So that the store could be updated in a single transaction during the replication process, group memberships were limited to 5000 members. In Windows Server 2003, Linked Value Replication removes this limitation

b. At the source site, repopulate the streams data dictionary for the object or granularity required using any of the following procedures. DBMS_CAPTURE_ADM.PREPARE_TABLE_INSTANTIATION from:http://www.itpub.net/thread-1200526-1-1.html#
While traditional LbSM use coarse-grain page append granularity, SIAS performs appends in tuple-version granularity and manages versions as simply linked lists, thus avoiding in-place invalidations. Our experimental results instrumenting a SSD with TPC-C generated OLTP load patterns show that: a) ...
Moreover, the term “atomic data” shall be understood to refer to the lowest level of data granularity required for effective decision making. In the case of a retail merchandising manager, atomic data may refer to information by store, by day, and by item. For a banker, atomic data may...

The two modes of organization described above represent extremes of a wide space of possible schemes: while coordinate/value pairs have the finest granularity (single positions) and, consequently, the largest number of items, the domain/range representation consists of one single “monolithic” item....

The granularity of the MLPPI for a specific workload may also be an issue. Fine-grained partitions potentially can lead to less I/O, since the amount of data to be accessed is reduced. However, numerous partitions can have potential overhead from an optimization and execution perspective. ...
Atomic data refers to the lowest level of data granularity required for effective decision making. In the case of a retail merchandising manager, “atomic data” may refer to information by store, by day, and by item. For a banker, atomic data may be information by account, by transaction,...
