0000 T-Mobile 12:38 PM 1 92%-. Given the information below, create the fully labeled Crow's Foot ERD using a specialization hierarchy where appropriate (use Visio). The ERD must contain all primary keys, foreign keys, and main attributes. Business rules are defined as follows: At a hospital, each patient is classified as either a resident patient or an outpatient. All patients have common attributes ID, first and last name, and diagnosis and unique attributes that are specific to their groups. The list of such attributes includes but is not limited to the following: a summary of the treatment received in the hospital (resident patients) and the check back date (outpatients) In addition, resident patients are classified as patients who need a routine checkup, patients who need a surgery, and patients who need both a checkup and a surgery. Each group is characterized by unique attributes (for instance, a surgery date, etc.). Each patient creates a record in the HOURS table that keeps track of the total number of hours a patient spent in the hospital. The table also includes the COMMENT" field where any additional information may be recorded. One record is related to one patient only.Explanation / Answer
A database model is a type of data model that determines the logical structure of a database and fundamentally determines in which manner data can be stored, organized, and manipulated. The most popular example of a database model is the relational model, which uses a table-based format.
An HierarchicalDatabase is an implementation of storage that can be described using the CompositePattern. Composites are ubiquitous in software engineering. Composites are common, easy to model, offer easy control of ownership. When a hierarchy works, no reason to get any fancier. But InterestingProblems usually require a data model that need more than a tree.
