Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0037] The storage structure of this real-time database uses a data structure similar to clustering in the database as the basic data unit, that is, the same type of data is stored centrally. Specifically, each data unit contains a list of the same data type, and only this type of data is stored in the data list, so the space occupied by each data is consistent. This data unit also contains a bitmap established for this data list. The length of the bitmap is equal to the number of data in the list. Each bit in the bitmap corresponds to a data sequence in the list, indicating that this data is available. Used or used. The value of the bit is 0, which means it can be used, that is, new data can be stored; it is 1, which means it has been used, that is, the data has been stored, and it cannot be used for the storage of new data. Because each data is repr...
