What is the purpose of a ZC_ table in relation to a _C category column?

• A. To interpret what a category value means
• B. To store user accounts
• C. To hold transaction IDs
• D. To define column order

Answer: (A)

A ZC_ table is a lookup that decodes the codes stored in a C category column. When the main table uses a short numeric or alphanumeric code to represent a category, the ZC table maps each code to a human-friendly description, so reports and user interfaces can show meaningful labels like “Electronics” or “Region A” instead of just 01 or RK. This mapping keeps storage compact while centralizing meaning, making maintenance easier because changes to descriptions happen in one place and can also support multilingual labels if needed. In short, the ZC_ table interprets category values, enabling clear presentation and consistent interpretation across the data model. It isn’t used to store user accounts, transaction IDs, or control column order.
