摘要： A scheme is used to automatically discover algebraic constraints between pairs of columns in relational data. The constraints may be “fuzzy” in that they hold for most, but not all, of the records, and the columns may be in the same table or different tables. The scheme first identifies candidate sets of column value pairs that are likely to satisfy an algebraic constraint. For each candidate, the scheme constructs algebraic constraints by applying statistical histogramming, segmentation, or clustering techniques to samples of column values. In query-optimization mode, the scheme automatically partitions the data into normal and exception records. During subsequent query processing, queries can be modified to incorporate the constraints; the optimizer uses the constraints to identify new, more efficient access paths. The results are then combined with the results of executing the original query against the (small) set of exception records.

摘要翻译： 一种方案用于自动发现关系数据中的列对之间的代数约束。 约束可能是“模糊的”，因为它们对大多数但不是全部的记录持有，并且列可以在同一个表或不同的表中。 该方案首先识别可能满足代数约束的列值对的候选集合。 对于每个候选者，该方案通过将统计直方图，分段或聚类技术应用于列值样本来构建代数约束。 在查询优化模式下，该方案自动将数据分割为正常和异常记录。 在随后的查询处理期间，可以修改查询以并入约束; 优化器使用约束来识别新的更有效的访问路径。 然后将结果与针对（小）异常记录集执行原始查询的结果相结合。

摘要： The invention relates to the use of poly-N,N-di-(hydroxyalkyl)-polycarbonamides of aliphatic or cycloaliphatic polycarboxylic acids as reactive flame-retardants for polyurethane foams, and in particular polyurethane integral skin foams and polyurethane rigid foams which are produced with the aid of organic blowing agents. These reactive flame-retardants are added in quantities of from 11.5 to 50 parts by weight, and most preferably from 12 to 25 parts by weight, based on 100 parts of the relatively high molecular weight polyol used for the preparation of the foam. The integral skin or rigid foams produced are flame-resistant and because of their reduced flammability are capable of passing various regulation fire tests, and in particular those testing foams for use in vehicles for transport.
