The Stamp feature displays the information about a database diagram and serves to identify a printed copy of the document. For instance, a hyperlink to wiki pages with database documentation. You can also add hyperlinks to other resources inside your note. The Note feature allows you to add comments to the diagram area while designing or analyzing a database structure. You can create new database objects or edit the existing ones on the diagram area.Р В РІР‚СњР В РІР‚С›ll the changes you have made to an object on a diagram are permanent and stored on the server.

There are many ER diagram tools, with different relative merits. To access the Creating and editing relations option, right-click the line between two entities in the diagram area and perform the following tasks: Good collection of theory and best practices Good vendor and tool support Good DBMS support Popular Some Disadvantages of ER diagrams: Limited expressiveness Not concise Can be ambiguous No standards: many versions that can be confusing Mostly for relational database only. It connects the database designers to the rest of the development team and business users.Creating and editing database objects on a diagram

DeZign for Databases serves as a powerful communication tool. A data model can also be useful to the end user in verifying that all of their data needs have been captured accurately.

The best software tool for drawing Entity-Relationship Diagram is ConceptDraw DIAGRAM vector graphics software with Entity-Relationship Diagram (ERD) solution from Software Development area which gives the ability to describe a database using the Entity-Relationship model. You can generate database documentation and share these models with other members in your team. Entity Relationship Diagram (ERD) is the world-known way to show the logical structure of databases in visual manner. DeZign for Databases allows you to create, annotate and distribute visual data models with industry standard notations.

DeZign for Databases is capable of generating intelligent database update scripts to keep your data model and database synchronized.Р В РІР‚СњР В РІР‚С› data model/diagram provides developers and users a much better understanding of the database architecture. You can modify the model and then synchronize it with your database. You then have a good overview of the database structure. ) and automatically generate Entity Relationship Diagrams/models of existing (complex) database schemas. DeZign for Databases can generate the SQL to create the database or it can generate the database directly.Р В РІР‚СњР вЂ™Р’ВeZign for Databases can connect to data sources (Oracle, MS SQL Server, PostgreSQL, MySQL, SQLite, MS Access. When you are ready with the data model, DeZign for Databases generates the database you designed. You draw entities (tables), add attributes (columns) and create relationships between those entities. You can design or model your database visually before you write a single line of database code. It 'converts' the diagram into database commands and DDL (forward engineering). The tool can generate SQL scripts (DDL) or a database from the content of a data model (ERD). After importing the structure of an existing database you can modify/redesign your model and regenerate or synchronize it with your database. With DeZign for Databases you can draw new ERD's or reverse engineer existing databases and derive an Entity Relationship Diagram from that database.

Relationships describe the relations between the entities.

Attributes are the data we want to collect for an entitiy.

An entity is a person, place, thing or event.

Entities are the 'things' for which we want to store information.

There are three basic elements in ER-Diagrams: For a good database design it is essential to have an Entity Relationship Diagram. An Entity Relationship Diagram shows entities (tables) in a database and relationships between tables within that database. An Entity Relationship Diagram (ERD) is a snapshot of data structures.
