Appendix D
Purpose

Purpose: to get an idea about the objective, structure, and sequence of DDL and DML commands of the SQL language using the example of creating a database "LIBRARY".

 

D.1. Script-file in the Interbase DBMS

A script file – is a source file that contains script in any scripting language. This is the most general definition of script file we could find. Let's narrow this definition for our case: a script file is a sequence of DDL and DML commands of the SQL language for creating a physical database model.

In our opinion, the technique of using SQL scripts in Interbase is not different from other DBMS for creating a physical database model. In general, for the Interbase DBMS, it includes three consecutive steps:

  1. Create a script file using a text editor.
  2. Execute the file using isql in IBConsole.
  3. View execution results and commit changes to the database.

The Notepad application will be enough for creating and editing a script file in Windows OS. Use MS Word for this with caution. This application has hidden control characters. They may be the cause of atypical behavior of the script-file handler in the Interbase DBMS.

Experience shows that the script for creating a physical model of a relational database in a script file is most convenient to perform step by step. After each SQL statement or group of statements, you can see the result of their work. If it suits you, copy the SQL statements to a script file. This approach will allow you to get the script for restoring the initial structure of the database. In the future, you can supplement or change it. It remains to add that a high-quality logical database model ensures the success of its physical modeling.

 

The "LIBRARY" DB creating

The script file . will be used for the database “LIBRARY” creating. It contains 8 parts:

  1. Creating domains.
  2. Creating tables.
  3. Creating data views.
  4. Creating primary key value generators.
  5. Defining exceptional situations.
  6. Creating triggers and stored procedures.
  7. Creating table indexes.
  8. Adding information to tables.

A « COMMIT;» operator terminates the script file. It closes a transaction that was automatically opened just before the start of execution. It fixes all the changes that have been installed in the database "LIBRARY". All other statements in script file have detailing comments.

Let's take a closer look at the sequence of actions for creating the "LIBRARY" database in the "Interbase" DBMS.

  1. Read the information about installation, registration, and licensing information about using "Interbase" DBMS.
  2. Install "Interbase" DBMS on your device.
  3. Open IBConsole.
  4. Choose Menu Bar item Database in the IBConsole interface.
  5. Select Database Menu’s item Create database….
  6. Point a place and DB name in the «Create Database» dialog window. For example, C:\DB\LIBRARY.IB.
  7. Don’t change other parameters and tap the button «OK».
  8. Enter the password «masterkey» and tap the button «Connect» in the «Database Connect» dialog window.
  9. Select the node LIBRARY.IB in the Server Tree in the IBConsole.
  10. Choose the button [Button appearance] Interactive SQL in the IBConsole Interface.
  11. Copy the script-file from appendix D.3 to the Input Aria of the Interactive SQL dialog window.
    1. Mark the /* CREATING DOMAINS. phrase. It is in the first row of the appendix D.3.
    2. Using scrolling, find the COMMIT; statement. It is in the last row of the appendix D.3.
    3. Holding Shift, click the mouse’s left button to the right of the COMMIT; statement.
    4. Use Ctrl+C to copy the selection to the clipboard.
    5. Go to Input Aria of the Interactive SQL dialog window and press Ctrl+V.
  12. Select the item Transactions in the Menu Bar of Interactive SQL dialog window.
  13. Use the Options item in the Transactions Menu
  14. Set the Write Access Mode (item 3, fig. 1) in the Transaction Editor dialog window and tap the «ОК button.
  15. Tap the button [Button appearance] Execute of Tool Bar in the Interactive SQL dialog window.

Fig. 1. The Transaction Editor dialog window

Fig. 1. The Transaction Editor dialog window

This script file was checked for errors in Interbase 2020. There are DDL and DML SQL commands in the script file. They will create all objects and add all data into DB LIBRARY.IB. For example, then you can see list of LIBRARY.IB tables and views in the Tables and Views left part of the Interactive SQL dialog window. Find the READERS table on this list. Tap it. You can see the columns list of this table. Compare it with READERS table description in the physical model.

