- A graph is an abstract data type typically used to model data that contains objects (referred to as nodes or vertices), and some sort of relationship between those objects (lines or edges)
- A Edge indicates the relationship between the nodes or vertices
- A vertices is a data object or node and is the equivalent of a row of data in a relational DB
- Graph DBs are more advantageous than Relational DBs when complex multi-level searches between nodes or vertices will be a major requirement when determining the appropriate DB to implement.

- What is a graph?
A graph is a type of database that structures data as objects that are connected to each other (called nodes or vertices)
- What is an edge?
An edge is what describes the relationship or connection between two nodes. This functions similarly to a foreign key column in an RDBMS.
- What is a vertex?
Vertices are objects/nodes. This could be a person, a department, etc. Comparable to a row in a relational database.
- Why would we want to use a graph database instead of a normal SQL database?
Using a graph DB can provide easier organization of data in some cases and make searching for complex data reports faster and more efficient.

Graph data base is better to use compared to SQL database because it gives a better and easier visual of relationships in complex data sets.

- A Graph DB is a DB represented by nodes who contain the information of rows & columns in a table.
- The edges are the relationships between those nodes.
- No idea ? this word is not mentioned in the reading pageā¦
- Graph DB is better when we need to do complex searches like two levels down or more. It allows to retreive and visualize the information much quicker than using a SQL data base, in which you would have to do several searches to get to the same result.

A Graph is basically a dots and lines database, each dot is basically an entity and there is a line either from or to another dot that it somehow relates directly or indirectly to each other. A Dot is basically a node and a node can kinda be compared to a row in Relational Database.
-
An edge is some type of a relationship between 2 nodes
-
Vertex is basically a node
-
The Graph database is much more efficient in finding those indirect relationships between data.

3. What is a vertex?
A graph database uses nodes to represent data as an Entity or Object, with all his properties(attributes).
Also known as vertex or vertices which is an entity such as a person, place, object or relevant piece of data and edges , which represent the relationship between two nodes.
Here you can find even more information about the subject: Graph database Wikipedia or Introduction to Graph Databases
Hope you find this useful! 
If you have any doubt, please let us know so we can help you!

- The relationship between objects in a graph

graphing is the abstract visual display (model) of data
a vertex or node is one data point of reference
the edge is the visual display of the relationship between vertices.
the ability to read complex data quickly. it is sort of like looking at binary code, then itās corresponding Hex code, then finally the QR code

an abstract data type that usually models data that contains objects/nodes and the relationships between them - What is an edge?
they connect between each node describing the relationships of the databases between them - What is a vertex?
a node; contains the data - Why would we want to use a graph database instead of a normal SQL database?
when your searches are typically more than one level deep itās more efficient
when your database contains alot of relationships you are able to directly state the relationship between those two objects

Graph Databases Homework Reading Assignment
- What is a graph?
- Graph databases are a type of NoSQL database, created to address the limitations of relational databases like SQL. A graph database is a mathematical representation of objects or entities or Vertexes(nodes/circles) and their relationships also known as Edges/connecting lines. Each one of those points can represent different things depending on what you want.
- What is an edge?
- Similar to SQL the foreign key is used to link corresponding data in different tables, rows and columns, in Graph databases an edge is the relationship or link between the 2 vertexes/nodes that it connects.
- What is a vertex?
- A vertex hold the information of an entity such as a person, place, object like a Registred data in a ledger, and the Edges, which represent the relationship or link between two nodes/vertexes.
- *Why would we want to use a graph database instead of a normal SQL database?
-
Graph databases may not be the optimal choice for every business, but they have their advantages in certain situations.
-
The ability to directly state the relationship between two objects within a graph database provides a strong advantage over relational database systems for certain datasets.
-
The primary difference is that in a graph database , the relationships are stored at the individual record level (vertexes), and can handle a large amount of relationships within the data.
-
While in a relational database , the structure is defined at a higher level (the tables). Relational databases use less storage space, because they donāt have to store all of those relationships (second layer relationships).

What is an edge?
Graph databases also contain edges between each node. These are used to describe the relationships between the objects contained in the database, and in most they can be compared to the foreign key column of a row in a RDBMS. -
What is a vertex?
A Vertex or node represents an entity such as a person place or object , and is comparable to a row in a RDBMS. -
Why would we want to use a graph database instead of a normal SQL database?
Graph databases are more advantageous over SQL as they allow for simplified and direct data searches for databases containing a high-level of relationships.

It is good to use when you have large quantities of data and a large amount of relationships within the data. Besides that these databases makes it easier to make deep level searches.

The ability to directly state the relationship between two objects, in a database that contain a large amount of relationships is advantages.
Increased efficiency for searches in some cases. (multi level deep searches)
