We recommend a program for learning Crystal Reports under. NET and a good assistant for ms SQL Server.

Haha, the question is long, but it is indeed worth recommending. Recently, I was working on a project change. I got a database of ms SQL Server 2000, and about 60 tables. To get a clear view of its structure, I started to use Visio for reverse engineering, however, the results are not very good. The reverse chart is messy and needs to be arranged neatly manually. I saw a foreigner's introduction on codeporject.com today. It feels very good to run this web Program, You only need to enter the database name, user name, and password of SQL Server, you can use the Crystal Report method, print all the tables in the database according to their structure (just like using "design" in SQL Server to view the table structure), such as field type, length, description, decimal places and so on (of course, you can add other things in the same principle ).
I tried it. It feels good and the effect is good.
The introduction and download of this program can be found here: http://www.codeproject.com/useritems/dbadoc.asp

PS: note that this program is for vs. NET 2003 and crysal report 9 or above. First, as mentioned in the article, you can create a virtual directory in IIS and direct it to the client directory in the project.
Note that if the description in the SQL Server field uses Chinese characters, a box is displayed in the PDF file after the export of the Crystal Report. The solution is, find the schema in this program. RPT report template file, select its description Report field, and change its font to to display and print it normally.
It is worth mentioning that the program is well written and highly scalable, especially if it is needed. Net is a good demo program for learning Crystal Reports.
