Best for interactive applications. The adapter fills a DataSet (an in-memory cache of data). This allows users to edit data offline and then "sync" those changes back to the database in one go. 4. The Modern Approach: Entity Framework (EF)
Best for "firehose" scenarios where you need to read a large amount of data quickly in a forward-only, read-only stream. It’s memory-efficient because it doesn't load the entire dataset at once. Practical Database Programming with Visual Basi...
Always use Parameterized Queries . By using placeholders (like @ID ), you ensure the database treats user input as literal data rather than executable code. 3. Choosing the Right Tool: DataReader vs. DataAdapter VB provides two primary ways to handle results: Best for interactive applications
