Info: DriveWorks Limits

This document defines the various limits that apply in various parts of DriveWorks.

SQL Limitations

Some areas of validation in DriveWorks are dependent on SQL Server, SQL Server Express, and SQL Server Compact Edition, an online reference for SQL Server limits is http://msdn.microsoft.com/en-us/library/ms143432.aspx. In addition, rules for identifiers for SQL Server 2000 are taken from http://msdn.microsoft.com/en-us/library/aa223962(SQL.80).aspx.

Excel Limitations

When driving Microsoft Excel documents you will be bound by the limits of the application. The following Excel limits are taken from the Office 2003 limits and specifications document at http://office.microsoft.com/en-gb/excel/HP051992911033.aspx.
