Finally got the error fixed, added locations to the graph and added images of the connections to show the nodes and relationships to my Final Fantasy Tactics to Neo4j project. Check it out if you want.

Hello everyone!

In today's post, we'll discuss the data modeling and schema design for our Golang project, which focuses on analyzing a marketplace's purchase data. This analytical application will help us understand the relationships between sellers, products, and customers, as well as feedback provided by customers on their purchases. The marketplace operates in various locations, including countries and states.

Let's dive into the details of the data schema:

Node types:

Location: Represents a country or a state.

Seller: Contains attributes such as name, locations where the seller offers products, and feedback scores.

Product: Includes attributes like ID, price, and a relationship to its seller.

Customer: Has attributes like ID, location, and represents clients who ordered products and optionally provided feedback on their purchases.

Relationships:

Seller to Location: A many-to-many relationship, indicating the locations where a seller offers their products.

Product to Seller: A many-to-one relationship, connecting each product to its respective seller.

Customer to Product: A many-to-many relationship, representing the products purchased by customers.

Customer to Product (Feedback): A many-to-many relationship, where customers can provide feedback on the products they purchased.

With these node types and relationships in place, we can efficiently model our analytical application about marketplace purchases in a graph database. In the following posts, we'll explore different graph databases and evaluate how well they can handle our data model, in terms of installation, code samples, and performance.

Stay tuned for our next post, where we'll dive into EdgeDB and explore its potential for our Golang project. See you there!

My Goodreads repository now contains a bunch of examples how to interact with CSV data https://github.com/michael-simons/goodreads#interacting-with-the-csv-file, including #sqlite #duckdb #neo4j and #xsv

I’ll be part of the #Bucharest #Techweek in Romania as part of their #Java summit https://www.techweek.ro/java-summit and I’ll discuss an old topic: #database #refactorings and #migrations and why these things make a lot of sense for a #Graph database like #neo4j that is not so schemaless like you would think.

TIL the `guix graph` command has a backend that outputs [cypher queries](https://neo4j.com/docs/cypher-manual/current/) (for use with [neo4j](https://neo4j.com/))

Why can't databases just manage themselves? :blobfoxsad:

Und hier jetzt noch der Workshop-Bericht zum Workshop "Neo4J für Korrespondenzdaten" mit @FKlemstein am letzten Montag:

#Graphen #Neo4J #DigitalHumanities

What a nice message to wake up to. My #Neo4j database #migration and #refactoring toolkit has been featured on #Githubs release radar. https://github.blog/2023-02-08-release-radar-dec-2022-jan-2023/

An #opensource consortium that includes #Google plans to release a deployable beta of the #GUAC project this month, a possible milestone for #cloudnative #SBOM. https://www.techtarget.com/searchitoperations/news/365532041/SBOM-graph-database-aims-to-be-cloud-security-secret-sauce

ETA: As my colleague @robwright astutely noted on the birdsite, this has some potentially far-reaching implications given the #WhiteHouse #NationalCybersecurityStrategy announcement...

Neo4j-Migrations 2.1.2 has been released: https://github.com/michael-simons/neo4j-migrations/releases/tag/2.1.2

This is merely a bugfix release.

Neo4j-Migrations is a database #migration tooling for #Neo4j.

https://github.com/neo4j-contrib/cypher-dsl/releases/tag/2023.1.0

Today we released Cypher-DSL 2023.1.0, the first version that does include a bit of semantic analysis of the #Cypher statements being built or parsed with its parser module.

This will allow for additional verification, checks and possible mappers in Spring Data #Neo4j and other modules.

Big shout-out to @lukaseder for feedback and input and ofc helping us getting a #sql2cypher PoC to work.

Heute fand an der @stabihh im Referat der erste Workshop der Reihe "Digital Humanities - Wie geht das?" statt, bei dem @FKlemstein am Beispiel von Korrespondenzdaten aus der #DehmelDigital Edition in #Neo4J eingeführt hat. Ergänzend dazu gab es fantastisches Wetter und einen tollen Blick über #Hamburg. Einen Workshopbericht gibt es demnächst auf dh3.hypotheses.net.

#DigitalHumanities

Blick in einen hellen Seminarraum, in dem Menschen an einem langen Tisch an Notebooks sitzen, während die Refertin im Stehen etwas erklärt.

Blick über Hamburg mit blauem Himmel und ein paar Wolken. Im Vordergrund die Kuppel des Uni-Hauptgebäudes und der Turm eines Hotels.

#MultilingualDH #DigitalHumanities

I'm impressed: You can write almost all components of a #Cypher command for #Neo4J in Arabic script - and it works! Pain to write it, but still...

Next university project: building a graph database of #Rust dependencies using the #CratesIO database dumps <https://crates.io/data-access> and #Neo4J!
