The computer technology of behavioral healthcare information systems must meet at least twelve requirements to effectively support clinical and management operations. Existing, antiquated "legacy" computer systems often fail to meet these requirements, due to high cost, slow turnaround, inconsistent data definitions, duplication, inflexibility and the lack of data integrity. There are five major transitions that an organization's information system undergoes to realize the full potential of new technology: from monolithic to parallel architectures; from procedural to object-oriented programming; from structural to relational databases; from legacy to "leap-frog" systems; and from fragmented systems to multimedia.
行为医疗保健信息系统的计算机技术必须满足至少十二个要求，才能有效支持临床和管理操作。现有的过时“遗留”计算机系统往往无法满足这些要求，原因包括成本高、周转慢、数据定义不一致、重复、缺乏灵活性以及数据完整性不足。一个组织的信息系统要充分发挥新技术的潜力，需经历五个主要转变：从整体架构到并行架构；从过程式编程到面向对象编程；从结构化数据库到关系型数据库；从遗留系统到“跨越式”系统；以及从碎片化系统到多媒体系统。
