    • A system and method for migrating legacy database systems to modern database comprises generally of the steps of gathering design information about the legacy database system; analyzing the metadata, data fields, and processes of the legacy system; iteratively creating business objects to represent the migrated data; iteratively associating each of the fields of the legacy database system to one or more of the business objects; creating a data migration script to effect the migration of data; and resolving inconsistencies between the legacy database systems and the one or more target database systems.
    • 用于将旧数据库系统迁移到现代数据库的系统和方法通常包括收集关于遗留数据库系统的设计信息的步骤; 分析传统系统的元数据,数据字段和过程; 迭代地创建业务对象来表示迁移的数据; 将遗留数据库系统的每个字段迭代地与一个或多个业务对象相关联; 创建数据迁移脚本来实现数据迁移; 并解决遗留数据库系统与一个或多个目标数据库系统之间的不一致之处。

    • The present invention discloses an improved information security system and method. A polymorphic engine is used to enhance the security features of a software application and the data generated by or made available to the application and/or the operating system. The polymorphic engine operates to randomly alter the standard executable code of the original application while preserving its functional characteristics. Each polymorphed instance of the application differs from any other instance of the same application in form only. Various other security features operate to protect the polymorphic engine itself and/or the polymorphed code generated therefrom. These other security features include: just-in-time instruction code decryption; virtual CPU instruction code pre-processing; call mutation; stack manipulation; secure hook-capture of device input; secure display device output; application level decryption of encrypted hardware data streams; and a dynamic, randomly configured graphical keypad interface.
    • 本发明公开了一种改进的信息安全系统和方法。 多态引擎用于增强软件应用程序的安全特征以及由应用程序和/或操作系统生成或可用的数据。 多态引擎可以随机改变原始应用程序的标准可执行代码,同时保留其功能特性。 应用程序的每个变形实例与仅在形式中的同一应用程序的任何其他实例不同。 各种其他安全特征用于保护多态引擎本身和/或由其产生的多变形码。 这些其他安全功能包括:即时指令代码解密; 虚拟CPU指令代码预处理; 调用突变; 堆栈操纵 设备输入的安全钩捕获; 安全的显示设备输出; 加密硬件数据流的应用级解密; 以及动态随机配置的图形键盘界面。
