Resource constrained wireless computing devices (e.g. mobile telephones) are given a replication capability for database records (e.g. to enable backing up contacts, e-mails, photographs etc. onto a remote server). This operates without undue processing burden, using low bandwidth unreliable wireless connections. This is achieved by not including a time stamp in each database record, but instead time stamping only a change log record; this approach saves considerable memory space on the wireless device since there is no need to time stamp every database record, as is usually done in the prior art. The change log defines what data is to be replicated; it alone has to be sent to a main server which hosts a master copy of the database and hence has to be kept up to date. Because the change log is compact, far less data has to be sent for data replication purposes—typically only the field which has changed, how it was be changed and when it was changed on the wireless computing device. Prior art systems typically send an entire record, even though that will contain data that has not changed.

Disclosed is a system for caching data. After determining a sequential access of a first memory area, such as a direct access storage device (DASD), a processing unit stages a group of data sets from the first memory area to a second memory, such as cache. The processing unit processes a data access request (DAR) for data sets in the first memory area that are included in the sequential access and reads the requested data sets from the second memory area. The processing unit determines trigger data set from a plurality of trigger data sets based on a trigger data set criteria. The processing unit then stages a next group of data sets from the first memory area to the second memory area in response to reading the determined trigger data set.
