Adobe Acrobat Connect Pro (formerly Macromedia Breeze) is software used to create information and general presentations, online training materials, web conferencing, learning modules, and user desktop sharing. The product is entirely Adobe Flash based. All meeting workspaces are organized into ‘pods’; with each pod performing a specific role (i.e. chat, whiteboard, note, etc.). The recommended database for backend support is Microsoft SQL Server. The product can be licensed as an installed product, or a hosted product.
