If there are no fixed relationships in the database, then you are going to need to try and work it out from the columns in the table to see if they refer to other tables. I've worked with systems in the past where the relationships are not managed by the database (no idea why), rather they are managed via code in the application that owns the database. As the application support contract didn't allow direct access to the database, it didn't matter particularly.

you can use database diagrams to check the relationships between the tables visually and easily in one shot....<br />

You can use the below video link to generate a database diagram in your database.<br />

I need to find out the types of relationship between my tables in the database (1to1 or 1toMany etc).<br />
<br />
Are there any good queries to find out the relationships between my tables in the database? Thanks.<br />

Office Productivity refers both to the act of being productive and efficient in an office or professional environment, as well as the software applications used to "produce" information. This includes the development of professional skills, creating work processes, and almost any program used to create or modify a document, image, audio or video clip. However, business application suites such as Microsoft Office, which include word processing, spreadsheet and presentation programs, are typically called productivity software, as contrasted with a "utility program," such as a file manager, which is used to organize files and folders on the computer. Many office- and business-oriented groups of programs are organized into suites.
