I am studying on a project that requires to manipulate the index data.
I know oracle uses b-tree index as the default structure.. But where
is this structure stored? Is it a table. If so, can I access data (in
the index)?
Can I access the index from outside (from a java application) Actually
I want to "traverse" the nodes of B-tree.
Thanks a lot..

As the topic says, I am wondering how (in Java) I can extract a sub-tree
of a org.w3c.dom.Document and form a brand new one. I use Oracle's
XMLDocument implementation and have been playing around with
DocumentFragment etc. but somehow I always end up creating only the
single node and not its sub-nodes.

Hi,
I'm currently implementing a database with a tree structure in a table. The
nodes in the tree are stored as records with a column called "Parent". The
root of the tree has a "NULL" parent. The path to each node is stored in
the column "Path" and is of the form "\000001\000002\000003\" etc. The
latter enabling me to fetch subtrees using the "LIKE" predicate. I also
have created the relation "ID" <-> "ID_Parent, effectively the...

I would like to perform a schema validation of a DOM tree that is
already assembled in memory with as little fuss and setup as possible.
I see support in the Xerces documentation to perform validation with
DOMBuilder and XercesDOMParser. There is also an interface class
called XMLValidator, but it is not clear to me how I might use these
resources to achieve what I described above. Any help getting started
in the right direction would...

Alright I needed some help regarding a removal of a binary search
tree. Yes its for a class, and yes I have tried working on it on my
own, so no patronizing please. I have most of the code working, even
the removal, I just don't know how to keep track of the parent, so
that I can set its child to the child of the node to be removed.

Hi everyone, I'm wondering whether it's possible to construct a
binary-tree using python.
Since python don't have pointer, it can't dynamically allocate memory
like C language.
But some important data structures like linked list, binary-tree and
hash table are closely linked with dynamic memory technology.
Any help that can be provided would be greatly appreciated.
Thanks in advance

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
