A data processing method, comprising: acquiring to-be-stored data in a data table in a columnar database; and determining, according to a set storage column width and a column attribute of the to-be-stored data, continuous space of a disk cylinder that needs to be allocated; dividing and/or combining all columns of the to-be-stored data according to the storage column width to convert all the columns into at least one standard column, and recording conversion information, wherein a column width of the standard column is the storage column width; and dividing, according to the continuous space of the allocated disk cylinder and a set section storage size, each standard column obtained after conversion into more than one section, wherein a size of each section obtained by means of division is the set section storage size; and storing same-row data of the to-be-stored data in a same disk cylinder, and in the disk cylinder, successively storing data in each section of columns, wherein a local device comprises at least two platters, and the storing same-row data of the to-be-stored data in a same disk cylinder, and in the disk cylinder, successively storing data in each section of columns comprises: marking, by means of hardware, start positions of different platters that constitute a same physical cylinder, wherein the start positions of all the platters are aligned with each other on the same physical cylinder; and simultaneously storing, starting from the start positions, sections of all the standard columns obtained after conversion in all the platters of the same physical cylinder, wherein data of each section is successively stored in sequence, and all data sections have a same data row quantity. acquiring to-be-stored data in a data table in a columnar database; and determining, according to a set storage column width and a column attribute of the to-be-stored data, continuous space of a disk cylinder that needs to be allocated; dividing and/or combining all columns of the to-be-stored data according to the storage column width to convert all the columns into at least one standard column, and recording conversion information, wherein a column width of the standard column is the storage column width; and dividing, according to the continuous space of the allocated disk cylinder and a set section storage size, each standard column obtained after conversion into more than one section, wherein a size of each section obtained by means of division is the set section storage size; and storing same-row data of the to-be-stored data in a same disk cylinder, and in the disk cylinder, successively storing data in each section of columns, wherein a local device comprises at least two platters, and the storing same-row data of the to-be-stored data in a same disk cylinder, and in the disk cylinder, successively storing data in each section of columns comprises: marking, by means of hardware, start positions of different platters that constitute a same physical cylinder, wherein the start positions of all the platters are aligned with each other on the same physical cylinder; and simultaneously storing, starting from the start positions, sections of all the standard columns obtained after conversion in all the platters of the same physical cylinder, wherein data of each section is successively stored in sequence, and all data sections have a same data row quantity. marking, by means of hardware, start positions of different platters that constitute a same physical cylinder, wherein the start positions of all the platters are aligned with each other on the same physical cylinder; and simultaneously storing, starting from the start positions, sections of all the standard columns obtained after conversion in all the platters of the same physical cylinder, wherein data of each section is successively stored in sequence, and all data sections have a same data row quantity.
