1. Problem Statement:
K&L Sims Development, Inc. is a fast growing development
company based here in Rolla, MO. As a company grows, their need for
organization within the company begins to play a major role in whether or
not they are going to continue to grow and succeed. As this development
company grows, they must keep everything well organized in order to
make sure they continue to please everyone associated with the company.
The easiest way to organize a company’s information is by utilizing a
computer to do all of the hard work. Our intent is to help make the
following portions of K&L Sims Development, Inc. completely paperless.
The database we will design will help keep K&L Sims
Development, Inc. organized as it grows. The database will assist the
company by keeping track of the following items:





Who their suppliers are, what the company’s account
number is with each supplier, and each suppliers phone
number and address.
What houses are currently in the building process and the
key information for each house.
What lots/building sites they currently own.
The homeowners that they have sold to and key
information about each homeowner.
Who are their available contractors that they can contact to
perform specific jobs.
2. System Requirements:
What it does do:
This database system will allow K&L Sims Development, Inc. to
input all of their current information that they have collaborated over time
into the above listed categories (entities) in the database. Currently, all of
this information that will be entered into the database is handwritten.
Once the current information is entered, they will be able to quickly access
all of this information in the database, instead of searching through paper
files. They will also be able to add new suppliers, new houses that they
intend/are building, new lots/building sites they have purchased, new
homeowners that decide to buy from them, and any new contractors they
want to add to their list. The ability to efficiently update each file will also
be available through the database.
The user of the database will be the construction manager, who is
also the office/business manager. This individual will also be able to print
out reports on any of the information that is in the database, such as a list
of all the suppliers and the account number associated with each supplier.
What it doesn’t do:
This database system will not keep track of any financial
information for K&L Sims Development, Inc. This would involve a
whole new accounting aspect of the company. It will also not include the
advertisement portion of the company, or any realtor contacts or
information.

This will create a
new supplier entity
and insert each
input
into
the
correct attributes.
This will create a
new house entity
and insert each
input
into
the
correct attributes.
This will create a
new lot entity and
insert each input
into the correct
attributes.
This will create a
new
homeowner
entity and insert
each input into the
correct attributes.
This will create a
new
contractor
entity and insert
each input into the
correct attributes.
Update
Attributes
Any attribute in the
database will be able to
be updated. The user
will find the attribute
they wish to change and
make the change, then
click on an update button
on the interface.
When the update button is clicked
on, a success statement will appear
to let the user know that the system
has successfully updated the
attribute.
This will modify
the correct entity
based on which
attribute the user is
changing in the
system.
5. Estimate of Effort:
This is an estimate in total hours for each phase of the project:




Phase 1: 15 hours (collection of data, requirements, and
documentation)
Phase 2: 100 hours
Phase 3: 155 hours
Total: 270 hours
The hours that it will take to implement this database during the next
two phases are largely dependent on how well our group can learn to use
SQL and Oracle. Our group has no experience in either of these tools.
