Working with Cached Updates

From InterBase

Go Up to Developer's Guide

Cached updates enable you to retrieve data from a database, cache and edit it locally, and then apply the cached updates to the database as a unit. When cached updates are enabled, updates to a dataset (such as posting changes or deleting records) are stored in an internal cache instead of being written directly to the dataset’s underlying table. When changes are complete, your application calls a method that writes the cached changes to the database and clears the cache.

This chapter describes when and how to use cached updates. It also describes the TIBUpdateSQL component that can be used in conjunction with cached updates to update virtually any dataset, particularly datasets that are not normally updatable.
