摘要： A computer implemented method is provided for processing data representing a data entity having sub entities. The method includes analyzing queries to the data entity for deriving information about sets of the sub entities frequently queried together, and grouping the sub entities to a number of banks, each bank having a maximum width, based on the information about sets of sub entities frequently queried together, in order to reduce an average number of banks to be accessed for data retrieval.
摘要翻译：提供了一种用于处理表示具有子实体的数据实体的数据的计算机实现的方法。该方法包括分析对数据实体的查询，用于导出关于一起经常查询的子实体的集合的信息，并且基于关于子实体的集合的信息频繁地将子实体分组到多个银行，每个银行具有最大宽度一起查询，以减少要进行数据检索的银行平均数量。

摘要： A method for generating occurrence data of data values for enabling encoding of a data set includes determining occurrences of data values in a first data batch and determining occurrence count information for a first number of most frequent data values in the first data batch, the occurrence count information identifying the most frequent data values and their occurrence counts. The method also includes generating for rest of the data values in the first data batch at least a first histogram having a second number of buckets and merging the occurrence count information of the first data batch with occurrence count information of a second data batch. The method further includes merging the first histogram of the first data batch to a merged histogram corresponding to the second data batch and processing a next data batch as a first data batch until the data set to be encoded is processed.
摘要翻译：一种用于产生用于使数据集编码的数据值的出现数据的方法，包括：确定第一数据批中的数据值的出现以及确定第一数据批中第一数量最频繁数据值的出现次数信息，发生次数识别最频繁的数据值及其发生次数的信息。该方法还包括在第一数据批中生成具有第二数量桶的至少第一直方图的剩余数据值，并且将第一数据批次的发生计数信息与第二数据批次的发生计数信息进行合并。该方法还包括将第一数据批次的第一直方图合并到与第二数据批次相对应的合并直方图，并将下一数据批处理作为第一数据批次，直到处理要编码的数据集。

摘要： A cell-specific dictionary is applied adaptively to adequate cells, where the cell-specific dictionary subsequently optimizes the handling of frequency-partitioned multi-dimensional data. This includes improved data partitioning with super cells or adjusting resulting cells by sub-dividing very large cells and merging multiple small cells, both of which avoid the highly skewed data distribution in cells and improve the query processing. In addition, more efficient encoding is taught within a cell in case the distinct values that actually appear in that cell are much smaller than the size of the column dictionary.
摘要翻译：小区特定字典自适应地应用于适当的小区，其中小区特定字典随后优化频分区多维数据的处理。这包括使用超级单元的改进的数据分区或通过划分非常大的单元并合并多个小单元来调整所得到的单元，这两者都避免了单元格中的高度偏斜的数据分布并且改进了查询处理。另外，如果在该单元中实际出现的不同值远小于列字典的大小，则在单元格内教授更有效的编码。
