The company recently acquired Budget Realty, which has a 15-user peer-to-peer network running a FoxPro 5.0 database. The company intends to consolidate both databases into a new database running on a new server environment that requires VPN access. Please recommend a new database platform, migration tools and related steps required for this migration.
My Solution: Michael Lawson
FarPoint Solutions LLC FarPoint is a solutions provider in Simsbury, Conn. The company works closely with Compaq and specializes in thin-client application development. Before I present my solution, its important to describe my companys approach to application development. We specialize in thin-client Internet applications that use a single integrated development environment to produce a single application. Its similar to Citrix MetaFrame and Microsoft Terminal Serverwithout additional licensing costs. Our applications respond, look and feel like standard Windows applications. The development environment we use is Clarion for Windows version 5.5, with the new ClarioNet templates. We would address this particular project in two phases. First, we would analyze the existing database tables to create a data dictionary. This data dictionary would reconcile all the relationships between the individual tables and separate databases. We would then examine the individual applications to determine a common work flow. That initial phase usually takes between 80 and 100 hours and would cost between $8,000 and $10,000, plus out of pocket costs. Depending on the number of processes, forms, tables, reports, and the like, we would be able to come up with a project plan. That project plan would present a detailed strategy and time line for providing LAN access and Internet access. We use encryption technology and a thin-client executable, so no VPN is needed in this solutionjust a single IP address and socket number. Once the analysis is finished we would start the development phase. A typical application can range from $10,000 to $25,000, using the existing data from the data dictionary created in phase one. The applications development can take three to six months. If a conversion is required to something more affordable than Oraclesuch as Microsoft SQL Serverthen the application costs can range from $20,000 to more than $100,000 and are usually completed in one calendar year. Most application development of this type with a minimum feature set (i.e. replace the functionality of the previous applications, plus a few additional features) generally cost in the neighborhood of $50,000 and takes less than nine months to develop using a single programmer. That is achievable due to the fact that most of the design work is done in phase one using the data dictionary. Using Extreme Programming techniques with a programmer on the clients staff realizes even faster deployment times and cost savings. Visit www.extremeprogramming.org for more information. Using the median case presented in this article, Ive provided a cost breakdown, including a price for each component in the solution.
