Predictive dialers are outbound call processing systems that are designed to maintain high levels of activity and provide cost efficiency in contact centers. These dialers are capable of calling a list of telephone numbers automatically, screening unnecessary calls such as answering machines and busy signals, and connecting waiting representatives...
BASE may be explained in contrast to another design philosophy - Atomicity, Consistency, Isolation, Durability (ACID). The ACID model promotes consistency over availability, whereas BASE promotes availability over consistency.
Experts have noted that BASE requires a level of "failure," or lack of consistency, that makes a data operation run less effectively without overburdening users. An example is when a designer relaxes the consistency of a financial transactional database by allowing for lag time between a transaction and account updates. Allowing less constantly updated data gives developers the freedom to build other efficiencies into the overall system.

In BASE, engineers embrace the idea that data has the flexibility to be "eventually" updated, resolved or made consistent, rather than instantly resolved.
