Everyone who gets a job with the skill this channel teaches, should donate to this channels patreon!

[Arind_om]

This channel is heaven for programmers

[TwoiChai]

For everyone who wants to do this course:
- please do a course for Spring Boot
- Spring Boot Security
- Have good knowledge about Java Core
- Be familiar with crud opearations
- Its is also useful if you know how to use POSTMAN or INSOMNIA

If you don't know the basics it will be realy hard for you and you will lose motivation

Great job. I would like to see Neo4j with python. It would be amazing since Neo4j and Python are very good at data analysis.

[maulikdavra]

This was an excellent project; please keep bringing content like this. content like this will surely attract more Java developers.

[georgefarg]

believe it or not, I was studying Neo4j when I received the notification 😂🎉

[christopherchen]

Fantastic course. Neo4j course ❌ Java Spring Boot Class + neo4j ✔ Really helpful！！！！

A graph is a data structure that can be efficiently implemented using an RDBMS. Facebook, X, and Instagram do not use a graph database like Neo4j, but their own structure. So, do not use small data for examples.

Native graph databases like Neo4j have specific power for large data sets that require such data structure. It is not that RDBMS cannot scale, but when the data structure is graph-related, a native graph database engine will have an edge.

Thank you for sharing this masterpiece!🥰

For the React part, I'm getting a Uncaught TypeError: Converting circular structure to JSON
--> starting at object with constructor 'HTMLDivElement'

[RafaVeraDataEng]

I have no words to transmit you how I appreciate such contents!
For sure a will donate you some, as soon as i get my first job like software developer.

I would like to ask you, how could I create several login roles. i.e: role company clients and in the other side role company employees, and assigning each one, which information they can consult...

Is it so far possible?

Thanks in advance

[micknamens]

24:04 The result would be easier to understand when the rows would also contain the employee id.

The channel is very wonderful, but unfortunately I find it difficult to understand because my English is weak, and the Arabic subtitle is also not good 💔😢

[saumilvachheta]

Hi @freecodecamp, why don't you guys upload videos on Java Related Technologies and Java Projects often. We can see some x/y/z clone projects or end-to-end project on other technologies on your channel, but they are never in Java. Also Full Stack Java Projects(using Spring Boot, Cloud, Docker, Kubernetes). Looks like creators/DeveloperCommunity have/has abandoned us Java Developers. Everybody just posts content on JavaScript/Python. Please upload courses related to Java/Spring Framework Developers often.

[DhirajPatra]

Thank you for a elaborate session with graph db / neo4j.

One query about the employee to find out immediate manager could be easiest way below:

SELECT e.emp_id AS EmployeeID,
e.emp_name AS EmployeeName,
m.emp_name AS ManagerName
FROM employees e
LEFT JOIN employees m ON e.manager_id = m.emp_id;

How do you handle Transactions during saving

[hazychou]

Just love freecodecampe, you guys deserves more donate!

[BoominGame]

Amsterdam, looking good. easy to focus! 😂

[micknamens]

24:19 The repitition cardinality *1..3 in the query is suspicious. We don't know in advance how many REPORTS_TO links there are in advance. How can we specify we want all? In case of cyclic data the query should stop detect already loaded items.
