Reading Assignment: Graph databases. (answers)
Also known as a Vertex

What is a graph?
Graphs can be used to model data that contains objects and the relationships between them in the form of an abstract data type.
What is an edge?
Edges describe the relationships between the nodes of a graph. They link them together like a foreign key column would do in a relational database but more directly so.
What is a vertex?
Vertex is another name for a node. These entities/entries are the objects that can have properties associated with them. They are also the start and end points for edges within the graph structure.
When to use a graph database instead of a normal SQL database?
If your data has many and/or complex relationships between its stored objects you’ll get better performance out of it when your searches go more than one level deep.
What is a graph?
a graph is an abstract data type typically used to model data that contains objects
What is an edge?
An edge describes the relationship between objects.
What is a vertex?
A vertex is an object that has certain properties like things or people.
Why would we want to use a graph database instead of a normal SQL database?
Whenever there is a large number of relations in between the objects of a database
What is a graph?
An abstract data type used to model data that contains objects/nodes and some sort of relationship between objects/nodes.
What is an edge?
Describes the relationship between objects/nodes
What is a vertex?
The data object/node.
Why would we want to use a graph database instead of a normal SQL database?
Good for complex relationships on large amounts of data.
It’s an abstract data type in the form of nodes (containing data) and relationships between them.
These are relationships between nodes.
These are nodes
For complex relationships
1.) A Graph is a type of database which uses nodes or vertices to function as records in a relational manner. The nodes are connected by lines or edges which record the relationships between nodes.
2.) There are used to describe the relationship between the objects contained in the database. Comparable to a foreign key in a relational database.
3.) Vertices also known as nodes are connected to each other through “lines or edges”
4.) Directly stating relationships between two objects within a graph database provides a strong advantage over relational database systems for certain datasets. A Graph Database may also increase efficiency for searches like who performing a search that is more then one level deep.
a graph is a data type that is typically used to model data that contains objects and some sort of relationship between those objects
These are the foreign key’s for Graph databases
Vertex? or is it vertices? These are objects in the graph database.
With the more complicated relationships in a database it is better and faster to use a graph database
What is a graph?
A graph is a data type that is used to model data which contains objects and relationships of those objects
What is an edge?
Are like foreign keys which describe the relationship between objects
What is a vertex?
Objects or nodes in the graph
Why would we want to use a graph database instead of a normal SQL database?
When there are multiple queries required, Graph Database is more efficient
A abstract data type used to model data that contains objects and the relationships between them
the relationship between objects
Data that contains objects
A far greater ability to directly state the relationship(s) between two objects, namely when large amounts of data are concerned
A graph is an abstract data type which uses a model that contains nodes & verticals that shows a better relationship between each object.
A edge describes the relationship between each object in the database.
A vertex is another name for a node which represents the object filled with information.
Graph database would be better used when deeper relationships in the data need to be connected.
What is a graph?
A type of database that is based on nodes , (objects which are similar to rows in SQL) , properties (would be like columns in SQL) and edges (would be like foreign key in SQL) used for the relationship between different nodes.
What is an edge?
It is similar to a foreign key in SQL and its used to identify thatcher node and used for the relationship between different nodes.
What is a vertex?
an object or node that contains a unique item , similar to rows in SQL
Why would we want to use a graph database instead of a normal SQL database?
In complex scenarios where multiple searches should be performed on SQL , they are simpler on Graph since the he relations are directly between the objects or items , not between tables.
