Data integration is critical to the success of enterprises today. Competition constantly drives businesses to find better ways to handle information, including having centralized stores of data available in real-time for informed decision-making; buying new applications that use existing data without adding overhead to existing applications; and improving overall cost-effectiveness and productivity in accessing and maintaining enterprise data. Some of the most challenging data integration scenarios involve gathering data from multiple databases across multiple platforms. Solutions are typically evaluated based on low cost of ownership, respect for the integrity of existing systems, lightweight installation, ease-of-use, predictability, and open, extensible architecture.
This white paper presents the issues facing businesses with data integration needs. It then compares the business value of the principal approaches to database integration: doing it yourself, investing in a single-vendor enterprise solution, or integrating data via specialized tools to provide an accelerated custom solution.
