5. Data Load Differences Between Aggregate Storage and Block Storage

Data Load FunctionalityAggregate StorageBlock Storage
Cells loaded through data loadsOnly level 0 cells whose values do not depend on formulas in the outline are loadedCells at all levels can be loaded (except Dynamic Calc members)
Update of database valuesAt the end of a data load, if an aggregation exists, the values in the aggregation are recalculatedNo automatic update of values. To update data values, you must execute all necessary calculation scripts.
Data load buffersThe loading of multiple data sources into aggregate storage databases is managed through temporary data load buffersNot supported
Atomic replacement of the contents of a databaseWhen loading data into an aggregate storage database, you can replace the contents of the database or the contents of all incremental data slices in the databaseNot supported
Data slicesAggregate storage databases can contain multiple slices of data. Data slices can be mergedNot supported
Dimension build for shared membersFull support for parent-child build method. Duplicate generation (DUPGEN) build method limited to building alternate hierarchies up to generation 2 (DUPGEN2).Support for all build methods
Loading data mapped to datesIn a date-time dimension, you can load data into level 0 members using supported date-format strings instead of member namesDate-time dimension type is not supported
