Database models define the relationship between different data elements, dictate how data can be accessed and define acceptable operations, the type of integrity offered, and how the data is organized. What type of database combines records and fields in a logical tree structure?
  1. Hierarchical Data Model
  2. Relational Database Model
  3. Network Database Model
  4. Object-oriented Database
Explanation
Answer: A - The hierarchical data model combines records and fields in a logical tree structure. The structure and relationship between the data elements are different from those in a relational database. These databases have well-defined, pre-specified access paths, but are not as flexible in creating relationships between data elements as a relational database; hierarchical databases are useful for mapping one-to-many relationships. The hierarchical structured database is one of the first types of database models created, but is not as common as relational databases.
