BaseNow depends on OLE DB providers and ODBC drivers that provide a standardized access to a range of database formats. Some drivers/providers only partially support features you can expect from a relational database system. For example, you can open the text file and transform the data into some other format, but since the ODBC driver for text files does not support updating, it cannot be edited. There are many other similar issues. Below is a list of known limitations, all the bug fixes, and workarounds.
