Data Modeling
Sigma IT offers consulting on using explicit statistical or artificial intelligence techniques for data modeling. Very often the challenge for successful data modeling is not in identifying the right software package to use but in identifying a company with the right skills to do the R&D.
Sigma IT works with its clients to understand the domain specific characteristic of their problem before embarking on numerical experiments that can span a wide spectrum of modeling techniques. An explicit statistical model may be more suitable for a government department trying to model the behavior of users of its services, while a credit card company may find that artificial neural networks can better capture the characteristics of users close to default. Our consulting services include data cleaning and warehousing, R&D on the applicability of various models to the problem at hand and the design and implementation of turnkey solutions.
When an enterprise's raw data can be turned into strategic information, the benefit to the organization is overwhelming. A database built on a solid logical design, and conversion of that logical model into an efficient physical design is the basis for achieving the competitive edge that companies need in our fast changing world.
