![]() What is worth mentioning, you can document how to join tables across different databases and even engines. Manual relationships are displayed as dotted lines. To define a new relationship right-click the child table, choose Add relation, drag to the parent table and left-click. You can create manual relationships between tables (and views) that would be only preserved in the Dataedo repository (with no impact on the database). One of the key benefits of diagrams in Dataedo is the ability to supplement table joins that have no foreign keys defined in the database. Or double click entity on the diagram to switch visibility of specific columns: Simply right click entity or blank diagram pane and choose one of the options: You can decide on specific columns, tables, or the entire diagram. To add a table to the diagram double click item on the list.īy default, only key columns are included in the diagram, but you can decide which columns you'd like to show. You can use the search field to find a specific table by its name. ![]() This list includes all entities (tables and views) in the repository and highlights the ones linked to the ones already on the diagram and the ones assigned to this particular subject area (subject area groups tables and other objects). Let's move to the ERD tab with a diagram pane and a list of available entities (on the right). Now, as we have a subject area, we can start creating our ER diagram. Enter name and confirm with Enter (to change name press F2). In the repository explorer subject areas & ERDs under documentation element, right click and choose Add subject area/ERD. ![]() You can have an unlimited number of subject areas (diagrams) and diagrams can contain entities from the entire repository (you can create cross-database diagrams). subject areas are objects existing solely in the Dataedo repository and are used to organize databases into smaller pieces, document subject areas, or create diagrams. ![]() Create a subject area for the diagramĭiagrams in Dataedo are held in so-called "subject areas". Now choose your DBMS, provide connection details (more on that here) and follow the wizard to import schema to the repository. Click Add documentation and choose Database connection. Now you need to connect to your database and add new documentation to the repository. To create a file repository click the Create file repository button on the welcome screen. If you want to get started with this tutorial quickly then try the file first. In shared repository - advised (requires SQL Server).Build definitions and descriptions of all tables and columns in a shared repositoryįirst, you need to download and install Dataedo on your computer.ĭataedo has two options to store metadata:.Keep all diagrams in a shared repository (for all databases and DBMSes).Hide unnecessary information from (columns, joins).Keep diagrams in sync with database schema.Explain and document table relationships and joins, including cross-database.Share diagrams in interactive HTML pages easily.Easily create small manageable diagrams for your databases (even the large and complex ones).Here's a summary of what you can gain using Dataedo for your diagrams: This is a quick tutorial on how to create ER diagram for your existing relational databases with Dataedo in just a couple of minutes.
