  1. What is a graph?
    A graph is a collection of data nodes whereby each node contains all the properties for that entity.
  2. What is an edge?
    A edge is a relationship from one node to another node.
  3. What is a vertex?
    A vertex is another name for a node.
  4. Why would we want to use a graph database instead of a normal SQL database?
    Depending on the data being represented, a graph database might prove more efficient to query than an SQL database.

  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?
    It’s an object

  3. What is a vertex?
    It’s a relationship between objects

  4. 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. As an example, let’s consider a database storing corporate structure information.

  1. What is a graph?**
    -a data type that contains nodes (or vertices) connected by lines (or edges)
  2. What is an edge?**
    -some sort of relationship between nodes
  3. What is a vertex?**
    -nodes, or vertices, are objects in the graph.
  4. Why would we want to use a graph database instead of a normal SQL database?
    -the relationship is presented in the graph, easier to visualize in complex relationships, also can have increased efficiency when searching

  2. Edges 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.
  3. A Vertex or Node is used to represent an entity object and is comparable to a row in a relational database .
  4. When the data and the associated relationships are best represented in a graphical format.

A graph is a data representation typically used to model data that contains nodes or vertices (objects), and lines or edges that represent the relationship between those objects .(lines).

  1. What is an edge?
    A line used to describe relationships between the objects.

  2. What is a vertex?
    A object connected by edges in the data model,

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

  1. A graph is used to model data. The data is represented in nodes and relationships are defined between the nodes.
  2. An edge is used to describe the relationships between the objects contained in the database.
  3. The article doesn’t say anything about a Vertex, but according to Google a Vertex in computer graphics is a data structure that describes certain attributes, like the position of a point in 2D or 3D space, or multiple points on a surface.
  4. A more simple approach to searching for data. It’s easier and makes discovering the many relationships between data easier to comprehend.

  • What is a graph?
    It is an abstract data type used to model data that contains objects and shows the required relationship between those objects.

  • What is an edge?
    An edge describes the relationship between objects in a database.

  • What is a vertex?
    Vertices or nodes are the entity objects in the database. They carry the properties of anything a business entity wants to keep track of.

  • Why would we want to use a graph database instead of a normal SQL database?
    Because a graph database has the ability to show directly many relationships among objects.

Reading Assignment: Graph Databases

1. What is a graph?

It’s a abstract datatype typically used to model data that contains object(nodes called Vertex), that have some relationship between the (lines called edges)

2.What is an edge?

It’s the links(relations) between Vertex( nodes ) , they can be compared to foreign keys columns in a RDBMS

3.What is a vertex?

It’s a node(circle) in the Graph database, that for the most case have a link(edge) to another node(Vertex)

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

Where there are a need of stating relations between objects (Vertex) , where the needs is to related to each other in some way. I believe it’s the optimal database for research of DNA/biological data, to find relations in genetic material.

  1. What is a graph? It’s an abstract model data type that contains nodes that have relationships with each other

  2. What is an edge?
    It’s a line used to describe the relationships between nodes

  3. What is a vertex?
    -It’s the object in the graph database also in my humble impression called nodes

  4. Why would we want to use a graph database instead of a normal SQL database?
    -Because in a normal database if you want to find the other common items in c’s table, you first need to find out which table c has a relationship to and then you can search for all the other items in that table. But in a graph database, you can see what tables c has a relationship with. And then you can follow the edges from that table to other vertices.

A graph database provides a strong advantage over relational database systems for certain datasets those that contain a large amount of relationships within the data. A Graph databases may not be the optimal choice for every business, but they have their advantages in certain situations.
