I am interested in creating a map of my database, so that I may understand it better. I am having difficulties understanding which tables relate to other tables, and I think a map, or flowchart would help me greatly. Has anyone done this? If so, how did you accomplish it?
You can try SQL Server Management Studio Express. Just right click on Database Diagrams and create a new diagram. You can select existing tables that you desire.
You can follow an excellent guide step by step here.
If you have Microsoft visio, that's a good software in creating a flowchart.
I use Lucid Chart (www.lucidchart.com) occasionally because we don't have Visio either. They offer a free account, which works pretty well, apart from the limit on the number of items you can put in one document (I want to say it's a limit of 60 entities).
Is there any way to auto create ERD of any existing CRM applicaton.
I have MS CRM 11 On Premise and want to take a short look on entities and their relationship diagram. Do we need to create it manually by digging one by one entity and their relationship or is there any other way or any tool do it ?
OR This is not a valid question at all ?
Ideas will be appreciated if any.
Thanks in advance.
You should check out this article on MSDN. The section at the bottom titled Generate Entity Diagrams with the Metadata Diagram Tool describes how to use a program from the SDK to generate an ERD.
I'm a university student who is completely new to SQL and I don't know what I'm doing, so go easy on me. I have been given an assignment to design a Facebook-like database for a website for people who read books. I have made a very basic data dictionary which gives the general idea.
Is this a valid approach? Is there a better way of doing this? I'd appreciate any feedback I can get.
First of all, I would say good to see your efforts.
Here I would suggests you bit enhancements. Instead of maintaining different tables for
books_liked,books_read,wish_list, etc., you can maintain same with the help of flags in the master table books. This is to normalize your data.
eg. flg_liked, flg_wish_list, flg_read
