  1. The project should include the following items • Graphical process model containing 3 to 10 activities/process steps. • An Entity/Object Pool with 3 to 5 entities. • An Entity Relationship Matrix for the entities identified in step 2. • A fully refined or attributed Logical Data Model normalized to third normal form. • A data dictionary for the logical model created in step 4. • An Access 2007 Database created by transforming the logical model in step 4 into a physical design. Each table in the database should contains at least 4 records. • At least two Forms for the database created in step 6. The forms at a minimum should enable record addition, deletion, modification. • At least two Queries for the database created in step 6. • At least two Reports for the database created in step 6.

  9. 6.0 An Access 2007 Database created by transforming the logical model in step 4 into a physical design • See Access File: Manage Video Rental v1.accdb

  10. First Normal Form - (1NF) • Every key and non-key attribute of an entity must be single valued • No entity instance can have multiple values for a given attribute • i.e., The No Repeat Rule • A violating entity is corrected by removing repeating or multivalued attributes to another, dependent (child) entity

  11. First Normal Form - Example RESTAURANT REST NAME ADDRESS PHONE # EMPLOYEE NAME REST NAME ADDRESS PHONE # EMPLOYEE NAME BURGER KING 123 NORTH ST 123-2345 JOHN, SUE, LISA TACO HOUSE 345 126TH PLACE 765-8907 MARY, BILL FISH COMPANY 77 SUNSET AVE 395-5682 ED, SAM, JOSE, RICK RESTAURANT EMPLOYEE REST NAME EMPLOYEE NAMEREST NAME ADDRESS employs PHONE # POSITION

  12. Second Normal Form - (2NF) • An entity that is in first normal form and each non-key attribute is dependent on the entire primary key • No non-key attribute instance can be determined by knowing just part of an entity instances key • A violating entity is corrected by removing to a parent entity any attributes that depend on only a subset of the primary key

  13. SUPPLIER RESTAURANT ORDER REST NAME SUPPLIER NAME ORDER ITEM PHONE # SUPPLIER NAME (FK1) Second Normal Form - Example RESTAURANT ORDER REST NAME SUPPLIER NAME ORDER ITEM SUPPLIER PHONE # REST NAME SUPPLIER NAME ORDER ITEM SUPPLIER PHONE # BURGER KING SAM'S PRODUCE BEEF 123-2345 TACO HOUSE SALSA INC. PEPPERS 765-8907 FISH COMPANY SAM'S PRODUCE SNAPPER 123-2345 fills

  14. Third Normal Form - (3NF) • An entity that is in second normal form and each non-key attribute is only dependent on the entire primary key and nothing other than the key • No non-key attribute instance can be determined by knowing the value of another non-key attribute for the same instance • A violating entity is corrected by removing to a parent entity any attributes exhibiting transitive dependencies (non-key attributes that not only depend on the whole key but also on other non-key attributes)

  15. Sample Information Model

  16. Categorization Example WESTERN SUSPENSE COMEDY MALE FEMALE (MOVIETYPE) (SEX) MOVIE PERSON INCOMPLETE CATEGORIZATION (there are other movie types such as Documentary) COMPLETE CATEGORIZATION

  17. Planning Model Example MOVIE CUSTOMER Is Rented By / Rents Is Produced In/ Produces (TYPE) STUDIO WESTERN

  19. Non-Specific ConnectionRelationships • A relationship where one instance of an entity may relate to 0, 1, M instances of a second entity; and one instance of the second entity may relate to 0, 1, M instances of the first entity • For Example: • A Customer Rents at 0,1,M Movies, and Each Movie is Rented by 0, 1, M Customers MOVIE CUSTOMER Movie Number Cust Number rents/is rented by Name Name Rating Address Rental Rate Status Code

  20. Specific Connection Relationships • A Parent - Child relationship that resolves a non-specific relationship to capture additional detail • A relationship where one instance of an entity (Parent) may relate to 0, 1, M instances of the second entity (Child), and the Child entity is related to one and only one instance of the Parent entity • For Example: • A CUSTOMER Rents a specific copy of a MOVIE Movie Rental Record Customer Movie Number Movie Copy Id Rental Date Cust Number (FK) Cust Number rents according to Name Address Status Code
