A basic guide on how to use SSMS to create a relational database

Posted on by

SQL Server Management Studio (SSMS) is a powerful tool used for managing SQL Server instances and creating and managing databases. Here is a basic guide on how to use SSMS to create a relational database.

Step 1: Install and Open SQL Server Management Studio

Firstly, download and install SSMS from the official Microsoft website. Once the installation is complete, open SQL Server Management Studio.

Step 2: Connect to Your SQL Server Instance

Upon opening SSMS, you’ll be prompted to connect to a SQL Server instance. If you’re working on a local machine, the server name would typically be “localhost” or the name of your PC. Enter the server name, select the authentication method, enter your credentials if required, and click “Connect”.

Step 3: Create a New Database

Once you’re connected, right-click on the “Databases” folder in the Object Explorer pane on the left side of the window and select “New Database…”.

In the “New Database” window, enter a database name, set the initial size of your database, and then click “OK”. Your new database will now appear in the “Databases” folder in the Object Explorer.

Step 4: Create Tables

Next, we’ll create some tables for our database. Expand your new database in the Object Explorer, right-click on “Tables”, and select “New Table…”.

In the table designer, you can define the columns, data types, and constraints for your table. For instance, let’s create a ‘Users’ table:

  1. In the first row, under “Column Name”, type “UserID”. In the “Data Type” field, select “int”. Check the “Allow Nulls” box to disallow null values.
  2. In the second row, type “FirstName” under “Column Name”, and select “nvarchar(50)” as the data type. This will allow us to store names up to 50 characters long.
  3. Repeat the previous step for a “LastName” column.
  4. Save the table by pressing Ctrl + S, and name it “Users”.

Step 5: Set Primary Key

It’s important to have a primary key for your tables. Right-click on the “UserID” row and click “Set Primary Key”.

Step 6: Create Relationships

If you have multiple tables and you want to create relationships between them, you can do this in the database diagram:

  1. Right-click on “Database Diagrams” and select “New Database Diagram”.
  2. Add the tables you want to create a relationship between.
  3. Simply drag the primary key from one table and drop it onto the relevant foreign key in another table to create a relationship.

You can repeat steps 4 to 6 to create more tables and relationships as needed. Remember to save all changes and regularly check your work.

Step 7: Insert Data

To insert data into your tables, you can write SQL scripts. Right-click your database and click on “New Query”. Then you can write and execute SQL INSERT statements to add data to your tables.

That’s the basic process of creating a relational database using SQL Server Management Studio. You can also use SSMS to query your database, create views, stored procedures, and much more.
