Understanding Database Models

What is the primary function of database management software (DBMS)?

• To develop web applications

• To analyze data trends

• To create and manage databases

• To design user interfaces

Which of the following is a characteristic of hierarchical and network database models?

• They use pointers to connect records

• They are the most modern database models

• They allow users to create their own searches

• They are primarily used for multimedia files

What was a major limitation of hierarchical and network database models?

• They relied on predicting user questions

• They could not store text data

• They were too complex to implement

• They were incompatible with legacy systems

How do relational databases differ from hierarchical and network models?

• They are only used for text-based data

• They require predefined pathways for queries

• They allow users to create their own searches

• They use pointers to connect records

What is a key feature of the relational database model?

• It allows for self-contained records

• It uses a hierarchical structure

• It is only suitable for legacy systems

• It requires manual indexing of data

What is an object in the context of object-oriented databases?

• A text-based data entry

• A logical grouping of related data

• A pointer to another record

• A predefined search query

Why did object-oriented models become important with the rise of the internet?

• They required less storage space

• They could handle multimedia files

• They were easier to implement

• They were compatible with all legacy systems

What is a benefit of object-relational models?

• They are only used for legacy systems

• They allow for the indexing of multimedia

• They eliminate the need for database management software

• They simplify text-based data management

Which database model is best suited for handling real-world objects?

• Hierarchical model

• Network model

• Relational model

• Object-oriented model
