java vs php benchmark (cited from The Computer Language Benchmarks Game )

I saw a benchmark between Java 7 and PHP. I do not know how precisely the benchmark is. But, I will believe this result. Besides running speed and memory usage, there are many other factors affect us to choose Java or PHP as programming language. But, it is always interesting and valuable to be able to have a rough idea about this kind comparison.

Below is cited from http://shootout.alioth.debian.org/ . Interested can go there for detail.

This chart shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.
Each chart bar shows, for one unidentified benchmark, how much the fastest Java 7 -server program used compared to the fastest PHP program.

Mapping SQL terminology with IBM i terminology

As a IBMi developer coming with background of modern SQL RDBMS, I was always try to "translate" iSerience term like "physical file", "logical file" into SQL terms. Here, I found a table, which maps these terms.

Mapping SQL terminology with IBM i terminology

SQL term	IBM i term
TABLE	PHYSICAL FILE
ROW	RECORD
COLUMN	FIELD
INDEX	KEYED LOGICAL FILE
VIEW	NON-KEYED LOGICAL FILE
SCHEMA	LIBRARY
LOG	JOURNAL
ISOLATION LEVEL	COMMITMENT CONTROLE LEVEL
PARTITION	MEMBER

The table is cited from document IBM DB2 for i indexing methods and strategies
