MySQL 7 - One-to-One Relationship
 
03:36
This video introduces the concept of designing relationships. Now, when we have data that is somehow related, we have a relationship. There are three kinds of relationships: One-to-one One-to-many Many-to-many We are going to discuss each one of these in a separate video. The focus of this video is one to one relationships. Once again we have to go back to the concept of entities and attributes. An entity is something we store data about and an attribute is the data we store about the entity. This is an example of a relationship. That's because the entity and the attributes are connected in that one depends upon the other. We can describe this relationship by saying it is either one-to-one, one-to-many, or many-to-many. Let's go through an example of a user and an email. A specific user has one username. Is this email going to be used by other people? The chances are no. This email is exclusive to this user. This is a great example of a one-to-one relationship. That's because a user has only one email, and an email is used by only one person. To better understand this, let's compare it to a different attribute. Let's say this is a bidding website and users can post junk to sell. So we will say that the user has an attribute of his auctions. Is this a one to one relationship? Well, the item for sale is posted by only one user, but the chances are that the website will allow the user to post multiple items. In this situation, the relationship is not one-to-one. It is actually a one-to-many relationship, which we will discuss in more detail in the next video. So let's disregard the one-to-many relationships until the next video and let's focus on how to design one-to-one relationships. It's actually very easy. Because an attribute of an entity that is one-to-one exclusively describes that entity, all we have to do to design this relationship is store it as a column in a table designed for this entity. We could have a users table that has a column of username. Problem solved. When you hear one-to-one, think "column in a table." There is one other way to store a one to one relationship. Let's say you have to store the user's image in the database. The image is going to be one-to-one relationship, but you could store it in a table called users_image and reference the user that the image belongs to. That way, we have a separation from the image data and the users data and we only need to use the users_image table when we need images. So in conclusion, there are two ways: A column in a table. A table designated for that attribute that refers directly to the entity using a foreign key. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Creating a one to many relationship in a Access 2013 College Database
 
08:00
one to many relationships are the basic relationship of all relational databases. It allows database designers to split different entities of a system into different tables and then relate individual records with others in other tables. It is one of the foundations of relational databases as set out by EF Codd in the 70s.

Entity Relationship Diagram (ERD) Tutorial - Part 1
 
06:58
Learn how to create an Entity Relationship Diagram in this tutorial. We provide a basic overview of ERDs and then gives step-by-step training on how to make an ER diagram with correct cardinality. Entity Relationship Diagrams are comprised of 3 main categories: entities, attributes, and relationships. Entities are objects or concepts that are associated with important data—like a customer, order, or product. Attributes represent properties or traits of an entity, such as a customer’s phone number or home address. Relationships demonstrate the link between entities. Another main aspect of of ERD's is cardinality, which further defines the relationship between entities in a numerical way. Certain symbols signify the minimum and maximum relationship between different entities.

MySQL 8 - One-to-Many Relationship
 
05:12
A One-to-Many relationship is when one side of the relationship is exclusive, but not the other. An example of this given in the last video was a user on a bidding website. The way this app is set up is that the user can post as many items as he wants, but an individual item listing can only be owned by one user. We could say that the listings are an attribute of the user. The incorrect way to store these is to put everything in one table, the users table. Either we will be storing multiple listings in one column, have unneeded columns, or have duplicate data from unneeded extra rows. As you can see, storing one-to-many data is not as easy as creating a column in a table. This calls for a new table. The listings table! This is going to store the data for the listing and also have a column for the owner. The owner is going to be a foreign key to the users table. When we go through an example of data that is stored in this table, you'll see that we've mitigated all of our previous problems when we were trying to store it in one table. So in conclusion, when you have a one-to-many relationships, you take the many side of the relationship, in this case listings, and create a new table for it. You then create a column that references one individual entity from the one side of the relationship, in this case users. Now an important thing for you to understand is that often the relationships in a database can be decided by either you, or the business rules of the database or the application. So in this situation, we have restricted the listings to being owned by only one user. Does it have to be this way? No. This was a decision by us. We could modify the application to allow a listing to be owned by more than one user. This would be introducing co-ownership to the listings inside of to the application. This is something we will do in the next video, so go watch it! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

How to create a one to one relationship in MS Access 2007/2010/2013
 
01:05
This tutorial will show you an example of how to create a one to one relationship in Microsoft Access 2007, 2010 and 2013. -- Please SUBSCRIBE to HandyAndy Tech Tips for more helpful and entertaining videos just like this one! -- TRANSCRIPT: Hi, it's HandyAndy Tech Tips here, and today I'm going to show you how to create a one-to-one relationship in Microsoft Access. So I've got two tables here, CreditCard and Customer. The relationship according to the entity relationship diagram, the ERD, is that one customer can have one credit card, and you can see that I've got a foreign key for the customer in the credit card table. But when I try and create a relationship between these two tables, it defaults to a one-to-many relationship, which is not what I want, and there's no way to change the relationship type from within this dialog. So the solution I found is to right click on the table and click "Table design"; click on the foreign key field; and down here in the field properties, change the Indexed property to "Yes (No duplicates)". Now when you save the table and try to create the relationship again, it should say one to one. I hope you enjoyed this short video; I'm HandyAndy Tech Tips and thanks for watching! -- How to create a one to one relationship in MS Access 2007/2010/2013

