Systems and processes for accessing data from a graph database are described. The system receives a request comprising time-based information. Time-based information of the request is compared with a first time interval, which is associated with at least one node of a graph. The node of the ...
To show you the true power of graph data modeling, we’re going to look at how we model a domain using both relational- and graph-based techniques. You’re probably already familiar with RDBMS data modeling techniques, so this comparison will highlight a few similarities – and many differen...
数据模型 DataModel 在Nebula Graph 中,每个顶点被建模为一个key-value,根据其 vertexID(或简称 vid)哈希散列后,存储到对应的 partition 上。 image.png 一条逻辑意义上的边,在 Nebula Graph 中将会被建模为两个独立的key-value,分别称为out-key和in-key。out-key 与这条边所对应的起点存储在同一个 partitio...
This tutorial is designed to help you understand how to model your data based on what you intend to use it for. You will use theMovies example datasetas the main resource. For an interactive course on the fundamentals of data modeling, seeGraphAcademy. ...
Property graphs are used to model relationships among data, and they enable query and data analytics based on these relationships. A property graph has vertices that can contain detailed information about a subject, and edges that denote the relationship between the vertices. The vertices and edges...
Graph databases provide a query language (e.g., Cypher for Neo4j, SPARQL for RDF databases) that allows you to express complex graph patterns and retrieve data based on the relationships between nodes. Queries can traverse the graph by following edges, filtering nodes based on properties, and ...

Nebula Graph data model uses six data structures to store data. They are: graph spaces vertices edges tags edge types properties Graph spaces: Graph spaces are used to isolate data from different teams or programs. Data stored in different graph spaces are securely isolated. Storage replications,...

Diffusion model也就是所谓的扩散模型,是当下非常火热的生成式模型。本节的内容并不是跟踪diffusion系列最新的进展,而是对diffusion最经典的工作进行梳理。Diffusion模型需要的数学理论涉及统计、随机微分方差等,哪怕是数学专业的研究生,如果不是相关领域的可能也不会了解这方面的知识,所以还是有一定的门槛。下面的理论基础...
