Such databases are closer to the real-world enterprise use cases. As you can do in our interactive visual designer.ĪdventureWorks is a large sample database produced by Microsoft and used for its SQL Server RDBMS. However, the generated images are always static, in the sense you cannot manually grab a shape and drag it elsewhere.
Graphviz is strong at diagram layouts, so we let it do its job. Layout is always different, because we never send current shape positions to the Graphviz Online app. The database diagrams don’t have to be identical, but we use here very similar styles. We found this fdp image pretty interesting: Switch this time between the existing layout engines. Some shapes are collapsed (with their name only), others fully minimized (like plain bubbles):Įxport now this customized diagram into another Graphviz DOT file, and paste its content into your Graphviz Online application, like before. We displayed simplified shapes with corners, relationships with plain lines, shape items with collapsible categories (hidden relationship items), and no icons at all. We switched to a MySQL Workbench-like theme. Like no other database diagram viewer, Model Xtractor allows you to collapse or minimize shapes, hide individual shape items, move shapes around as you wish, display many-to-many conceptual relationships (bypassing the hidden intersection table), or show relationships as special shape items.įollowing diagram is just a customization of the previous automatic view.

Or it may not show the tables in best possible way. However, it may not be always suitable for what you need. Model Xtractor has one Auto Layout command, that we automatically call last for any of these demo models. the table and view columns.įollowing database diagram is the generated structural model for the Sakila database sample included in MySQL: We call it structural because most tables are expanded and show their structure, i.e. Upon establishing a database connection and importing its metadata, a structural database model, with tables exposing their columns and main relationship connectors, is also generated and open on screen. Structural Database Diagrams on Graphviz Online Several types of database diagrams are then automatically generated. They can quickly connect to and extract table and view information from a variety of relational databases, including Oracle, DB2 and Microsoft SQL Server, PostgreSQL and MySQL/MariaDB, SQL Anywhere and SAP/Sybase ASE, SQLite and Firebird, Microsoft Access and SQL CE.

But you can use our free Model Xtractor or Data Xtractor applications to do that. Neither Graphviz nor any Graphviz Online app can extract schema information from a database, to produce a model. Display the Preview pane and, each time you select a Graphviz file exported from Model Xtractor, its graph will be instantly rendered beside. gv/.dot file visualization support in the Preview pane.
