In section Theory. Referential data usage specifics we have mentioned that the platform has a cache that stores object data read from the database. Now we will discuss this feature in more detail.
1C:Enterprise caches database objects that are read from the database using object operations.
When you access object attributes using a reference, the platform accesses the object cache that is stored in RAM.
The object cache consists of two parts: the transactional cache and the standard cache. Which cache is used depends on whether the reference is made in the context of a transaction or not (fig. 14.33).
Fig. 14.33. Object cache
All the data stored in the cache is intended to be read-only. This means that all the data that is read by reference is handled using the object cache, while writing is handled using 1C:Enterprise object operations.
