Final answer:
The correct answer is option D: Transition. Hierarchical, Network, and Relational are all types of databases, but Transition is not a type of database.
Step-by-step explanation:
The correct answer is option D: Transition.
Hierarchical, Network, and Relational are all types of databases, but Transition is not a type of database.
Hierarchical databases organize data in a tree-like structure, where each record has a parent-child relationship. Network databases use a more flexible structure, with records connected through pointers. Relational databases store data in tables, with relationships established through keys.
In the context of databases, a transition is not a type of database but rather a term that may be used in various contexts, such as in state transitions or transaction states within database management. When discussing types of databases, hierarchical, network, and relational databases are well-established categories. A hierarchical database organizes data into a tree-like structure, where each record has a single parent. Network databases allow each record to have multiple parent and child records, forming a graph structure. The most widely used type today, the relational database, organizes data into tables with rows and columns, where relationships between entities are defined through keys.
