If you just want to create database diagrams (it's not a full documentation of the database) you can use generic diagramming tool.

Exporting sometimes requires programming/customizations.

Mostly non-convenient column descriptions editing (Data Dictionary).

Designed for forward engineering purposes, not really ideal for reverse engineering.

Very complicated and overloaded with features.

Even worse at the maintenance of the documentation. They are good for creating ER Diagrams, but much less for describing data elements (creating Data Dictionaries).

They provide forward and reverse engineering functionalities. There is a large category of tools which are designed specifically for logical and physical engine-independent data modeling.

Slightly more difficult to set up and learnДocumentation generated with Dataedo ( free trial).

They provide more functionalities: advanced authoring, more metadata, database diagrams. Those tools keep data in a separate repository which enables them to gather and store much more metadata and makes them independent on the database platform.

There are tools that go beyond extended property/comment editors and documentation generators - let's call them metadata repositories.

Advanced documentation tools (read/write + metadata + authoring) Redgate SQL Doc description editor and documentation generatorД¦.

Metadata scope limited by database capabilities (you can't add more information than the engine enables).

Ability to describe/annotate data elements (tables, columns etc).

Those tools mostly store metadata (descriptions) in the database itself - in Extended Properties in the case of SQL Server or comments in the case of MySQL and Oracle. Document generation just makes it easier to access and share, while providing descriptions of data structures gets the knowledge out of the peoples heads and saves it for later reference. This is where value added is being created. This category is different from the previous in editing capabilities which is a huge difference as providing the descriptions is a key documentation activity.

generate convenient documents for sharing.

describe tables and columns (data dictionary), or other database objects and.

There is a number of tools that enable you to do both functions of documenting:

Annotating capabilities are limited by database platform (you can't provide rich text descriptions or describe elements if DBMS doesn't support that)Дocumentation generated with dbForge Documenter for SQL Server.

No editing capabilities, separate tool is required for this (e.g.

Better formatting than standard database tools.

This category of tools doesn't have any editing capabilities and can only generate a documentation from metadata extracted from the database. There is a number of dedicated tools whose sole purpose is to generate documentation from your database schema.

SQL Server: SQL Server Management StudioДatabase documentation generated with Oracle SQL DeveloperДiagram generated with SQL Server Management Studio.

No ability to generate integrated documentation consisting of diagrams and detailed data dictionary.

Little or no editing and authoring capabilities (only basic annotation features).

No global documentation for both - objects descriptions and diagrams.

DBAs, developers and architects already use database management tools.

Most of them are free or shipped with the database engine.

Reverse engineering database schema to ER Diagrams.

Commenting data elements (tables, columns, views etc.).

Standard database consoles like SQL Server Management Studio (SQL Server), Oracle SQL Developer (Oracle) or MySQL Workbench (MySQL) support some basic database schema and model documentation and generation. Database development and management tools It also feels more natural since documentation usually has tabular structure.ДЈ. It makes navigating, searching and filtering data more convenient.

It's an even worse nightmare to maintainДЄ slightly better choice for a tool would be a spreadsheet (like MS Excel or LibreOffice Calc).

Good formatting, branding and printing capabilities.

When you want to create a printable document, word processors (like MS Word or LibreOffice Writer) sound like an obvious choice. This article presents 8 different types of tools you can use to create a documentation of your existing databases.
