oracle-r2dbc VS ArangoDB

I blocked oracle.com and java.com at the firewall years ago.

You should also try to install Oracle XE Edition (which is free) and go through all the training materials found on oracle.com.

Thanks everyone for your helpful replies!! On further investigation the site I'm looking at appears to be a "DNS Hosting" site, whatever that is. So it's like "site1.site2.net", but when I take away "site1", "site2.net" automatically redirects to "oracle.com". It seems like the original site is in a kind of public graveyard and it's may be old records, not up to date ones, that were forgotten when things were moved to a new host or whatever (again, I don't have the correct words). So it's probably not as serious a security concern as if it were current information, however still seems like a breach of GDPR at least, as I'm in Europe.

Ok so I am unable to install and use java (I'm just trying to mod minecraft). My problem is that when I install the correct java I need and try to open and install files with java there is no option to open with java after installing it. Ive also tried jarfix but when I open it it says there is no java presence to fix. I've installed on my C drive didn't work on my D drive didn't work ive uninstalled and reinstalled but nothing I'm doing will work I'm unsure if it is because I'm on a laptop or if something just isnt compatible. Also when I go into command prompt and run java --version it gives me errors I have gotten a good result once however that still didn't work. Ive watched a bunch of YouTube videos to see what my problem may be. The process I'm using to install is 1. go to oracle.com 2. download java installer 3. run the installer and install java 3. try and open what I'm trying to install (curse forge) 4. usually uninstall and repeat. PLEASE I need someone's help I really want to know if I'm doing something wrong PLEASE!!!!

I installed Java on oracle.com, and followed all the instructions, I added the path to my java bin file on my environment variable path. I tested it out on cmds and it does seem like I have it, when I did java -version, it outputted

https://oracle.com/ it's easy to find (maximum just google oracle free hosting)

/Library/Java/JavaVirtualMachines is empty, no JDK installation performed from oracle.com or openjdk etc.

- Re-install the latest version of Java from the official site (oracle.com / java.com)

Oracle - Commercial

We're not to that point, so that's why you haven't had that communication. Oracle has been very upfront that closing the deal is but one step in the journey. Onboarding to their HR, their benefits, getting oracle.com email addresses, etc. will all come months later.

ArangoDB

... or working in an environment or on a problem for which functional patterns apply.

Suppose you are writing a "CRUD" app that writes to a relational database, how do you apply functional programming to that? The whole point of an application like that is that it makes side effects.

In some cases you can break those problems down into functional pieces. Consider Python drivers for a product like

https://www.arangodb.com/

One major problem is that you want drivers that work synchronously and asynchronously, the structure of the average api call is something like

   def query(parameters):

First, you need to choose a specific graph database platform to work with, such as Neo4j, OrientDB, JanusGraph, Arangodb or Amazon Neptune. Once you have selected a platform, you can then start working with graph data using the platform's query language.

Some databases like ArangoDB (https://www.arangodb.com/) allow you to use Javascript instead of SQL.

However, using a type-unsafe, turing-complete language introduces type unsafety and turing-complete problems to the query layer; the usual problems we know and love, such as infinite loops, runtime type errors, exceptions, and the like.

Personally, I'm looking forward to a WASM runtime for databases -- so we can run webassembly on the database. This COULD be carefully designed to be statically checked and, possibly, make it really hard to write runaway loops.

When it comes to graphdb's, my favorite is still ArangoDB, definitely worth checking out if you are looking for alternatives.

Personally my favorite db for pet projects is

I think you hear very little about it because ADB users see it as a "secret weapon" to crush their competitors with. I've done large ontology work (MESH and other health ontologies) and IoT work (keep several years of sensor readings for sensors in my house) and workflow systems (select interesting HN articles or jobs I want to apply to) and it has never let me down. I haven't run a real instance serving customers in the cloud though.

For the last few years every eng manager I have worked with has been a fan of

https://www.postgresql.org/

In the early 2000s I thought it overpromised and underdelivered and called it CrashGreSlow but after MySQL got bought by Oracle the pgsql team has worked hard to improve it I think it is great today. It supports all kinds of advanced features such as stored procs, full-text search, JSON equivalent fields, etc.

Hi! I recently came across ArangoDb and used in some POCs, but I really want to know if someone here already used it in a Real World environment or even if chose to not use in a production environment. So... have you ever used ArangoDb? Why? Why not?

For mutual friends, we can build a social graph for every user. Each node in the graph will represent a user and a directional edge will represent followers and followees. After that, we can traverse the followers of a user to find and suggest a mutual friend. This would require a graph database such as Neo4j and ArangoDB.

ArangoDB

This a NOSQL database built for high availability and high scalability, a perfect fit for implementing persistence in microservices. ArangoDB is an open source native multi-model database that supports graph, document and key-value data models allowing users to freely combine all data models in a single query.
