We have been developing and maintaining multi-user Microsoft Access databases, utilizing Access and SQL Server as data repositories, for over ten years. Access is an excellent, low cost, development platform for data entry and analysis, allowing our clients to leverage data in local databases as well as interacting with data in existing enterprise databases (SQL Server, Oracle, mySQL, Access, and even Excel). Access can link to data in any of these (and many other) data sources to minimize redundant data entry, decrease opportunities for data entry errors, and improve our ability to create applications and reports which pull data from multiple sources.
