Some common relational database management systems that use SQL or Oracle, Sybase, Microsoft SQL server etc. If you are struggling with How to create a sql database then follow the given steps.
Steps – How to create a sql database
Creating database in SQL server:
Install the SQL server management studio software. This software is available for free from microsoft and allows to connect and manage SQL server from a graphical interface.
The second step in How to create a sql database is to Start up SQL Server management Studio: Starting of the program, you will be asked what server you would like to connect to. If you already have a server up and running, and have the permissions necessary to connect to it, you can enter the server address and authentication information. If you want to create a local database, set the Database Name to . and the authentication type to “Windows Authentication”.
Locate the Database folder:After the connection to the server, either local or remote, is made, the Object Explorer window will open on the left side of the screen. At the top of the Object Explorer tree will be the server you are connected to. if it is not expanded, click the “+” icon next to it. Located the Databases folder.
Next step in How to create a sql database is to Create a new database:Right-click on the Databases folder and select “New Database…”. A window will appear, allowing you to configure the database before creating it. Give the database a name that will help you identify it. Most users can leave the rest of the settings at their default. You will note that as you type the database name, two additional files will be created automatically: the Data and the Log file. The data file houses all of the data in your database, while the log file tracks changes to the database.
Click OK to create the database. You will see your new database appear in the expanded Database folder. It will have a cylinder icon.
Next step in How to create a sql database is to Create a table:A database can only store data if you create a structure for that data. A table holds the information that you enter into your database, and you will need to create it before you can proceed. Expand the new database in your Database folder, and right-click on the Tables folder and select “New Table…”.
Windows will open on the rest of the screen which will allow you to manipulate your new table.
Create the Primary Key: It is highly recommended that you create a Primary Key as the first column on your table. This acts as an ID number, or record number, that will allow you to easily recall these entries later. To create this, enter “ID” in the Column Name field, type int into the Data Type field, and uncheck the “Allow Nulls.” Click the Key icon in the toolbar to set this column as the Primary Key.
You don’t want to allow null values because you always want the entry to be at least “1”. If you allow nulls, your first entry will be “0”.
In the Column Properties window, scroll down until you find the Identity Specification option. Expand it and set “(ls Identity)” to “Yes”. This will automatically increase the value of the ID column for each entry, effectively automatically numbering each new entry.
Next step in How to create a sql database is to Understand how tables are structured:Tables are composed of fields or columns. Each column represents one aspect of a database entry. For example, if you were creating a database of employees. You might have a “FirstName” column, a “LastName” column, an “Address” column, and a “PhoneNumber” column.
Create the rest of your columns: After finishing filling out the fields for the Primary Key. You will notice that new fields appear underneath it. These allow you to enter in your next column. Fill out the fields as you see fit. And ensure that you pick the right data type for the information that will be entered in that column.
Save table:When you are finished creating your columns, you will need to save the table before entering information. Click the Save icon in the toolbar, and then enter in a name for the table. Naming your table in a way that helps you recognize the contents is advisable, especially for larger databases with multiple tables.
Next step in How to create a sql database is to Add data to your table: Once you’ve saved your table, you can begin adding data to it. Expand the Tables folder in the Object Explorer window. If your new table is not listed, right-click on the Tables folder and select Refresh.
The center window will display fields for you to begin entering data. Your ID field will be filled automatically, so you can ignore it right now. Fill out the information for the rest of the fields. When you click on the next row, you will see the ID field in the first row fill automatically. Continue this process until you have entered all the information you need.
Execute the table to save the data: Click the Executive SQL button on toolbar when you have finished entering the information to save it table 12. Last step in How to create a sql database is to Query your data: At this point, your database has been created. You can create as many tables as u need within each database. you can now query your data for report or any other administrative purpose.
