graph is an abstract collection of information that points to objects represented by nodes or vertices connected with lines or edges
a connector; simple line that connects nodes or vertices. (relationship)
vertices are nodes;
to simplify queries of information in SQL databases due to that lines or edges helps find the best search path
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 connect a graph’s datapoints, thereby supplying information about the connection. If there is no connection in accordance with the graph’s parameters, there is no edge.
3.) Vertices are the graph’s main datapoints. These get connected by the aforementioned edges and contain an ID and data in connection with that ID.
4.) It could be a more efficient solution than SQL, depending on the circumstances.
A graph is an abstract data type typically used to model data that contains objects and some sort of relationship between those objects
Edges or lines 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.
Objects in graph are referred to as nodes or vertices
We would use graph database when database contains a large amount of relationships within the data and in cases when we need to perform a search that is more than one level deep.
What is a graph?
An abstract data type typically used to model data that contains objects, such as nodes or vertices, and some sort of relationship between those objects, such as lines or edges.
What is an edge?
an edge is used to describe the relationships between the objects contained in the database, comparable to the foreign key column of a row in a relational database.
What is a vertex?
a node that is used to represent an entity object. It also contains the properties of that entity, comparable to a row in a relational database.
Why would we want to use a graph database instead of a normal SQL database?
When a dataset contains a large amount of relationships within the data.
A graph database has the ability to directly state the relationship between two objects.
It also offers increased efficiency for searches when the data structure is multiple levels deep.
An abstract data type typically used to model data that contains objects
It is used to describe the relationships between the objects contained in the database.
It is used to represent an entity object.
To reduce the number of queries in the database for information.

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.
A1. It is an abstract database
A2. The relationship between objects
A3. It is an object.
A4. When relationship between objects are required within the data

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 such as those that contain a large amount of relationships within the data.

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 is a mathematical representation of objects or entities or nodes and their relationships or edges.
Graph database is an abstract data type which can store large amount of relationships within the data and it is its priority.
Based upon the concept of a mathematical graph it is constructed as collection of nodes and edges, where node represents an object or vertices containing data and the properties of that entity (ID numbers, location, etc.) that correspond to the columns in a relational database,
while the edge or line represents the connection or relationship between two objects/nodes, can be compared to the foreign key column of a row in a RDBMS.
Each node in a graph database is identified by a unique identifier that expresses key value pairs and each edge is defined by a unique identifier that details a starting or ending node, along with a set of properties.
Graph database stores both facts and relationship between facts, making certain type of analysis more intuitive by ability to directly state the relationship between two objects without having to make a hypothesis and test it, also with increased efficiency for searches in complicated cases more than one level deep. Accessing nodes and relationships in a native graph database is constant-time operation and allows you to quickly traverse millions of connections per second per core.
An edge also termed graphs or relationships , are the lines that connect nodes/data/objects to other nodes; representing the relationship between them. It represents a foreign key column of a row, can be be directed or undirected.
Vertex / vertices is node the fundamental unit of which graphs are formed, an entity object with its properties.
A graph, from the article, may be defined as an abstract data type that is used to model data that contains objects and the relationship between those objects.
An edge is located between each node in a graph database and is used to describe the relationship between two objects contained in the database.
A vertex or node is used to represent an entity object and contains data.
It eases the ability to compare the relationship between two objects, especially where large amounts of data are involved. Also searches in a graph database are more efficient.

3. What is a vertex?
Vertex" is a synonym for a node of a graph, i.e., one of the points on which the graph is defined and which may be connected by graph edges. A vertex a represents an endpoint of an edge. An edge joins two vertices a, b and is represented by set of vertices it connects.

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.
