Question
Select incorrect Data Models.
- Flat data Model
- Hierarchical Model
- Sequential Model
- Relational Model
Solution
Break Down the Problem
- Identify the listed data models.
- Determine the characteristics of each data model.
- Assess which of the listed models does not fit the standard data model classifications.
Relevant Concepts
- Flat Data Model: Represents data in a single, two-dimensional table without any relationships.
- Hierarchical Model: Organizes data in a tree-like structure with parent-child relationships.
- Sequential Model: Data organization based on sequences; often used in programming, not a traditional data model.
- Relational Model: Organizes data into tables (relations) that can be linked together.
Analysis and Detail
- The Flat Data Model, Hierarchical Model, and Relational Model are well-recognized types of database models.
- The Sequential Model, while it describes a method of data organization, does not commonly classify as a standalone data model in database design.
Verify and Summarize
Upon verifying the definitions and classifications of these models, it is clear that the Sequential Model is the odd one out.
Final Answer
The incorrect data model from the list is the Sequential Model.
