Hey guys, Wes here. So, I don't know about you guys, but I think the first place. I ever used the internet was at the library

程度の副詞

library management system in ASP.NET Core MVC

Make a series of videos documenting that project so you guys could follow along and we could do some full stack development

We're going to do everything from setting up and designing the database

to implementing the MVC pattern and then finally playing around with some front-end stuff like DataTables (.js)

and maybe some Material Design and Bootstrap

So yeah, the project was kind of fun, and I thought it might be something that you guys would be interested in checking out

Okay, so let's take a look at the software we'll be building over the course of the next several videos

So we have here an integrated library system for a fictional library called Lake View

So an integrative library system also sometimes called a library management system is the software that a library uses to

As they're lent out to various patrons who might sign up for a library card

within that system. So - the library is going to control

You know it's books, magazines - things like that

so it's going to need to manage all of its inventory and

sort of control, you know, how it lends out to its various patrons and to keep track of what patrons have what assets and

what patrons have certain items on hold, for instance.

It's also going to want to track the different branches that belong to that library, so if you live,

for example, in a larger city or region, then your library system might consist of multiple branches

Let's take a look first of all at our library catalog

So you'll see here that we just have a list of assets very simply in a table here

And so we're going to have like the title of whatever the past that is in this case. We'll have a lot of books

The author or director, and then a do we call number, so if the library's going to do a decimal system

This is just a way that they index their books yeah, we can see that the books all have covers

And if they don't we have no cover available icon here

So if we click on one of the books we get taken to a detail page here

so we have a lot more Metadata on this book that we can see so we've got an iSbn for instance a

Call number again. This is the Dewey call number the cost of this asset

What it is so if it's a book or a video or anything?

Its last location so the answers will be associated with a particular Branch

what patrons have checked out this item in the past and over what period of time and

Then also a list of current holds so look at what that means in here in a second

So let's say I wanted to check this book out so I just click here

and then we supply a library card id to which we to check out the book and

now we can see that the book is no longer available, but it has been checked out by this patron and

We can see now that we have a new checkout history started in the table here as well

So the book hasn't been returned yet, but it was checked out this time on this date

So now let's say that I'd like to check the book out, but I'm another patron

and of course it's not available for checkout yet, but I can place a hold will click place hold here and

library card Id here and we'll place a hold and

So now we'll see that this patron has a hold on the item and again other customers can continue placing

Hold and so we'll basically have a queue here of hold so that when our

Customer tomas here checks the item back in

it gets checked out automatically to the first person who had a hold on it a new checkout history record is created and

The Q obviously drops one of the patrons so again if this is checked in by Mary Lee

Is now automatically checked out and if you checked it in

The book is back to being available for checkout. We can also very simply mark it mark the item is lost

Not at which point. It can't be checked out can Margaret sound again

So that's our kind of simple check-in checkout system

We can see how we can manage different patrons that are in our system, so we can see their overdue fees

What library cards are associated with what library branch there so sid live if we click on one of the customers here?

It's an explanation that they might supply when they sign up for a library card

as well as the current items they have checked out and any assets that they have placed a hold on we can also see if

The customer has any fees on their account

It will show up and read on their profile page here

So we can see that this customer has fees due and then so we can base some logic on this and say

Like if the customer has a certain amount of seeds on their account

They might not be able to check out a book or a video just a small other feature we have here some other information

We have on our patron object and finally if we take a look over at our branches page. We have another list view here

Where we have some data about the branch how many patrons are associated with a number of assets that are associated with it?

And if we click on it, we can see a picture

It's scheduled so the dates between which the branch is open

the Total value of the Assets owned by the Branch and some more data so like the description and

some sort of profile data on this particular branch and so each of the branches will have its own sort of profile page and

So yeah, this is our simple integrated library system or library management system, and it's kind of fun to build it's pretty straightforward application

but it's actually it would be a fairly decent starting point for an

Actual system that managed sort of any type of inventory or any type of check-in checkout system. Where you have patrons?

Various locations and various assets to control so I think it's kind of a good general purpose project

Particularly if you are interested in learning about the MVC pattern or just diving into some net

okay, so I have visual Studio open here and

So we'll go ahead and create a new project. So just file new project and

we're going to create an asp.net core web application and

I'm just going to call it library, and I'll place this in a projects directory that I have here

We'll make sure that it creates a new git repo and creates a directory for the solution

So we'll select ok and it's going to ask us if we'd like to use a template and we're going to use the web

application template which is going to allow us to create an asp.net core application with

Okay, so you can see that by default here with this template

we have a project structure in place already, and if you've developed in asp.net before this may look a little bit different to you if

you're coming to dotnet core for the first time so

Something that you'll notice here. Is that we have a wwe?

And that's going to contain all of our static files so csS images Javascript

Third-Party libraries, and you can see that the template has brought in jquery and bootstrap, and yeah

So we can actually use this directory to serve up our static files

When it comes time to load some of those a little bit later, and then we have directories for our

so the template has provided us with the home controller and

Some views for the home controller here as well as some shared views so a layout and a narrow page here

So the layout that's the htML. This is actually going to be shared by all the other views in our system, and so you'll see
