Question: Can you explain the difference between an ADO.NET Dataset and an ADO Recordset?Answer: Valid answers are:路A DataSet can represent an entire relational database in memory, complete with tables, relations, and views. 路A DataSet is designed to work without any continuing connection to the original data source. 路Data in a DataSet is bulk-loaded, rather than being loaded on demand. 路There's no concept of cursor types in a DataSet. 路DataSets have no current record pointer You can use For Each loops to move through the data. 路You can store many edits in a DataSet, and write them to the original data source in a single operation. 路Though the DataSet is universal, other objects in ADO.NET come in different versions for different data sources. |
