A company needs a database in which a wide variety of data models, such as columnar and graph formats, can be used.

Object-oriented databases are structured to store data in the form of objects, similar to object-oriented programming. While they can manage complex data types, they are not specifically designed to handle a wide variety of models like columnar and graph formats. Their focus is primarily on encapsulating data and behavior, limiting their flexibility compared to NoSQL databases.

Cloud databases refer to databases that are hosted in a cloud computing environment, allowing for scalable and remote access. While cloud solutions can host various database types, the term itself does not specify the ability to accommodate multiple data models like NoSQL does. Thus, it does not inherently ensure the flexibility to manage both columnar and graph formats.

Distributed databases are systems that store data across multiple locations or nodes, enhancing availability and fault tolerance. However, being distributed does not imply support for diverse data models. A distributed database can still be relational or a single model type, lacking the inherent flexibility that characterizes NoSQL databases.
