Experience

Dynamic File Processing Engine

该平台使用户能够处理和分析大量传入和传出的数据. Since every dataset is unique in terms of quantity, quality, and format, the platform allows users to configure the format, specifications, 以及用于处理和管理UI本身数据的业务规则.

引擎使用这些配置，并在处理的各个阶段解释它们. 用于相同操作的底层数据以正确的规范化形式保留在数据集市中，以便在处理吞吐量和数据一致性方面提供最有效的结果. In this way, 客户端避免了格式到格式的硬编码，跨系统的不同平台被集成到一个地方.

用户在界面上配置文件的布局和处理规则. 可以对该处理逻辑进行排序以创建工作流. Internally, all these rules are converted into DRLs. With Drools, 用户驱动的处理可以由用户在UI上创建的规则控制，并在运行时在KIE会话中执行. In these sessions, data was processed in chunks, enriched with third-party APIs (as configured), 并根据频率和FTP/SFTP配置下发.

Real-time Production Control Solution
