data division; data partition (набор строк таблицы, хранящийся отдельно от других наборов строк. Строки группируются в раздел данных в соответствии с условием PARTITION BY оператора CREATE TABLE. См. IBM глоссарий терминов и определений ПО DB2 для Linux, UNIX и Windows ssn); data division (Data division is used to define the variables used in the program. It consists of four sections − File section is used to define the record structure of the file. Working-Storage section is used to declare temporary variables and file structures which are used in the program. Local-Storage section is similar to Working-Storage section. The only difference is that the variables will be allocated and initialized every time a program starts execution. Linkage section is used to describe the data names that are received from an external program.) |
