DB Visual Architect (DBVA) is a powerful tool that provides support for Object Relational Mapping (ORM) and Entity Relationship Diagrams (ERD), which assist with realizing UML designs as relational database implementations. By drawing a class diagram for the system, you can generate the required database tables and persistent source code for database manipulation. It can also be used with existing software.
IT Works is an IT asset management native iPhone application. It lets you store and manage detailed information about computers, devices, and users, using AES-128 encryption from the system-provided frameworks for storing sensitive data such as passwords. A Master Password is set up on first run that both protects access to your information and encrypts your data. When you want to add new information, or edit/delete existing records you must 'unlock' the Application using the Master Password, which will also let you view your passwords in clear text.
