There is a lot of talk about Progress and SQL in these discussion threads. To be clear ... SOS, Videss and Visualfiles use Progress technology to develop their applications. Whether the back end database is MS-SQLerver or Progress is frankly immaterial. Both can be queried by using SQL (structured query language), both are perfectly adequate DB platforms. That said, the application control layer which is where these vendors put their business logic can abstract the database schema (design). That is why some vendors will try to sell you a data warehouse application so that you can query the database. Visualfiles' ability to connect their Progress client to an MS-SQL backend does provide re-assurance for those comfortable with Microsoft standards. It does not mean that their product is automatically superior or radically different. What distinguishes a good from a bad product is in how you use Progress to build the application. Another trueism is that (software) development tools have limitations. They are getting better, but they can never satisfy all needs. If you use a tool to build your own tool upon - which is what some vendors in the legal marketplace are doing, then the supplier needs to a) understand the foundation tool thoroughly, b) still have a good appreciation of IT fundamentals. Sadly, many of our native suppliers would not know a Codd if it hit them square in the face, could not tell a bit from a byte if it chumped on their posterior. Solicitors are trained professionals. Clients seeking legal advice expect their representatives to be formally qualified. Buyer beware. Check how well qualified your prospective legal IT systems supplier is to develop applications.
