    Abstract: An improved data compression method and apparatus is disclosed, particularly for compressing large database tables. A data structure is disclosed which is fully compatible with the traditional DBMS demands, including the random access requirement of RDBMS. The data structure is built on a mixed format physical layout comprising of fixed-sized fields and variable-sized fields which are compressed depending on the size and frequency of the fields. An improved compression ratio is achieved by exploiting redundancy in the mixed format physical layout to encode the column-wise redundancy in the data itself and the correlations among columns. The present invention provides a very fast random access decompression and enables not only greater compression ratios, but also permits flexibility of choosing from a number of compression algorithms.

    Abstract translation: 公开了一种改进的数据压缩方法和装置，特别是用于压缩大数据库表。 公开了与传统DBMS需求完全兼容的数据结构，包括RDBMS的随机存取要求。 数据结构建立在混合格式物理布局的基础上，固定大小的字段和可变大小字段根据字段的大小和频率进行压缩。 通过利用混合格式物理布局中的冗余来对数据本身中的逐列冗余和列之间的相关性进行编码来实现改进的压缩比。 本发明提供了一种非常快速的随机存取解压缩功能，不仅能够实现更大的压缩比，而且还允许从许多压缩算法中进行选择的灵活性。

    Abstract: A toy car includes a housing assembly and a limiting member. The housing assembly is provided with a plurality of wheels rotatable with respect to the housing assembly. The plurality of wheels is configured for engaging on an upper surface of a block and rolling along the upper surface of the block. The limiting member is connected to the housing assembly. The limiting member is configured for abutting against a side surface of the block, and the limiting member is used for limiting the plurality of wheels on the upper surface of the block.

    Abstract: A toy car includes a shell component. The shell component is provided with wheels capable of rotating relative to the shell component. Each of the wheels includes a rolling part and an abutting part. The abutting part is arranged on one side of the rolling part facing away from the shell component. The rolling part is configured to be engaged to an upper surface of a building block and roll along the upper surface of the building block. And the abutting part is configured to abut against a side surface of the building block.
