Database diagram

Posted By:      Posted Date: September 07, 2010    Points: 0   Category :ASP.Net
Hello all, We have been assigned a project for future developement. The problem is original developer did not create any data model, so we are in trouble understanding how db structure flow goes. I know we can create database diagram (even did that), but db contains 162 tables so the db diagram becomes so big that it does not fit in the monitor's view. Viewing each table > keys (for relationships) is not possible. Any suggestions, to make the things simpler.

SQL Server 2008 (Std) : Database diagram distorted on printout



When I create a diagram in MS SQL Management Studio 2008 Std (version see below) I have an ugly mis-rendering on every table on the printout. I have SP2 applied on the client (Managment Studio) and on the server. It looks like "a part of a window" is drawn below each table.

I did:

1. Create new diagram
2. Add Table
3. print diagram to pdf printer or real laser printer

=> same result ugly printout with portion of a window under the table.

I went and used  MS SQL Management Studio 2008 R2. And it worked (from another PC). Directly on the server using SQL 2008 Managment tools it produced the same distorted output.

This is annoying. What am I doing wrong?
Any tips are welcome

Best regards

Database Diagram functionallity


I posted a question before about 2 tables one with a foreign key being that the primary key from the first table. it was student and status

student table has id as primary key incremental identity and status has id as a foreign key from student.

I created the relationship in the diagram between the 2 tables. And I found out that when you create a new student the id is not populated automatically into the status table.

My question is then:

why do we want to create that relationship or others in the diagram? if it is not going to be automatically populated, I needed a trigger to do it.

thanks :)

An Entity Relationship Diagram Example

An Entity Relationship Diagram conveys a lot of information with a very concise notation. The important part to keep in mind is to limit what you're reading using the following technique:

Choose two entities (e.g. Company and Employee)
Pick one that you're interested in (e.g. how a single Company relates to employees)
Read the notation on the second entity (e.g. the crow's feet with the O above it next to the Employee entity).

Multiple database support with Entity Framework

One of the features introduced in Entity Framework is being database independent. Which mean each database provider can support Entity Framework by implementing its provider.

This feature allows you build applications independent from the underplaying database provider. In this post I'm going to show how to build an application that support multiple databases using same conceptual model made by Entity Framework.

Export Visio Database Table Names to Excel

If you use the Enterprise Architect edition of Microsoft Visio for data modeling regularly, then there is a good chance that at some point you've wanted to export just the table names into Excel. You might want to do this to map logical ERD entities to physical data model tables, track project status by entity, or track overlap between database versions.

MS SQL Server: Disconnect Users From Database - Kill User Session

If you ever wanted to restore your database from a SQL backup file (.bak), but there are still users connected to your database, the backup operation will fail causing the error: Exclusive access could not be obtained because the database is in use.

Publishing SQL Server Database using Publishing Wizard : Tips & Tricks

We can use SQL Server Publishing Wizard to deploy our local Database to remote hosting server/production server.This feature is available in SQL Server 2008/VWD 2008.

Below is the complete step by step guide of this process.

UML Diagram Types

UML provides a number of diagram types as a mechanism for entering model elements into the model and showing overlapping sets of models elements and their relationships. UML does not specify what diagrams should be created or what they should contain, only what they can contain and the rules for connecting the elements. The diagram types include:

UML Diagram Types - 2

Further diagram types include:

Activity Diagrams - a generic flow chart used much in business modelling and sometimes in use case modelling to indicate the overall flow of the use case. This diagram type replaces the need for dataflow diagrams but is not a main diagram type for the purposes of analysis and design.

Use Case Diagram

The use case diagram shows the functionality of the system from an outside-in viewpoint.

Actors (stick men) are anything outside the system that interacts with the system.
