CPSC 304, E/R diagrams and schemas
member from each project team must either submit the following by using
the handin directory "project-schema" (i.e., running the command
"handin cs304 project-schema", where all of your files are in a
directory called ~/cs304/project-schema") To do so, you'll need to get an account on the CS ugrad machines.
- A cover page
- An E/R diagram for the database the application will use. (I suggest using Microsoft Visio or the online Gliffy to
draw your ER diagram, but hand drawn diagrams are fine. You may hand
those in at the beginning of class if you don't want to scan them in.
However, make sure you retain a copy for yourself as we will not be
returning them). Your E/R diagram should include:
- At least 5 entity sets. For each entity set:
will likely be a numeric attribute. This suggestion is designed to help
with the discovery of the primary key. However, you may find that some
entities do not require it.
- Identify candidate keys, and the primary key. Each entity must have a primary key
least 5 relationships. For each relationship, identify the cardinality
constraint and other constraints, such as participation constraints.
- The schema derived by translating from your ER diagram (above). For each table:
- List the table definition e.g., Table1(attr1: domain1, attr2: domain2...)
- specify the primary key, foreign keys, and other constraints that the table has to maintain
all functional dependencies that are applicable to the table (including
the ones involving the primary key). For each functional dependency,
briefly describe its meaning in English.
- List all candidate keys
each of your tables, if necessary, to be in 3NF or BCNF. If you think
that a certain table is already in 3NF or BCNF, briefly explain why.
Give the list of tables,
their primary keys, and foreign keys after normalization.
- The SQL DDL to create all the tables in SQL. All primary keys and foreign keys must be declared appropriately.
- Populate each table with at least 5 tuples. Show the instance of each relation after inserting the tuples.
requirements stated herein, are not expected to be complete. As you
start analyzing these requirements you may notice that certain details
are missing. In this case, you may make any reasonable assumptions
about them, but if there is any uncertainty about some requirements you
should post an inquiry on the bulletin board. The TAs and the
instructor will try to respond to these requests as soon as possible.
