Free cross platform database management tools software for linux

SIMD Cross-platform headers is a cross- platform, cross-compiler, cross CPU C/C++ header collection that aids the creation portable vectorized (SIMD) C/C++ code.
SIMD Cross-platform headerst supports (or partially supports) x86 (MMX/SSE/SSE2) GCC and MSVC, PPC Altivec GCC and CodeWarrior, ARM GCC, and software-emulated SIMD.
NOTE: Code must be 16-byte aligned. Align to 16 when allocating memory.
X86/XSCALE (Intel) vs. PowerPC/MIPS
While the PowerPC and MIPS SIMD instructions take 2 source vectors and a destination vector, the Intel platforms only take a source and destination. Example:
PPC/MIPS can do:
C = A + B
X86 can only do:
A = A + B (or A+=B)
Code written either way will work on the X86, and still be faster than 387 math, but preserving the registers takes significant overhead (Disassemble the test program for an example. The prints preserve, the disassembly test does not.) For the fastest code between systems, write your SIMD math as the X86 expects, manually preserving SIMD variables.
At least GCC for PPC doesnt seem to have any issues figuring out how to deal with a source and destination memory address being the same.
Enhancements:
- Created file with some i386, GCC dialect

iODBC is a cross-platform Driver Manager that comforms to the Microsoft ODBC 2.x & 3.x and X/Open SQL CLI data access specs.
iODBC Driver Manager and SDK enables the development of database-centric solutions that are both database and platform independent.
What is the ODBC Value Proposition?
The ability to develop applications independent of back-end database engine.
What is iODBC?
iODBC is the acronym for Independent Open DataBase Connectivity, an Open Source platform independent implementation of both the ODBC and X/Open specifications. It is rapidly emerging as the industry standard for developing solutions that are language, platform and database independent.
What is the iODBC Value Proposition?
The ability to develop applications independent of back-end database engine, operating system, and for the most part programming language. Although ODBC and iODBC are both C based Application Programming Interfaces (APIs) there are numerous cross language hooks and bridges from languages such as: C++, Java, Perl, Python, TCL etc.
iODBC has been ported to numerous platforms, including:
Linux (x86, Itanium, Alpha, Mips, and StrongArm), Solaris (Sparc & x86), AIX, HP-UX (PA-RISC & Itanium), Digital UNIX, Dynix, Generic UNIX 5.4, FreeBSD, MacOS 9, MacOS X, DG-UX, and OpenVMS.
This is a great SDK for porting WIN32-based ODBC applications to Linux and other OS platforms.
Enhancements:
- Added support for FileDSN
- Added support for Connection Pooling
- Added check for tracefile size
- Call ODBC 2.x functions in driver if application uses ODBC 2.x only calls
- Fixed problem parsing driver result in SQLSetStmtAttr
- Fixed source code readability
- Fixed bug in overwriting driver name
- Fixed check for /Library/ODBC for Mac OS X
- Fixed prototypes
- Rewrote bootstrap script and configure summary
- Use localtime_r in tracing when available
- Fixed build issues with Mac OS X
- Small code cleanups and fixes

- Smart Features

HTTPD::GroupAdmin is a Perl module for the management of HTTP server group databases.

SYNOPSIS

use HTTPD::GroupAdmin ();

This software is meant to provide a generic interface that hides the inconsistencies across HTTP server implementations of user and group databases.

METHODS

new ()

Heres where we find out whats different about your server.

Some examples:

@DBM = (DBType => DBM,
DB => .htgroup,
Server => apache);

$group = new HTTPD::GroupAdmin @DBM;

This creates an object whose database is a DBM file named .htgroup, in a format that the Apache server understands.

@Text = (DBType => Text,
DB => .htgroup,
Server => ncsa);

$group = new HTTPD::GroupAdmin @Text;

This creates an object whose database is a plain text file named .htgroup, in a format that the NCSA server understands.

Full list of constructor attributes:

Note: Attribute names are case-insensitive

Name - Group name

DBType - The type of database, one of DBM, Text, or SQL (Default is DBM)

DB - The database name (Default is .htpasswd for DBM & Text databases)

Server - HTTP server name (Default is the generic class, that works with NCSA, Apache and possibly others)

Note: run perl t/support.t matrix to see what support is currently availible

Path - Relative DB files are resolved to this value (Default is .)

Locking - Boolean, Lock Text and DBM files (Default is true)

Debug - Boolean, Turn on debug mode

Specific to DBM files:

DBMF - The DBM file implementation to use (Default is NDBM)

Flags - The read, write and create flags. There are four modes: rwc - the default, open for reading, writing and creating. rw - open for reading and writing. r - open for reading only. w - open for writing only.

Mode - The file creation mode, defaults to 0644

Specific to DBI: We talk to an SQL server via Tim Bunces DBI interface. For more info see: http://www.hermetica.com/technologia/DBI/

Host - Server hostname

Port - Server port

User - Database login name

Auth - Database login password

Driver - Driver for DBI (Default is mSQL)

GroupTable - Table with field names below

NameField - Field for the name (Default is user)

GroupField - Field for the group (Default is group)

From here on out, things should look the same for everyone.

add($username[,$groupname])

Add user $username to group $groupname, or whatever the Name attribute is set to.

Fails if $username exists in the database

if($group->add(dougm, www-group)) {
print "Welcome!n";
}

delete($username[,$groupname])

Delete user $username from group $groupname, or whatever the Name attribute is set to.

if($group->delete(dougm)) {
print "Hes gone from the groupn";
}

exists($groupname, [$username])

True if $groupname is found in the database

if($group->exists(web-heads)) {
die "oh no!";
}
if($group->exists($groupname, $username) {
#$username is a member of $groupname
}

list([$groupname])

Returns a list of group names, or users in a group if $name is present.

@groups = $group->list;

@users = $group->list(web-heads);
user()

Short cut for creating an HTTPD::UserAdmin object. All applicable attributes are inherited, but can be overridden.

$user = $group->user();

(See HTTPD::UserAdmin)

convert(@Attributes)

Convert a database.

#not yet

remove($groupname)

Remove group $groupname from the database

name($groupname)

Change the value of Name attribute.

$group->name(bew-ediw-dlrow);

debug($boolean)

Turn debugging on or off

lock([$timeout]) =item unlock()

These methods give you control of the locking mechanism.

$group = new HTTPD::GroupAdmin (Locking => 0); #turn off auto-locking
$group->lock; #lock the objects database
$group->add($username,$passwd); #write while database is locked
$group->unlock; release the lock
db($dbname);

Select a different database.

$olddb = $group->db($newdb);
print "Now were reading and writing $newdb, done with $olddbn";
flags([$flags])

Get or set read, write, create flags.

commit

Commit changes to disk (for Text files).