You have a possible for data viewing in the READERS table. Run the simplest SQL from example 6.1. Just copy it into the Input Aria of the Interactive SQL dialog window. Then select button [Button appearance] Execute in the Tool Bar. Results will be displayed in the Output Aria.

Have enjoy learning about relational database organization.

Actually, these triggers replace the sentence PRIMARY KEY (Code) in the CREATE TABLE PasportData statement .

The triggers ensure the Passport entity integrity. First, they exclude adding two same values of primary key in Code field. Second, they prevent adding a couple of the same values in the Series and Number fields. These fields are a potential key of the PasportData table.

An exception is generated for both cases.

ATTENTION!!!

We can't use foreign keys in the Readers and Librarians tables after removing sentence PRIMARY KEY (Code) from the CREATE TABLE PasportData statement. We say about the sentences FOREIGN KEY (PasportCode) REFERENCES PasportData in the CREATE TABLE Readers and CREATE TABLE Librarians statements.

But the database needs this referential integrity for correct working with readers' and librarians' data. The support of this referential integrity is ensured by triggers and stored procedures. They are located and described below.

ATTENTION!!!

We can’t use triggers and keys for data integrity insuring between pair of relations at the same time. We have to begin with keys. This is the simplest way of data integrity enforcing. If you need more complex checking or actions, you will choose triggers.

CREATE PROCEDURE BfrInsUpdInReaders

/* The procedure is called from the BfrInsInReaders and BfrUpdtInReaders triggers. The BfrInsInReaders trigger is called before an INSERT statement. The BfrUpdtInReaders trigger is called before an UPDATE statement.

Actually, these triggers replace the sentence PRIMARY KEY (CODE) in the CREATE TABLE Readers statement.

Triggers ensure the integrity of the "reader" entity. They exclude adding same values of the potential keys in Code, PassportCode and ReaderCardNumber column for two different readers.

Adding the existing value for any potential key generates an exception.

ATTENTION!!!

We have deprecated the PRIMARY KEY (Code) sentence in the CREATE TABLE Readers statement. In this case, referential integrity between the Phones, BookGiveOutRecord tables and the Readers table should have been maintained using triggers. The Phones.ReaderCode, BookGiveOutRecord.ReaderCode foreign keys have been stayed the same.

ATTENTION!!!

We can’t use triggers and keys for data integrity insuring between pair of relations at the same time. We have to begin with keys. This is the simplest way of data integrity enforcing. If you need more complex checking or actions, you will choose triggers.

They exclude adding two identical phone numbers for one reader. It means that can’t two the same pairs of the ReaderCode and PhoneNumber values in the Phones table. This pair of columns is a composite potential and primary key of the Phones table.

Adding the existing pair of values for primary key generates an exception.

The BfrInsInPhones, BfrUpdInPhones and BfrDltInReaders triggers provide referential integrity between the entities "Reader's phone number" ( the Phones relation) and "Reader" ( the Readers relation). Additionally, the BfrInsInPhones and BfrUpdInPhones triggers provide referential integrity between the entities "Reader's phone number type" ( the Phones relation) and "phone type" ( the PhoneTypes relation).

This makes it possible not to define the FOREIGN KEY (ReaderCode) REFERENCES Readers and the FOREIGN KEY (PhoneTypesCode) REFERENCES PhoneTypes in the CREATE TABLE statement.

ATTENTION!!!

/* The COMMIT statement closes the transaction. All changes in Library database are committed. */

COMMIT;

 

Conclusions

1. The script-file structure has the big differences with the description sequence of the Library physical model. It relations with the convenience presentation of code sections. Each section includes statements for defining one-type objects. For example: domines, tables, views and other.

2. Creating indexes of tables didn’t reflect in the Library physical model because they use for shortening time for data select with SQL-queries.

3. Script-file is a transaction that needs to end by the COMMIT statement for fixing of all changing in Library database.
