  • A
    Properties.
  • B
    Collections.
  • C
    Methods.
  • D
    Abstractions.
  • E
    Providers.

Answer

Correct Answer: Methods.

Explanation

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.
