Reverse Engineering

Available Data Providers are:

  • Native Connection

Native Connection:

Though SQLite database is case insensitive, Reverse Engineering in Toad Data Modeler is case sensitive. This leads to a problem that e.g. when a column name is "ATR" and an index is defined with column name "Atr", the names do not get paired and an error message is thrown.

If some object name includes UTF characters, then the object does not get loaded during Reverse Engineering.

Appropriate SQLite3.dll library is necessary for successful connection.


  1. On page Options, the Load Some Objects as SQL Sentence Only checkbox is applicable for Views, Triggers and Virtual Tables. If selected, triggers are loaded as they are saved in system table.
  2. During Reverse Engineering, objects from only one database are loaded. Therefore, database name is not loaded during Reverse Engineering.
