Introduction to the Active Everywhere Database

For almost half a century, the relational database management system (RDBMS) has been the dominant model for database management. However, today's business needs are forcing data management into new use cases, such as managing interactions with constantly-connected devices and websites, powering and managing social networks, handling multi-structured data and machine-generated files, etc.
The amount of useful data in some modern application areas has become so distributed and vast, and the speed at which that data moves so fast, that it cannot be stored or processed by traditional database solutions. User-generated content in social networks and data retrieved from large sensor networks are two of the many such examples where traditional relational databases are being pushed beyond their limits.
