Question 12
A new application needs developing that pulls data from an Access database. Data comes from a variety of tables and views. However, none of the data will be change in any way and data will only be read in a forward only manner. To achieve the design of the application you have decided to create a common data access method which can be reused in your project. You want this method to perform as fast as possible.
Which object should you use to read the data given these requirements?
DataSet
oleDBDataReader
DataView
DataTable
That was the correct answer, well done!
Sorry, that was the wrong answer
The correct answer is oleDBDataReader. This object gives you fast, forward only, read-only view of data. It’s the best object to use if you want fast access to read only data.
