-- Table structure for table `claim`](https://image.slidesharecdn.com/task01arelationalschemacustomercustomeridcu-220929143723-3b9ad6b2/85/TASK-01-a-RELATIONAL-SCHEMA-Customer-CustomerID-Cu-11-320.jpg)
TASK 01 (a) RELATIONAL SCHEMA Customer (CustomerID, Cu
- 1. TASK 01 (a) RELATIONAL SCHEMA Customer ( CustomerID , CustomerName, CustomerAddress, CustomerContactNum) Parcel ( ParcelID , ParcelWeightInGrams, FromAddress, ToAddress, DateCollected, ParselValue, Charges, Status) Delivered (DeliverdDate) Returned (ReturnedDate) Lost (LostEntryDate) Invoice ( InvoiceID, InvoiceDate, InvoiceAmount) Claim ( ClaimID , ClaimLodgedDate, ClaimSettledAmount, ClaimPaidDate) Employee ( EmployeeID , EmployeeName, EmployeeStartDate) On the basis of relationship that exist between the entities, the table can be further broken down as;
- 2. Since one customer can order for multiple parcels therefore, 1 to many relationship exists between them. · Parcel ( ParcelID , ParcelWeightInGrams, FromAddress, ToAddress, DateCollected, ParselValue, Charges, Status, CustomerID ) Foreign Key: CustomerID Since there is 1 to1 relationship between Parcel and Delivered, Parcel and Returned, Parcel and Lost. · Delivered (ParcelID,DeliverdDate) Primary Key: ParcelID · Returned (ParcelID,ReturnedDate) Primary Key: ParcelID · Lost (ParcelID,LostEntryDate) Primary Key: ParcelID Since 1 to 1 relation exists between Parcel and Claim. · Claim ( ClaimID , ClaimLodgedDate, ClaimSettledAmount, ClaimPaidDate, ParcelID ) Foreign Key: parcelID Since 1 to 1 relation exists between LostParcel and Claim. · Lost ( LostId ,LostEntryDate,
- 3. ParcelID ) Primary Key: LostID Foreign Key : ParcelID Since there is 1 to 1 relationship between Parcel and Invoice 1. Invoice ( InvoiceID, InvoiceDate, InvoiceAmount, ParcelID ) Foreign Key: parcelID Since there is 1 employee can be responsible for multiple Parcel. Therefore, 2. Parcel ( ParcelID , ParcelWeightInGrams, FromAddress, ToAddress, DateCollected, ParselValue, Charges, Status, CustomerID, EmployeeID ) Foreign Key: CustomerID,EmployeeID Since 1 to many relationship exists between Employee and
- 4. · Delivered ( DeliveredID , ParcelID,DeliverdDate, EmployeeID ) Primary Key: DeliveredID · Returned ( ReturnedID , ParcelID,ReturnedDate, EmployeeID ) Primary Key: ReturnedID · Lost ( LostId ,ParcelID,LostEntryDate, EmployeeID ) Primary Key: LostId Foreign key: EmployeeID,ParcelID TASK 01 (b) NORMALIZATION 1. Parcel ( ParcelID , ParcelWeightInGrams, FromAddress, ToAddress, DateCollected, ParselValue, Charges, Status, CustomerID, EmployeeID ) In this one customer can order multiple parcels, therefore customerID is not enough to uniquely identify a tuple. There is
- 5. no partial key dependency. The primary key is the only key that identifies the tuple, therefore, this table is 2NF. For 3NF, there must be a transitive dependency, but in this table here is no attribute that can further identify a tuple uniquely, therefor it is already in 3NF 2. Delivered ( DeliveredID , ParcelID,DeliverdDate, EmployeeID ) In this table, there is no partial key dependency, therefore it is already in 2NF. Every attribute is fully dependent on DeliveredID, there is no transitive dependency among the attributes because no one attribute can uniquely identify any other attribute. Therefore, we say it is already in 3NF TASK 02 INTEGRITY CONSTRAINTS Attribute Data type Integrity constraint implemented
- 6. Error message DeliveredID Autonumber Primary Key NULL DeliverdDate Date/Time EmployeeID Number Foreign Key -Indexed
- 7. ParcelID Number Foreign Key -Indexed Attribute Data type Integrity constraint implemented Error message ParcelID Autonumber Primary Key
- 8. ParcelWeightInGrams Number Decimal upto 2 places FromAddress LongText ToAddress LongText DateCollected Date/Time
- 9. Status Shortext In LOOKUP, Display Control=List Box Row source Type= Value Type RowSource = "Collected";"Transit";"Delivered";"Returned";"Lost" EmployeeID,CustomerID Number Charges Number
- 10. TASK 03IMPLEMENTATION REPORT 1. Any two interesting things/procedures you have learnt by doing this assignment. How to add dropdown menu in status was one interesting thing to learn about. While creating relationship, how to link the primary and foreign key with each other. 2. Any one of the assignment tasks that was relatively difficult / complex to solve but has been successfully completed by you. Running queries were the most difficult work. -- phpMyAdmin SQL Dump -- version 3.3.9 -- http://www.phpmyadmin.net -- -- Host: localhost -- Generation Time: May 24, 2019 at 11:53 AM -- Server version: 5.5.8
