- A graph is a data type which main feature is its astraction, which is used to model data containing objects (nodes) and relationships (lines).
- Edges are used to represent relationships between objects in a graph.
- Vertices are used to represent the objects within the graph.
- It is better if we want to represent data which have multiple relationships between large amount of data, and those relationships may change over time. All of these features are not provided by SQL.

A vertex (also known as a node) is an object in a graph database.e.g. customer name, productâŚ

When we have a database that contains large amount of relationships between objects, a graph database would be more efficient.

1.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).
2.Edges 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.
3.Graphs are collections of vertices (points) also know as Nodes and possibly edges (lines) connecting them. You can have a graph without edges, containing only vertices but if you have edges though they must connect two vertices.
4.It depends on the data. A example a Graph database can be used instead of SQL database is a professional network where interconnected knowledge domains, companies, job seekers, job opportunities and skills intertwine. The graph database could be the glue that connects you and a friend of a friend of a friend to your perfect candidate.

They describe the relationships between the objects contained in the database .
What is a vertex?
A vertex is a node or like a record with its attributes in a SQL database.
Why would we want to use a graph database instead of a normal SQL database?
Graph databases may also offer increased efficiency for searches in some cases. The best example of this is when a business needs to perform a search that is more than one level deep.

Why would we want to use a graph database instead of a normal SQL database?
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. Namely, those that contain a large amount of relationships within the data. Graph databases may also offer increased efficiency for searches in some cases. The best example of this is when a business needs to perform a search that is more than one level deep.

1. What is a graph?
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).
2. What is an edge?
These are used to describe the relationships between the objects contained in the database. Comparable to a foreign key in a relational database.
3. What is a vertex?
Vertices are objects such as people or artifacts (generally have properties).
4. Why would we want to use a graph database instead of a normal SQL database?
Relationships are fundamental to how objects interact with one another and their environment. Graph databases are the perfect representation for those that contain large amounts of relationships between objects.

Graph is an abstract database that uses it nodes to represent an entity object, and is comparable in a rational database. Each node contains properties of that entity. These properties correspond to the columns in a rational database.
-
An edge is used to describe the relationships between the objects contained in the database. in most cases, they can compared to a foreign key column of a row in RDBMSâ.
-
A Vertex is a Node with the attributes of a SQL Database.
-
If you want to have more complex queries and you have allot of data in different relationships, then Graph Database can be used. The advantage is that it can handle stating relationships that contain a large amount of relationships within the data.

An edge is a representation of the relationship between two nodes/vertex in a graph database, connecting the vertex together.

A vertex is an entity within a graph database which is comparible to a column in an SQL relational database cointaining all of the properties of said entity.
-
A graph database is a better choice when a database cointains a large number of relationships between entities. It is beneficial as it can allow search functions to be quicker in organisations/databases where there are multiple layers such as having to search for a particular market of a business (ie medicine) and then a particular location/branch then within that branch a department and so on.
Also it can directly state relationships.
