Batches: A Unified Approach to SQL, RPC, and Web Services

This session covers batches, a new approach to cross-platform distributed objects (RPC), SQL database access, and Web services. Multiple operations on an SVC interface, including iteration and conditional code, can be lifted out of client code and executed efficiently on the server in one round-trip while all data is being transferred in bulk. Batches eliminate the need for remote proxies, serialization, server facades, and data transfer objects. Remote ops are expressed in Batch Script, a simple scripting language designed to express batches of operations on a server. Batches guarantee a constant number of SQL queries, no matter how many nested loops are used. Batches, which can be used as an alternative to Language-Integrated Query (LINQ), are available now in an experimental JDK 7 fork.
