1. Partition the sentences Partition the sentences (database requirement description in natural language) into homogeneous groups

DEPARTMENT The company is organized into many departments. Each NAME department has a name, a number, and an employee who manages NUMBER the department. We keep track of the start date when that MANAGER employee started managing the department MGR-START-DT

DEPT-LOC DEPT-NUM A department may have several locations. LOCATION

EMPLOYEE NAME SSN ADDRESS We store each employee’s name, social security number, address, SALARY salary, sex, and birth date. Employees are classified into managers, SEX technicians, engineers, or secretaries based on job types, and can also BIRTHDATE classified into salary-employee or hourly-employee. JOB-TYPE SAL-HOUR DEPT-NUM

HOURS An employee is assigned to one department but may work on EMP-SSN several projects, which are not necessarily controlled by the same PROJECT department. We keep track of the number of hours per week that an WEEK-HOURS employee works on each project.

PROJECT Each project may be worked by several employee workers. Some NAME employee may manage several projects, but only one manager for each MANAGER project. DCIS850-doylet Page 4

EMPLOYEE NAME SSN ADDRESS SALARY SEX We also keep track of the direct supervisor of each employee. BIRTHDATE JOB-TYPE SAL-HOUR DEPT-NUM SUPERVISOR

PART NUMBER Each project uses a certain number of parts supplied by suppliers. DESCRIPTION

SUPPLY Each part may be supplied by different suppliers (different suppliers PART may supply the same parts) and each supplier supplies different parts. SUPPLIER

SUPPLIER NUMBER We keep track of each supplier with supplier number, supplier name, NAME status (rating or status value), and city (location). Each supplier is STATUS located in exactly one city. CITY

PART NUMBER Parts are also kept track of with part number, part name, color, NAME weight and city (location) where the parts of that type are stored COLOR (only one location). Each part may consist of several other parts WEIGHT (subparts), each part may be used by several other parts as subparts. CITY SUBPART-OF

DEPENDENT ESSN We want to keep track of the dependents of each employee for NAME insurance purposes. We keep each dependent’s name, sex, birth SEX date, and relationship to the employee. BIRTHDATE RELATIONSHIP DCIS850-doylet Page 5

telephone numbers are stored as free-flow text. DCIS850-doylet Page 7

2. Design the conceptual schema

Design the conceptual schema of the company database by using ER diagram and CSDL (Conceptual Schema Definition Language). Your conceptual design of the database should include the following but not limited to:

a. Entities b. Subclasses and Superclasses c. Relationships d. Keys e. Structural constraints (Cardinality ratio and participation constraints)

3. Relational database schema Transform the ER schema of database you get from step 2 into the corresponding relational database schema

a. Specify all the key attributes of relations and any referential integrity constraints. b. Specify the data item format for each attribute in each relation schema. c. Specify all the functional dependencies you could infer from the requirements.

5. Normalize relation schema Normalize relation schema in the database design that you get from step 4 into either 3NF of BCNF if it is necessary. Taking each Functional Dependency (FD) from the Universal Relation shown under question 1. Partition the sentences, the normalization is reasoned as follows…

FD1 FD2 DEPARTMENT is in non-first normal form DEPARTMENT_NAME (non-1NF) because DEPT_LOCATION(S) is not

DEPARTMENT_NUMBER an atomic value. After normalization, two tables are generated in 1NF, DEPARTMENT and DEPARTMENT_MANAGER LOCATION, which are in 2NF because all non- DEPT_MGR_START_DATE prime attributes are fully functional dependent on DEPT_LOCATION(S) the primary key.

DEPARTMENT LOCATION Both tables are in 3NF because DEPARTMENT_NAME DEPARTMENT_NUMBER there are no transitive or partial

DEPARTMENT_NUMBER DEPT_LOCATION dependencies, and in BCNF because there are no trivial DEPARTMENT_MANAGER dependencies included. DEPT_MGR_START_DATE

FD3 FD8 Employee details are in non-1NF because each DEPARTMENT_NUMBER employee may have more than one address or EMPLOYEE_NAME_FIRST phone number, so after leaving only atomic fields, the remaining EMPLOYEE fields are EMPLOYEE_NAME_MI already in 3NF without any transitive or partial EMPLOYEE_NAME_MAIDEN dependency, and BCNF without trivial EMPLOYEE_NAME_LAST dependencies.

EMPLOYEE_SSN Since FD8 requires tracking of the Supervisor of EMPLOYEE_SALARY each Employee, the field is added to produce the EMPLOYEE_SEX table shown below.

EMPLOYEE_BIRTHDATE From the employee fields, three separate tables, EMPLOYEE_JOB_TYPE ADDRESS, TELEPHONE and EMPLOYEE are EMP_SALARY_OR_HOURLY extracted; a field to identify the type of

EMPLOYEE_ADDR_LINE1 telephone is added. Like EMPLOYEE, ADDRESS and TELEPHONE are single key EMPLOYEE_ADDR_LINE2 tables in 2NF; without transitive or partial EMPLOYEE_ADDR_CITY dependencies they are in 3NF; and without EMPLOYEE_ADDR_ZIP trivial dependencies, both tables are in BCNF.

