My test program below is in the form of a single JSP, with a Node class

In scanning a drive and comparing file content, I need to remember
filepaths to every single file I encounter so I can take actions on
certain files later on.
Rather than having a huge list enumerating the complete filepath to
every file it seems the smarter way (faster, more memmory efficient) is
to model the filesystem treestructure in a abstract tree - and having
only the filenames & node pointer in an Array.

Hey!
Can anyone give me a hint, how this problem is best implemented:
I have a table of users (see below), where every user has one
"superior user" (= parent node), this should be a fully unambigous
tree structure. The root node can have whatever value you prefer, I
suppose NULL would be good for a start. What I want to do is finding
the way from an arbitrary node in the tree.
Example:

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...

Hi everyone,
I would like to hear your opinions about a design solution I am
contemplating.
The problem I am following: Write an editor for a data structure that is
recursive in nature. In other words it is a tree, where child nodes can
contain links to parent nodes. And there multiple kind of nodes: Here is an

I have a data set which I need to analyze but I am having a problem
figuring out a structure for the database - or whether there are better
ways of attacking the problem.
The base data set is a large number of replies to a survey
questionaire. I have adapted a NLP program to produce lexically annotated
structural trees which appear to reasonably accurately reduce the text to
descending trees. These trees consist of multiple nodes each...

actually i want to generate a tree structure on client side, the application is simple web based, and need to display the data extracted from the database to client in tree structure. but the problem is that i need to display the tree of the data in tabular format, means expanding of tree should expand the table rows and collapsing of tree should collapse the table rows.
if any one knows the way to do this, plz help me out.

I'm not sure if this discussion is a better fit for the Access or XML forum and I don't want to double-post, so I'm starting in Access because you've been so helpful to me here.
I am preparing a presentation comparing using a relational database vs. a native XML database within a content management system to manage XML-based documentation. The point I am trying to make is how difficult it can be to reconstruct the XML hierarchy/tree once the...

Hi there!
I'm facing an issue concerning tree data structure in php.
In others languages, I just need to create a root node which I bind
pointers of instances representing others nodes.
But I couldn't find a way to do so in php language. Indeed, object
instances are "volatile" reaching the end of the script. How could I
build a tree with "volatile" address pointers in php ?
I could use arrays to store data like a tree structure but I'd...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
