• Connection Management:
  • multiple server connections
  • connection over ssh tunnel
  • keep a connection alive

Each diagram can keep one or few tables of a database, links between them, labels with your comments and so on. Diagrams are stored in the .vdb file as part of your database schema.

• Encrypt/Decrypt Objects - you can encrypt/decrypt a database, table or field.

• Multi-Table Browsing - you can select few tables, and get a list of all their fields in the single-column then filter it. This feature simplifies the work with databases with a big amount of tables and fields.

  • Column View - this view is similar to Finder look of MAC OS X.
  • Diagram View - this allows you to see tables and links in a visual way.

• Tree View - is a traditional hierarchical tree to which windows users are used. This view allows browsing properties of some object family easily.

• Sorting Records - you can easily sort records of the Table by single column by click on its header. Next click will change the direction of sorting from Ascending to Descending, and next click removes sorting by this column at all. First 2 states are indicated by small triangle icon in the column header.
