Final answer:
option a,The type of database table that requires each column to have a unique attribute name is a relational database. This allows for clear identification and manipulation of data within the database.
Step-by-step explanation:
In the context of database systems, different types of databases have varying requirements for the structure of their tables and the uniqueness of column names. The question pertains to determining which kind of database table requires that each column has a unique attribute name. The correct answer is a) Relational database.
In a relational database, each table is structured with columns and rows, where each column must have a unique name. This requirement allows for the proper identification of each column in SQL queries and ensures that there is no ambiguity when accessing or manipulating data. NoSQL databases can have more flexible schemas and do not necessarily require column names to be unique across the database. Hierarchical and object-oriented databases use different paradigms for data organization that do not align with the typical table-column structure of relational databases.
