Understanding OLE DB terminology Within OLE DB, what do you call the actions that an object can perform (invokable behaviors)?
Correct Answer: Methods.
Introduction / Context:OLE DB is an object-based COM technology. Like other object models, it distinguishes properties (state), methods (actions), and events or notifications. Knowing this vocabulary helps developers read provider documentation correctly.
Given Data / Assumptions:
- We focus on OLE DB's object model abstractions.
- We need the term for invokable behaviors on objects.
- Providers expose objects that clients manipulate via COM interfaces.
Concept / Approach:
In object models, methods are callable operations that cause the object to perform work or change state. Properties represent configuration or state that can be read/written. Collections are containers of objects. Providers supply the OLE DB interfaces; they are not an action themselves. Therefore, the correct term for actions is methods.
Step-by-Step Solution:
Identify the OO concept for actions → methods.Map other terms: properties = state, collections = containers, abstractions = generic concept, providers = component type.Select “methods” as the precise OLE DB term for callable behaviors.Confirm this aligns with COM/OO conventions used by OLE DB.Verification / Alternative check:
OLE DB and COM references consistently use “methods” for callable actions (for example, IRowset::GetData).
Why Other Options Are Wrong:
- A: Properties are values, not actions.
- B: Collections hold multiple objects; they do not define actions.
- D: “Abstractions” is too vague and not a specific OLE DB term.
- E: Providers implement OLE DB; they are components, not actions.
Common Pitfalls:
- Confusing method names with property accessors; both may look similar but have different semantics.
Final Answer:
Methods.
