4 1. INTRODUCTION 1.1 Overview A company called Myson Pollock Fabrications have requested a Database system to manage their company s information. Myson Pollock produce Fabrications consisting of Pipes and Flanges for the chemicals industry and mainly deal with Oil Companies. In association with these Fabrications there must be regular testing of Fabrications and records of all staff, designs, materials and welding used in the production must be kept and be traceable. The Database must also hold details of suppliers of the Materials and any Purchase Orders related to them. Customer and contract details must also be stored. 1.2 Identified Constraints Due to the nature of what will need to be store and retrieved, there are several constraints placed on the database system. Because of Safety regulations imposed on the company the system must record data so that everything produced must have all aspects of its production and testing traceable. Constraints imposed are: In production a Pipe and Flange batch must come from a single batch of material. Also welding rods used on a batch must come from the same material batch. In production a Weld must be done by a member of Staff who has a current certificate for that type of weld. In production a Fabricator works with a single rig and its number and location is to be recorded with the member of staff In Testing and Quality Assurance a Tester must have details recorded for Last Sight Test and number of X ray tests carried out over last 12 months. 1.3 Deliverables Through the creation of the required system I hope to improve my knowledge of SQL and be able to produce a working model. On completion of this project I hope to have achieved the following: A full ERD of the proposed Database System. Create and populate all tables with some sample data 5

5 Create and test SQL Code for Queries and commands. Due to the size of the system and time constraints I will develop all the Tables and populate with sample code but will only give some DDL and DML examples. 6

6 2. ENTITY RELATIONSHIP DIAGRAM Below is the proposed Database System for Myson Pollock Fabrications. The structure and the Contents of the Tables have been derived from the case study requirements. With some of the Tables the Additional Support Material was used to help construct them. 7

7 3. TABLES Each of the following tables has been created from the information given on the Case Study. I have also added where I deemed necessary extra columns to enable better functionality and Data Integrity. Overall I have created 25 Tables to obtain the required system. The Screenshots below will show the design of each table, Primary / Foreign keys used and the table with sample data inserted. 3.1 Contract Table This Table will store all Contract information and be the creation point for any Unit orders. All Columns must be completed (No NULLS allowed) Primary Key: Foreign Keys: ContractID CustID 3.2 Customer Table Any customers who place a contract are added to this table. All columns must be completed. 8

8 Primary Key: CustID Foreign Keys: 3.3 Employee Table All employee data is to be entered on this table. Only job specific data may be stored on other tables. Some data can be omitted on this table. Primary Key: EmpID Foreign Keys: 3.4 Fabrication Table This table stores data regarding the Fabrications Identification number and the associated fabricator and order number for tracking purposes. 9

9 Primary Key: Foreign Keys: FabID EmpID, OrderID 3.5 Fabricator Table Stores information about an employee who is a fabricator. This is also used to help track production and also manage work load. Primary Key: EmpID Foreign Keys: 3.6 Flange Batch Table This table stores data on the production and composition of each flange supplied to the company. 10

10 Primary Key: Foreign Keys: F Batch Flange Type, Unit, Material Batch 3.7 Flange Type Table This table stores all the flanged used in any fabrication. Details about the flange must also be added. Primary Key: Flange Type Foreign Keys: 11

11 3.8 Flange Unit Table This tables stores information about any flange unit including technical information. Primary Key: Foreign Keys: Unit Material 3.9 Material Table Stores information on any material used within the manufacturing process. Primary Key: Material 12

12 Foreign Keys: 3.10 Material Batch Table This table store the batch information for any material that enters the factory. This is used for tracking purposes. Primary Key: Foreign Keys: Material Batch Material 3.11 Observation Table Table used to store testing information. 13

13 Primary Key: W Test Foreign Keys: 3.12 Pipe Batch Table This table stores data on the production and composition of each flange supplied to the company. Primary Key: Foreign Keys: P Batch P Type, Material Batch 3.13 Pipe Length Table Table stores technical information on the pipes supplied. 14

14 Primary Key: Length Serial Foreign Keys: P Batch 3.14 Pipe Type Table Stores information used in the different pipe types used in the fabrication. Primary Key: Foreign Keys: P Type Material 3.15 Rod Batch Table Stores information on the welding rod batched used. 15

15 Primary Key: Foreign Keys: R Batch Rod Type 3.16 Rod Type Table Stores information on the welding rods used to enable matching them to the correct welds. Primary Key: Foreign Keys: Rod Type Material 3.17 Test Operative Table Stores information on employees who are test operatives. 16

16 Primary Key: EmpID Foreign Keys: 3.18 Ultrasound Table Records testing information. Primary Key: W Test Foreign Keys: 3.19 Unit Order Table Stores information generated from contracts. This also includes a drawing reference number for tracking purposes. 17

17 Primary Key: Foreign Keys: OrderID ContractID, P Type, Flange Type 3.20 Weld Table Stores information on the welds used in a fabrication. Primary Key: Foreign Keys: Weld FabID, EmpID, Weld Type, R Batch 18

18 3.21 Weld Cert Table Stores information about the welding certificates required by welders. Primary Key: CertID Foreign Keys: 3.22 Welder Table Stores information on employees who are welders. 19

