Tables
Tables are the fundamental units of storage within the database. Each table represents a specific entity, such as patients, providers, appointments, or billing records. In the diagram, tables are typically depicted as rectangular blocks containing fields (columns).
Fields/Columns
Fields define the data stored within each table. Each field has a data type (e.g., string, integer, date) and may have additional attributes like size, default values, or nullability.
Primary Keys
A primary key uniquely identifies each record within a table. For example, a patient ID or appointment number serves as a primary key. The diagram highlights primary keys to illustrate data uniqueness and relationships.
Foreign Keys
Foreign keys establish relationships between tables by referencing primary keys in other tables. They are crucial for maintaining referential integrity. For instance, an Appointment table may have a foreign key referencing the Patient table.
Relationships
Relationships depict how tables connect, such as one-to-many or many-to-many associations. These are often shown as lines or arrows between tables, indicating dependency or linkage.
Constraints and Indexes
Constraints enforce rules on data, such as unique values or not-null conditions. Indexes improve query performance and are often associated with specific fields.
Interpreting a Meditech Database Diagram
