Sentenium has developed and honed advanced procedures that ensure data quality, integrity, and accuracy throughout the course of our clients' research projects. Everything we do is in keeping with evolving market research industry standards.

Our proprietary tracking technology, STracker, ensures that every document or survey we process is "visible" and accounted for through every stage of processing. We can track every document or survey, and every single data file connected to a document or survey, with a unique code. This is especially relevant when dealing with relational databases (such as Microsoft Access, Quattro, mySQL, and Oracle), since by definition such databases involve multiple data files which depend on each other.

At our clients' request and/or our recommendation, we also perform additional validation techniques such as:

• Data / Range checks: We use these checks to identify invalid data, such as data that is not within a stated or logical range.
• Double verification: We have separate people enter data into a system manually, and both sets of data are compared against the original documents received.
• Duplicate case checks: We uncover and correct situations where, for example, one individual has multiple identification numbers. This is especially relevant when working with relational databases.