10:21
Want to know how to create and diagram a database design one to many relationship? Watch this video to find out. In database design, one to many relationships are the most common type of relationship between tables. They represent records in one table being related to many records in another table. If you’re just getting started with designing your database, you may not know how they fit into your design or how to determine which relationships are on to many. In this video, you’ll learn all about them and how to add them to your design. You’ll learn: What a one to many relationship is in database design How to work out what objects or tables you are actually working with How to determine which way the database design one to many relationship actually goes How to create a standard diagram that shows the one to many relationship between the two tables The diagram you’ll start creating is called an Entity Relationship Diagram, or ERD for short. It’s a standard diagram used to define a database. There are many software tools out there for doing this, but it’s just as easy to do on pen and paper in this video. The video breaks this process down into 7 steps, and includes several examples of this process.

To connect each table, both tables must have something in common. There are two types of relationship, a one to many which works very well in Power Pivot and DAX. Then there is a Many to Many relationship, which can cause problems. In this video we will look at three many to many relationship problems in Excels Power Pivot and how you can easily overcome them. The approach we will take is very systematic. We will build up our data model table by table. This way we can see how additional tables of data, that contain many to many relationships, can effect our pivot table formula. Then we will look at how the problems can be solved.

Building relationships between tables when both have duplicates
 
06:14
PowerPivot and Power BI Desktop only allow the creation of relationships between tables when one of columns forming the relationship does not have duplicate values. In order to relate these two tables to one another, what we need is a third table with all distinct values from both tables. In this tutorial we will show you how to do just that.

Many-to-many Relationships in Access
 
13:31
In reality the relationship between the students table and the courses table is a many-to-many relationship, meaning, a course can be done by many students and a single student can do many courses at the same time. In MS Access you need to handle this relationship carefully by creating a link or join table. What is the job of this extra link table? It converts the many-to-many relation between Access tables into two easy to handle one-to-many relationships. You'll encounter such situations in many domains while creating tables and relationships. Therefore it becomes important to understand the concept thoroughly before moving ahead. Now we use the database tools and its 'relationships' feature for converting the many to many relationship in MS Access to two one-to-many relationships after creating the third table. Once the relationship has been properly converted we can use the power of the relationships to do interesting queries or create forms as shown in the training video. The form, of course, will be discussed in detail in the coming videos. Note here that we generally use forms to enter data into our tables. In this video you'll also understand the importance of 'Enforce Referential Integrity' feature while creating relationships.

SQL Server 9 - Many-to-Many Relationship
 
05:12
In the last video we had an example of a one-to-many relationship for an application that allows users to post blogs. A user could post as many blogs as he wanted, but a blog could be posted by only one user. This design is slightly limiting though. That's because there is a real possibility that a blog could be created by multiple people. This video is going to discuss that design. Which one is the best design? That is a decision that is either up to you, or whoever gives you the requirements of the database. This gives us more capabilities with the cost of added complexity. So we have users, and we have a blogs table. We figured out how to design this as a one-to-many relationship by simply referencing the user in the blogs table. What if we need to reference two users? Well, we have a few options. Let's go through them. The first is to store multiple UserID's in one column. The problem with this is that the data is no longer atomic and we would have to store it as a string. That is a very bad design. The other option is to create a new column for author two. This too is a stupid design because if we have only one author we are going to have a ton of NULLs for this column. The other option is to create a new row that has the other author and repeats the data about the article. This is bad because now we have duplicate data. If you remember the last video, this is the exact same problem we had trying to store the blogs inside of the Users table. Why are we having this problem? With a one-to-many relationship it works fine because a blog is associated directly with one user. With a many-to-many relationship we are trying to force the many inside of the table that is designed to be on the one side of a relationship. The way we fix this is with an intermediary table. An intermediary is a table that goes in between the two tables. Essentially we are converting our many-to-many relationship into two one-to-many relationships. Imagine that this inability to store data correctly causes a conflict between these two tables and the intermediary table comes to the rescue to prevent future conflict. We often call this intermediary table a combination of the two tables. We will go with UserBlogs. By convention I make the first one singular. The columns inside of this table will be two foreign keys. One foreign key will reference the user, and the other will reference the blog. As for the primary key for this table, you can combine both of these columns and say that the combination of these columns has to be unique. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)