FD7 FD4 FD5 FD6 Combining FD4, FD5, FD6 and FD7, DEPARTMENT_NUMBER two tables are extracted, PROJECT and WORKS_ON. EMPLOYEE_SSN To avoid data entry errors, a ‘Project PROJECT_NAME Number’ attribute complements each

EMP_PROJ_HOURS/WEEK similar ‘Project Name’, which is used to build the join table required to log the PROJECT_MANAGER hours per week each Employee may work on separate Projects.

PROJECT WORKS_ON In both tables, all non-prime PROJECT_NUMBER EMPLOYEE_SSN attributes are fully functional

PROJECT_NAME PROJECT_NUMBER dependent on their primary keys, and without transitive, PROJECT_MANAGER EMP_PROJ_HOURS/WEEK partial or trivial PROJECT_DEPT_NUM dependencies, both tables are in BCNF.

FD10 PART_SUPPLIER Postponing FD9 to build its related tables, all the Supplier details in FD10 produce a table in BCNF. SUPPLIER_NUMBER SUPPLIER_NAME SUPPLIER SUPPLIER_STATUS SUPPLIER_NUMBER

SUPPLIER_CITY SUPPLIER_NAME SUPPLIER_STATUS

SUPPLIER_CITY DCIS850-doylet Page 13

FD11 Likewise, most of the Part details produce the table PART_NUMBER PART in BCNF.

PART_NAME On the other hand, since any part could be a subpart of PART_COLOR many parts and also could have many subparts, the PART_WEIGHT SUBPART_OF join table needs to be created. With PART_CITY only two fields depending on each other, this table is also in BCNF. PART_SUBPART_OF

PART SUBPART_OF PART_NUMBER PART_NUMBER

PART_NAME PART_SUBPART_OF

PART_COLOR

PART_WEIGHT

PART_CITY

PART_DESCRIPTION

FD9 After the Project and Supplier and Part tables have been PROJECT_NAME identified, their relationships specified by FD9 PART_NUMBER determine the creation of two tables. Both are join tables needed by their many-to-many relationships. PART_SUPPLIER

USES SUPPLIED BY An additional field is added to PROJECT_NUMBER PART_NUMBER keep track of the Quantity of parts

PART_NUMBER SUPPLIER_NUMBER supplied by each Supplier. Both tables are in BCNF. QUANTITY

FD12 The attributes remaining from the Universal Relation are EMPLOYEE_SSN part of FD12, which produce a DEPENDENT table. EMP_DEPENDENT_NAME Since the same Employee may have more than one dependent with the same name or birthday, all these EMP_DEPENDENT_SEX fields form the composite primary key. With all non- EMP_DEPEND_BIRTHDATE prime attributes fully functional dependent on their EMP_DEPEND_RELATION composite primary key, and without transitive, partial or trivial dependencies, this table is in BCNF.

8. Write a detailed report Write a detailed report of the database design and implementation.

Translating the requirements from free-flow text into possible relations was

helpful to define the fields or attributes needed by the database, in an universal

relation. Mapping the fields and their relationships on the universal relation, provides

a better understanding of the big picture, to extract its graphical representation or

Entity Relationship (ER) Diagram with attributes forming relations and their

relationships.

Once the ER Diagram was in place and compared with the original

requirements, many more details could be graphically included, like levels of

participation, subclasses, the degree of each relationship, cardinality ratios,

multivalue attributes, key attributes, and weak entities. After the ER Diagram was

considered complete, its plain-text conceptual schema was conceived, including the

data type and reasonable size of each attribute.

Continuously comparing with the original requirements, for consistency, the

conceptual schema was decomposed into the relational database schema, and the list

of all the join paths. Each join path defines the relationship between a foreign key and

a primary key, as shown on the relational database schema.

Normalization was reasoned from the universal relation, to make sure the

relationships on the extracted tables where at least in 3NF. It was during this process

that most unspecified requirements and their appropriate assumptions were included

for completeness, producing changes to the ER Diagram and its derivatives. It was

during normalization that I realized the need to have a separate Address table, and

that the Employee's name components did not need to be in a separate table. DCIS850-doylet Page 57

Implementing the database became a challenge, because the creation of tables had to follow a specific sequence to guarantee the availability of their pre- requirements. In the case of the recursively related tables like Department and

Employee, the first table was created without the foreign key pointing to the inexistent table, and that key added after that second table was created. A similar challenge was to sequence the dropping of the tables, and breaking the recursive relationship, to automate the deletion of the whole database and try the implementation again.

A spreadsheet and a formula for each table was required to automate the loading of all the tables, with enough details to run the final test queries. As each test query was built, new tuples were added to obtain satisfactory results. The final implementation of practice queries was also helpful to define additional assumptions, and to show the possibility of improving the database, with new concerns like the suppressing of leading zeroes on social security numbers.
