Abstract: According to an embodiment of the present disclosures, systems, methods, and non-transitory computer-readable mediums having program instructions thereon, provide for process of segregating data from database tables into different layers depending on the frequency of access to the data—so that each layer of the data can be stored in an appropriate storage mechanism. For example, infrequently-accessed data can be stored in a hard disk drive (HDD) and frequently-accessed can be stored in random-access memory (RAM). Further, the data can also be stored in a sold-state drive (SSD) or other memory-storing devices. In an embodiment, grading attributes are used to layer the data and, accordingly, segregate the data into appropriate storage mechanisms.

Abstract: A method and system for accessing data in a de-commissioned legacy system are provided. Data are automatically extracted from the legacy system, although data structure(s) of the legacy system might not be known, by finding views corresponding to a query for the data. Attributes, metadata, and/or fields (“attributes”) can be parsed from the query. Tables and/or fields including the parsed attributes are identified. Views can be then identified, where the views contain the tables and/or fields including the parsed attributes. The views can be ranked in an order from those that include the greatest number of parsed attributes to those including the least number of parsed attributes. A data request understandable by the legacy system, e.g. a packet, can then be formed using the least number of views, where the views can collectively include all of the parsed attributes.

Abstract translation: 提供了一种用于访问卸载遗留系统中的数据的方法和系统。 尽管传统系统的数据结构可能不知道，但通过查找与数据查询相对应的视图，数据自动从传统系统中提取。 属性，元数据和/或字段（“属性”）可以从查询中解析出来。 识别包括已解析属性的表和/或字段。 然后可以识别视图，其中视图包含包含已解析属性的表和/或字段。 这些视图可以按照包含最多解析属性的顺序排列到包含最少被解析属性的列中。 遗留系统可以理解的数据请求，例如， 然后可以使用最少数量的视图来形成分组，其中视图可以共同地包括所有被解析的属性。
