  2. An edge represents a relationship between two entities (nodes).
  3. A vertex represents an entity (node) in the database.
  4. It makes querying complex relationships faster and easier.

  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. Fore searches on deeper levels using a graph database can be simpler.

  1. What is a graph?

An abstract data used to model data that contains objects and a relationship between those objects

  1. What is an edge?

It describes the relationships between those objects

  1. What is a vertex?

This represents an entity object with its properties that correspond to columns in a relational database

  1. **Why would we want to use a graph database instead of a normal SQL database?

Because of efficiency-you can visually see a high level of data at once so you can track where you want to go quickly

  1. What is a graph?

A graph is a structure amounting a set of objects (also called vertices or nodes) in which some pairs of the objects are in some sense related (each of the related pairs of vertices is called an edge or a line).

  1. What is an edge?

An edge is the relationship between two vertices.

  1. What is a vertex?

Vertices are the fundamental unit of which graphs are formed. A vertex represents an object in the graph database.

  1. Why would we want to use a graph database instead of a normal SQL database?

Because it is more effective at storing a large amount of relationships within the data. It may also offer increased efficiency for searches in some cases.

  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).

A graph database uses its nodes to contain data. Typically a node is used to represent an entity object, and is comparable to a row in a relational database. Each node also contains the properties of that entity, which can be anything the business needs to keep track of (ID numbers, location, etc.) These properties correspond to the columns in a relational database.

  1. What is an edge?

These are use 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.

  1. What is a vertex?

Data that contains objects (referred to as nodes or vertices)…

  1. 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.

  2. A vertex is a node or like a record with its attributes in a SQL database.
  3. A graph database makes it easier for searching for more complex relationships in large amounts of data. Also, directly stating relationships between two objects within a graph database provides a strong advantage over relational database systems for certain datasets.

  1. A graph is an abstract data type that contains objects, as well as the relationship between those objects.

  2. An edge is used to describe a relationship between objects.

  3. A vertex represents an endpoint of an edge, which is a node.

  4. A graph database may be a better choice over SQL when the data contains a lot of relationships between objects and there is a need for increased efficiency in certain types of searches which often require multiple queries in SQL. An example is to get a list of friends-of-friends.

  1. What is a graph?
    Graph is a data type used mostly to model data that contains objects and some sort of relationships between them.
  2. What is an edge?
    Edges are referring to the relationships between the objects
  3. What is a vertex?
    A vertex is a object on that graph data structure
  4. Why would we want to use a graph database instead of a normal SQL database?
    In cases where stating the relationships between objects in a more direct manner would be advantage, the Graph DB are highly recommended (mainly for increased efficiency)

  1. What is a graph?
    Graph is a database model whereby each item/row is represented by a node, and links between nodes represent relationships.

  2. What is an edge?
    An edge represents the direct relationship between nodes.

  3. What is a vertex?
    Vertex is another way of referring to a node, and is the fundamental unit on which a graph is formed.

  4. Why would we want to use a graph database instead of a normal SQL database?
    The ability to detail direct relationships between nodes is 1 advantage, also for data sets that have deeply and complex relational information,

  • A graph is an abstract data type typically used to model data that contains objects, and some sort of relationship between those objects.
  1. What is an edge?
  • An edge is the relationship between the objects in a graph database.
  1. What is a vertex?
  • A vertex is an object on the graph also referred to as a node.
  1. Why would we want to use a graph database instead of a normal SQL database?
  • Using a graph database over an SQL database has the advantage of the ability to directly state the relationship between two objects within a graph database which provides a strong advantage over relational database systems for certain datasets such as an SQL database. It is simply a more efficient and advanced compliment of an SQL database

  1. What is a graph?
  • A graph database is used to model and contain abstract information which can be shown in objects, with their corresponding relationships.
  1. What is an edge?
  • An edge or line denotes the relationship between each node contained in a graph database. They would correspond to a foreign key column of a row in a RDBMS.
  1. What is a vertex?
  • A vertex / vertices or nodes actually hold the information and can be compared to a row in a relational database.
  1. Why would we want to use a graph database instead of a normal SQL database?
  • Graph databases offer the ability to state clearly the relationship between objects and are more efficient with certain types of search criteria, in particular those that contain a large amount of relationships within the data.