19 Primary Key: Foreign Keys: EmpID CertID 3.23 Weld Test Table Stores information on the testing of welds. Primary Key: Foreign Keys: W Test Weld, EmpID, FabID 20

20 3.24 Weld Type Table Stores information on the types if weld and the certificates associated with them. Primary Key: Foreign Keys: Weld Type CertID 3.25 X Ray Table Stores information on X Ray testing. 21

21 Primary Key: W Test Foreign Keys: 22

22 4. SQL CODE The section demonstrates manipulation of the database and its contents using SQL Code. Each individual section will show examples of Data Definition Language (DDL) and Data Manipulation Language (DML). The sample code used can be manipulated to be used with any Table in the Database by changing the Parameters defined in the sample code. 4.1 The SELECT Command (DML) The SELECT Command enables you to view specific information within a table. In this example I have chosen to view the Number of fabrications of 20 or above within the Contract Table. Note the Code used at the top of the screenshot and the results below it. 23

23 4.2 Adding a Record to a Table (DML) This section shows how to add a record to an existing table using SQL Code. In this example a 4 th record has been added to the Customer Table. Before: Table view showing only 3 records Code: View showing Code After: View showing new record. 24

24 4.3 Deleting a Record in a Table (DML) Using the previous example, we will now remove the 4 th record of the Customer Table. Below is the before and after views for Deleting a record. Before: The table showing 4 records Code: Shows the SQL Code to Delete a record After: The 4 th record is now removed 25

25 4.4 Updating a Record (DML) This section shows you how to update/change the contents of a given field within a record. Before: The code we will use is at the top of the window and the value we will update is located in record 2 under Number of fabrications. We will change this value from 30 to 50. Error: This error was produced due to the usage of within the Column Name. Corrected Code: You can see the has been removed from the Column name and the code has executed correctly. 26

26 After: you can now see the value has been change from 30 to

27 4.5 Ordering the records within a table (DML) Using the previous example, we can now order the records to show the information in a different way. In this example we want to order by the Number of fabrication and we want to see it in Descending order so we know who wants the most work. Note: the command DESC refers to Descending. Use the ASC command to order in Ascending order. Before: Shows the table before ordering After: Shows the code used at the top and the table in Descending order. 28

28 4.6 Creating a Table (DDL) This section shows how to create an additional table and also how to define a Primary Key. Also defined is the Data Types and if the fields will allow NULL s. Code: The screenshot below shows the code used to create a table. In this case a Supplier table. After: after refreshing the database structure you can now see the Supplier Table and also its structure view ready to receive data. 29

29 4.7 Dropping a Table (DDL) To remove or Drop a table from the database we can use the DROP TABLE command. Using the previous example we can drop the supplier table from the database. Code: You can see the code used and that it has ran successfully. I will not disappear from the view until you have refreshed the database tree structure. After a refresh: You can see it has now been removed. 30

30 4.8 Creating Views (DDL) This section describes the code used to create Views or Virtual tables. This views are stored within the tree structure and can be called upon within the SELECT Command used earlier in this document Code: The screenshot below shows the code used to create the view. Note the name for the view within the first line of code (in Black). Also note the view in the database tree structure. View: as you can see the view created only shows a small amount of data. This is because we only defined a small amount of data to be viewed (only ContractID s that have Number of fabrications of above 20) On the next page you can see the whole table for the Contracts and as you can see the ContractID has a Value for the Number of Fabrications of 50 and is the only one with a value above 20. Therefore the Code has executed correctly. 31

32 5. DETACH AND ATTACHING A DATABASE To be able to transport a database from one physical location to another or to add from a test environment to a live environment you can do the following. Note: The database created for this project has been detached from my Work PC and added to my user space at Teesside University (f ). 5.1 Detaching a Database To detach a Database, right click on the Database and select Tasks > Detach Then click Ok to detach the database 33

33 5.2 Attaching a Database To Attach or Reattach the Database, right click on Databases and click Attach. Click on Add on the next window and select the Database form the tree view (Location) and click OK To Transport the database to another location you can copy it from its existing location. 34

34 6. CRITICAL REVIEW 6.1 Review of Report I believe that this report conforms to the SCM Guidelines. However I do believe is could have added more relevant content to report to explain areas more clearly. 6.2 Review of Introduction I believe the key points were coved in the introduction and all key areas highlighted. 6.3 Review of ERD The production of the paper based model did give me some ideal of how the database would hang together. I only really developed the model once I used SQL Studio to design the database. I feel this section is a complete as it should be although extra notes on the ERD may be required. One oversight with the ERD and which was not mentioned in the Case Study would be adding in Supplier table to the database. I use the lack of this table to demonstrate code later in the report. 6.4 Review of Database implementation This was trickier than I first thought. As I am new to SQL design and implementation I feel that I took longer that planned to create relationships and also to ensure it flowed as required. Also imputing the sample data in the correct order to ensure database integrity (Some sections would not work due to relationships between tables. I.e can t enter data because it is not on another table first). This reassured me that the database is working as it should. 6.5 Review of SQL Code This was daunting challenge at first. The code I used was what I believed the company may want to use. After working with the code for a few minutes I felt more confident with it. 6.6 Review of Personal Development Overall I feel that my knowledge of SQL databases has been enhanced dramatically though the module. I work with SQL but up until now only through installing it and recovering data from backups. This module has given me a platform to develop further within my current career. 35
