...
Since SQL Server is (1) made by Microsoft, and (2) the Microsoft database platform, both ODBC and OLE DB are a natural fit for it.
ODBC
Since all other database platforms had ODBC interfaces, Microsoft obviously had to provide one for SQL Server. In addition to this, DAO, the original default tec...

Running PostgreSQL in memory only
...?
No, it is not possible. PostgreSQL is implemented in C and compiled to platform code. Unlike H2 or Derby you can't just load the jar and fire it up as a throwaway in-memory DB.
Unlike SQLite, which is also written in C and compiled to platform code, PostgreSQL can't be loaded in-process either....
Why no love for SQL? [closed]
...an't just compile+run the same C code just anywhere, it's a point for more platform indifferent languages. But it doesn't make SQL nor C "crap": the abstraction layers run top of the deeper layers, anyway.

What is the memory consumption of an object in Java?
...ayen's answer, and JavaWorld.)
Typically, references are 4 bytes on 32bit platforms or on 64bit platforms up to -Xmx32G; and 8 bytes above 32Gb (-Xmx32G). (See compressed object references.)
As a result, a 64-bit JVM would typically require 30-50% more heap space. (Should I use a 32- or a 64-bit ...
What is the difference between JAX-RS and JAX-WS?

How does the main() method work in C?
...nts, then it finds argc and argv as the two topmost stack items. If it's a platform-specific three-argument variant with an environment pointer (a common extension), that will work too: it will find that third argument as the third element from the top of the stack.
And so a fixed call works for al...
Correct format specifier to print pointer or address?
...ing you don't mind the vagaries and variations in format between different platforms, is the standard %p notation.
The C99 standard (ISO/IEC 9899:1999) says in §7.19.6.1 ¶8:
p The argument shall be a pointer to void. The value of the pointer is
converted to a sequence of printing characters...
