摘要： One method includes receiving a database query, receiving information about a data source (102) such as a database table (324a, 324b, 324c) in data storage populated with data elements, producing a structural representation (334) of the database table that includes a formatted data organization reflective of the database table and is absent the data elements of the database table, and providing the structural representation and the database query to a plan generator (318) capable of producing a query plan (314). Another method includes receiving a query plan (314) from a plan generator (318), the plan representing operations for executing a database query on a data source (102) such as a database table (324a, 324b, 324c), and producing a dataflow graph (312) from the query plan.
摘要翻译：一种方法包括接收数据库查询，在用数据元素填充的数据存储器中接收关于诸如数据库表（324a，324b，324c）的数据源（102）的信息，产生数据库表的结构表示（334），其包括反映数据库表的格式化数据组织，并且不存在数据库表的数据元素，以及向能够产生查询计划（314）的计划生成器（318）提供结构表示和数据库查询。另一方法包括从计划生成器（318）接收查询计划（314），所述计划表示用于对诸如数据库表（324a，324b，324c）的数据源（102）执行数据库查询的操作，并且生成数据流图（312）从查询计划。

IPC分类号： G06F17/28
摘要： A method, and corresponding software and system, for translating an expression are described. The method includes accepting a first expression (102) in a first syntax, the expression including a first character sequence representing a string value using the first syntax; identifying a second syntax for representing the expression; and generating a second expression (104) in the second syntax representing the first expression, including generating a second character sequence using the first character sequence such that the second character sequence represents the string value using the second syntax.

Another method includes receiving a query plan from a plan generator, the plan representing operations for executing a database query on a database table, and producing a dataflow graph from the query plan, wherein the dataflow graph includes at least one node that represents at least one operation represented by the query plan, and includes at least one link that represents at least one dataflow associated with the query plan.
摘要翻译：一种方法包括接收数据库查询，在数据存储器中接收关于数据库表的信息，生成包含反映数据库表的格式化数据组织的数据库表的结构表示，并且不存在数据库的数据元素表，并将结构表示和数据库查询提供给能够生成表示用于在数据库表上执行数据库查询的操作的查询计划的计划生成器。另一种方法包括从计划生成器接收查询计划，所述计划表示用于在数据库表上执行数据库查询的操作，以及从所述查询计划生成数据流图，其中所述数据流图包括至少一个表示至少一个由查询计划表示的操作，并且包括表示与查询计划相关联的至少一个数据流的至少一个链接。
