The document discusses different database management systems like Microsoft SQL Server and MySQL. It covers how to create databases, tables, and queries in both SQL Server Management Studio and MySQL Query Browser. Examples are provided of creating databases and tables using SQL scripts as well as executing queries and viewing the results in the respective management tools.

2. Key Concepts DBMS variations SQL Server features Queries and types of queries SQL Server Management Studio MySQL features Scripts Queries Database creation

3. MSSQL Management Studio The Object Explorer shows SQL Server 2005 objects and the folders that are used to contain and organize those objects The Summary tabbed window displays the objects within the object selected in the Object Explorer window The System Databases folder contains database objects for the databases automatically created by SQL Server 2005 The Databases folder is selected in the Object Explorer window, so the Summary window shows the contents of Databases The Art_Course_Database datbase object holds the database named Art_Course_Database

4. Creating a database in MSSQL Click New Database to create a new database Right-click Databases to display the shortcut menu

7. Creating SQL Scripts This is the Microsoft Notepad text editor—the file name is DBC-e03-MSSQL-WPC-Create-Tables.sql The SQL keyword Name is enclosed in brackets as [Name] The lines that start with /* are comments—any text between the /* and the */ characters on a line is a comment and ignored by the DBMS when it runs the SQL

8. Queries and types of queries Query Definition: anytime we need to add, remove, update, or view information from a database, we issue a request; this is called a query in database terms The contents of the query depend on the type of query Types of queries SELECT Must specify what we want to view and which table we want to view from INSERT Must specify what we want to insert, and which table to place it in DELETE Must specify what we want to delete from which table

9. Queries and types of queries (cont'd) UPDATE You get the idea ... Other less often used types CREATE DB DROP DB ALTER TRUNCATE etc.

10. Executing SQL scripts You have to specify which database is being used when the script is run—select WPC from the drop down list before executing the script Click the Execute button in the SQL Editor toolbar to run the script The tabbed script window with the open script displayed—to close this window after the script is run click the X symbol to the right of this tab

11. Script results The objects representing the tables created by the script are shown in the expanded Tables folder— dbo stands for database owner Messages are shown here—either that the commands were successful or appropriate error messages

12. Query window Click the New Query button in the Standard toolbar to open the query window and display the MySQL Editor toolbar Select the database that you want to query by clicking the database name to select the database The selected (active) database name appears in the SQL Editor toolbar Type your SQL query into this tabbed window

13. Sample Query The tabbed Results window—you can adjust window boundaries and column widths using standard Windows drag-and-drop techniques The SQL query—the asterisk after .sql on the window tab means the text has been changed but not saved

14. MySQL Query Browser

15. MySQL Query Browser The SQL query text box in the MySQL Query Browser Query Toolbar —type SQL queries in this area The ResultSet window—the results of a query are displayed here The Schemata pane—the default schema can be selected from the available database schemas

16. Creating a database using MySQL Browser Right-click anywhere in the Schemata pane to display the shortcut menu

17. New schema dialog (Schema just means table and it's related layout and attributes) Click the OK button to create the new database Type the new database (“schema”) name here

18. This is the Microsoft Notepad text editor—the file name is DBC-e03-MySQL-WPC-Create-Tables.sql Creating an SQL script

19. 3NF Solution All the fields in the MEMBER table are determined by email . In VISIT, all non-key fields are determined by id and email . All the non-key fields are determined only by the primary key.

20. Opening script The Script 1 tabbed window with the open script displayed—to close this window after the script is run click the X symbol on this tab Click the Execute button to run the script After the script is run, expand the WPC schema object to see the tables created by the script

21. Query results This is the MySQL Query Browser Query Toolbar —enter your SQL statement into this text box and then click the Execute button to the right to run the query Query results are shown in the Resultset window—you can use standard Windows drag and drop techniques to change the column widths to adjust the results display

22. Additional Results Displays new set of data as a result of running the script Use the File | New Resultset Tab command to open an additional tabbed Results window—you can have multiple Results and Script windows open at the same time
