In a data entry form, when a calculation (formula) is embedded in the form definition itself, what is typically stored or persisted by the application?

Introduction / Context:
Forms can include computed controls that derive values from other fields (for example, amount = quantity * price). Understanding what is stored helps maintain data integrity and avoid redundancy. Typically, the form contains the expression, while the database stores source fields; the computed value is rendered at runtime unless explicitly persisted to a column.

Given Data / Assumptions:

• The calculation is part of the form's design (formula in control properties).
• No separate bound field is defined to store the computed result.
• Reports may display the calculated value without persisting it.

Concept / Approach:

Embedding a formula in a form means the application saves the expression (metadata) with the form definition. At runtime, the form engine evaluates the formula using current record data. Unless bound to a physical column, the computed result is not stored in the database; it is transient and recalculated upon viewing or printing reports. This avoids duplication and update anomalies.

Step-by-Step Solution:

Verification / Alternative check:

Common desktop DB tools (e.g., Access, 4D) and web forms evaluate control formulas on the fly; only bound fields persist to tables unless explicit computed columns exist.

Why Other Options Are Wrong:

‘‘Result stored with the form’’: Results are dynamic; storing them with the form would desynchronize data.

‘‘Result printed in report’’: Reports may show results, but that is output, not what is stored.

All of the above: Not all statements are simultaneously true.

Common Pitfalls:

Persisting derived values unnecessarily, causing inconsistencies when source fields change.

Final Answer:

the calculations are stored with the form
