How can properties in the database be defined?

Properties in a database are essentially defined as attributes that are associated with the data stored within it. These properties correspond to the columns in a database table. Each column represents a specific attribute or type of data that can be stored for every entry (or row) in that table. For instance, if you have a table for 'Products,' the columns might include properties like 'Product ID,' 'Name,' 'Price,' and 'Quantity.'

When we refer to properties as columns, it is important to understand that each property holds a specific piece of information that contributes to the overall structure of the database. This organization allows for efficient data management and retrieval, ensuring that users can access detailed information about each record in an orderly manner.

The other options do not correctly encapsulate the definition of properties within a database context. For instance, while metadata is an important aspect of information systems, it does not specifically define or equal the properties of database objects. Metadata typically refers to data that describes other data, which can include properties, but is a broader concept. Similarly, properties are not confined to indexing purposes alone; while they may assist in indexing, their primary role is defining the structure of data in terms of attributes. Lastly, equating properties to rows misinterprets
