Welcome at Dolphin's Design


You are invited to use our Software & Publication Services for your business, your organisation or your private needs. Our Services comprise general as well as application specific help and support, analyses of situations and applications, design and development of software applications including databases, full application testing with recommending improvements, as well as the production of publications such as flyers, brochures and books. We are specialised in using the Microsoft Office (e.g. Excel) and Microsoft Office Access (e.g. SQL, VBA) products. Please see our Services for more details.


You are also invited to use and to recognise the benefits of our fully customised and easy-to-use OPAL Addresses and Dossier Management System (CRM). This application is commercially proven and used by various organisations successfully every day since more than two decades. OPAL is a user-friendly and professional dossier management system (CRM) for all activities and documents, with integrated contact and address management, as well as the project administration. OPAL can also be used as a pure address management system. However, you will very soon honour the additional benefit of the integrated dossier management as well.


OPAL can be used on a professional business network server with several client workstations just as well as on a private personal computer. OPAL runs fully independent from Internet availability, but offers all needed connectivity (e.g. sending e-mails, using hyperlinks) if Internet is available. Therefore, you are always in full control of your OPAL data and documents. Here are 7 OPAL highlights:

  1. Address management for unlimited addresses (with international address formats) and for unlimited numbers for each organisation and for each person.

  2. Relations management for unlimited relations between organisations, persons and projects.

  3. Dossiers for a well targeted overview to all activities of a person, organisation or project. Each dossier may contain unlimited activities, documents and pending files and provides various search and filter functions. Documents may be OPAL-Documents, which are stored in the OPAL database, as well as externally stored and linked files (all file types are supported).

  4. Text processing (highly automated OPAL-Documents) for the efficient, quick and user-friendly creation of letters, mailings, notes and other documents (for printing, sending via fax and e-mail).

  5. Stationery (user defined) to automatically being used for the creation of letters, mailings, notes and other documents.

  6. Integration of all external files (e.g. Microsoft Word, Excel, Adobe PDF, etc.) with unlimited hyperlinks.

  7. E-Mail Client to directly send individual e-mails and personalised e-mail mailings and newsletter, which are automatically archived in all relevant dossiers. The e-mail client needs an Internet connection (third party fees may apply).

In addition to its user-friendly data entry and data administration (including «Smart-Filter» in selection lists), as well as all necessary tools for the technical administration and data security (including user codes and passwords), OPAL offers a wizard to import existing person, organisation and address data from any database or table (e.g. Microsoft Excel). Due to the design and the flexibility of OPAL it is possible to store all data in a way to represent the reality. The dossiers for each person and for each organisation will be created and maintained automatically by the usage of OPAL.
