would auto-generate the method stubs for me but I forgot to removed it. I have removed it now and everything still works fine. There have been a few code changes after some of the videos were released so there well be some out of sync code issues. However, I will be releasing the complete code set at the end of the series so no one will need worry about having code from an early video that was later updated. Thanks for pointing out the interface reference that does not need to be there.

Hello Christian. Thank you for watching. Please see the comment I have added which discusses the release of video #5 which I hope covers your comment.

Hello Nelo. Thank you for watching. Please see the comment I have added which discusses the release of video #5 which I hope covers your comment.

Thank you Robert. You explained it brief, well and easy to understand videos. Looking forward to it.
