Currently all screenshots of modeler are done in OS X. I don't have Mac, so
could someone update the second screenshot on this page?

> Reverse Engineer Database
>
> *Start Reverse Engineering.* To reverse engineer a database you need to
> select either a DataDomain or one of its children on the project tree. Then
> select "Tools > Reengineer Database Schema" from the menu. "Connect to
> Database" dialog will be presented.
> Reverse-engineering behavior is sensitive to the current project tree
> selection. If you selected a DataDomain or a DataNode, a new DataMap will be
> created and all reengineered tables will be put in this DataMap. If you had
> an existing DataMap (or one of its entities) selected when you started
> reverse engineering, new tables will be merged into the existing DataMap.
>
> *Configure Database Connection.* "Connect to Database" dialog allows to
> specify alternative connection parameters. If a DataNode was selected when
> reverse engineering started, its connection information is shown by default.
> You can use suggested default connection, select one of the stored local
> DataSources from "Saved DataSources" dropdown (those can be edited on the
> spot by clicking "..." button), or type your own info. When desired
> connection is selected, click "Continue". Cayenne will attempt to connect to
> the database and if connection is successful, "Select Options" dialog is
> presented.
>
> *Configure Options.* "Select Options" dialog allows to specify what needs
> to be reverse engineered. If a database supports schemas, one of the listed
> schemas should be selected. Table and stored procedure patterns allow to
> control which tables/procedures are included in reverse engineering.
> Patterns should be in the format used by SQL LIKE clause (e.g. "ABC", "ABC%"
> or" %" or "A%T", etc.).
>
> *Naming strategies.* Since Cayenne 3.0 you can obtain control over
> DbRelationship, ObjEntity, ObjAttribute and ObjRelationship names
> generation. This is achieved by implementing
> org.apache.cayenne.access.reveng.NamingStrategy interface. Modeler itself is
> distrubuted with two default strategies.
>
> org.apache.cayenne.access.reveng.BasicNamingStrategy generates names in
> Cayenne 2.0-style. Thus, to-one relationships will be prefixed by "to",
> to-many relationships will be postfixed by 'Array'. Examples of such names
> are "toArtist" and "paintingArray".
>
> org.apache.cayenne.modeler.util.SmartNamingStrategy uses FK column names
> for to-one relationship names (e.g. if FK column is called "ARTIST_ID" or
> "ARTISTID" the relationship's name will be just "artist"). To-many
> relationship names are pluralized forms of other-side entities names, e.g.
> "paintings". Pluralization is done in rules of English language using
> Inflector <https://inflector.dev.java.net/>.
>
> To use one of predefined strategies or your own one you must specify
> strategy class name in "Naming Stragegy" field of "Select Options" dialog.
> JAR with user strategy must be attached using Tools->Preferences->ClassPath
> bookmark. NamingStrategy implementation must have a public default
> constructor.
>
> *Running Reverse Engineering.* After desired options are selected, click
> "Continue". Progress dialog will open. It will close automatically when
> reverse-engineering is done. After that all database tables and stored
> procedures that matched selected criteria will be added to the DataMap.
> Default ObjEntity mapping will be created as well.
