CRAM’s expertise lies in:


Data mart
Data Mart is the simplest form of data warehousing that focuses on single functional area such as sales, finance or marketing. Data marts are mostly created and controlled by a single department within an organization. Given their single-subject focus, data marts usually draw data from only a few sources. A data mart can also be referred to as access layer of data warehouse environment utilized to get data out to users..

Online analytical processing (OLAP)
OLAP is marked by relatively lesser number of transactions. Queries are often very complex and involve aggregations. For OLAP systems the measure of effectiveness is its response time. OLAP applications are widely used by Data Mining techniques. OLAP databases store aggregated historical data in multi-dimensional schemas (usually star schemas). OLAP systems typically have data latency of a few hours, as opposed to data marts, where latency is expected to be closer to one day

Online Transaction Processing (OLTP)
OLTP is marked by a large number of short on-line transactions (INSERT, UPDATE, and DELETE). OLTP systems rely on very fast query processing and maintaining data integrity in multi-access environments. For OLTP systems, effectiveness is measured by the number of transactions per second. OLTP databases contain detailed and current data. The schema used to store transactional databases is the entity model (usually 3NF). Normalization is the norm for data modeling techniques in this system.

Predictive analysis
Predictive analysis is about finding and quantifying hidden patterns in the data using complex mathematical models that can be used to predict future outcomes. Predictive analysis is different from OLAP in that OLAP focuses on historical data analysis and is reactive in nature, while predictive analysis focuses on the future. These systems are also used for CRM (Customer Relationship Management).
