Data quality solutions can be fully integrated into CRM, ETL (Extract Transform Load), ERP, or BI solutions and have the advantage of being "seamless" to the end user - reducing the learning curve, as well as decreasing the implementation time frames. Your data process flow should not have to be modified to add a new data quality solution. Through integration and strategic partnerships you are assured that you are getting a best-of-breed solution. However, keep in mind it is not absolutely necessary for the solution to be fully integrated. First logic also provides tools that your organization can easily integrate on your own, and oftentimes stand-alone solutions may be more effective for specific projects.
