The correct answer is: B. is a standard way of organizing information into accessible parts.
A logical schema is a standard way of organizing information into accessible parts. It is a conceptual model of the database that describes the data and the relationships between the data. The logical schema is independent of the physical storage of the data.
A logical schema is not the entire database. The entire database includes the logical schema, the physical schema, and the data itself. The logical schema is just one part of the database.
A logical schema is not a description of how data is actually stored on disk. The physical schema describes how data is actually stored on disk. The logical schema is independent of the physical storage of the data.
Therefore, the correct answer is: B. is a standard way of organizing information into accessible parts.
