68. A company needs a database in which data is stored in a plain text document and is separated by delimiters, such as commas. Which type of database is needed?
Answer: C
A flat-file database is needed.
A flat-file database is suitable for storing data in a plain text document where data fields are separated by delimiters like commas. This structure allows for simple data management without the complexities of relational databases.
A) Hierarchical
A hierarchical database organizes data in a tree-like structure, where each record has a single parent and potentially many children. This model is not appropriate for plain text storage with delimiters, as it relies on relationships rather than flat data representation.
B) Distributed
A distributed database spreads data across multiple locations or nodes, allowing for scalability and redundancy. However, it does not inherently support the plain text format with delimiter-separated values, making it unsuitable for the requirements specified.
C) Flat-file
A flat-file database is specifically designed for storing data in a single file format, using delimiters to separate fields. This type of database meets the company's need for a simple text-based solution, making it the correct choice.
D) Cloud
A cloud database refers to a database that is hosted on cloud computing platforms, providing scalable storage and access. While it may offer various database types, it does not specifically address the requirement for a plain text format with delimiters, hence is not the appropriate choice for this scenario.
Conclusion
The flat-file database is definitively the correct answer as it directly aligns with the requirement of storing data in a plain text format with delimiters. Other options either involve complex structures or do not fulfill the specific need for a simple, text-based data storage solution.
