How does the computer create a data source?

Create a data source on your computer. If we want to create a database, we must determine the name, owner and size of the database, and the composition of the files that store the data. When creating a database, we feel that we have to pay the maximum amount of data. Because we want to create a data file as large as possible, when we start this object, we right-click the database node in Object Explorer, and then we can create it. So now let's explain.

Knowledge point ①: First, we need to start an object, then write again on the node that opens the database in the object explorer window, and then select the new database command from the shortcut menu.

Knowledge point 2: Step 2: When the dialog box of creating a new database pops up, we click the database name is insufficient in the general data page, and then enter the name of the database to be created. There are two names in this database file, logical file name and physical file name, so explain what the logical file name is. The logical file name is the name used when all statements refer to physical files. Logical file names must conform to the rules of this flag. Each database has only one logical file name, and the physical file name is the physical file containing the directory path. Some databases contain at least one main data file and one transaction file, and their storage paths and file names can be modified again. Of course, you can also use the Add button or add multiple files.

Knowledge point ③: Step 3: You can set the initial size of the file in the initial size of the data file of the regular data page. Click the button after the automatic growth mode to set the automatic growth mode and the maximum file size, and click the button after the path to set the storage path of the file.

Knowledge point ④: Step 4: Set the attribute options of the database on the options data page, add and delete file names on the file group data page, and expand the database in the object resource management window to see the newly created database.
