OLE DB roles and terminology:\nAre the users of OLE DB functionality called data providers (rather than consumers)?

Difficulty: Easy

Correct Answer: Incorrect

Explanation:


Introduction / Context:
Object Linking and Embedding Database (OLE DB) is a COM-based data access architecture. It defines a clear separation between components that supply data and components that use that data. This question checks whether you know the correct names for those roles.



Given Data / Assumptions:

  • OLE DB defines standardized interfaces for data access.
  • Two key roles exist: one that exposes data, and one that consumes it.
  • The statement claims that “users” are called data providers.



Concept / Approach:
In OLE DB terminology, providers expose data through OLE DB interfaces (for example, an OLE DB Provider for SQL Server). Applications that use those interfaces are called consumers. Therefore, labeling users as providers inverts the roles and is incorrect.



Step-by-Step Solution:
Identify the actor that owns and exposes the data source capabilities → provider.Identify the actor that calls the provider’s COM interfaces to retrieve or manipulate data → consumer.Since “users of OLE DB functionality” call into providers, they are consumers, not providers.



Verification / Alternative check:
Examples include “Microsoft OLE DB Provider for SQL Server” (the provider) used by an application (the consumer) via ADO or native OLE DB.



Why Other Options Are Wrong:
Role names do not change with MDAC version or cursor engines; “provider vs. consumer” is a core architectural distinction.



Common Pitfalls:
Confusing ADO objects (Connection/Recordset) with OLE DB provider components; assuming “user” equals “provider.”



Final Answer:
Incorrect
