The following are the types of NoSQL database in use [48]. 1. Graph stores are used to store information about networks of data, such as social connections. Graph stores include Neo4j and triple stores like Fuseki.
Which data structure is used for finding mutual friends in social media websites?
Facebook uses the Graph data structure to maintain relationship between friends. In fb each user is considered as a vertex and if an edge connects two users(vertices) then those two users are considered as friends. The concept of mutual friends is mainly finding the strongly connected components in a graph.
How do you decide which data structure to use?
When selecting a data structure to solve a problem, you should follow these steps.
- Analyze your problem to determine the basic operations that must be supported.
- Quantify the resource constraints for each operation.
- Select the data structure that best meets these requirements.
What is social network analysis is used for collecting the dataset?
Social network analysis (SNA), also known as network science, is a field of data analytics that uses networks and graph theory to understand social structures. SNA techniques can also be applied to networks outside of the societal realm.
The most common database designs for social networking sites include quick reference functions, features for the addition and removal of social media sites and channels to your own database and the ability to filter sites based on multiple features. Almost 3 billion people use social networking sites regularly.
What is social network structure?
A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors.
For instance, our study reveals that three network layers—cell phone communications, questionnaires about friendship, and trust relations—lead to similar and consistent results despite some minor discrepancies.
What makes a good database for a social networking website?
A good database for a social networking website should support read-scaling, write-scaling, use of lock-free data structures and algorithms. There are certain types of faults that your database will not be able to handle when they occur and there are others it can.
Three dimensions of social network structure dominate in the literature. The first is network density, the number of existing relationships relative to the possible number. Dense networks are more important for control and sanctioning than for information. Dense networks tend to generate a lot of redundant information.
What determines the effectiveness of social network structures?
Again depending on the instrumental value of the social network under investigation, certain network structures are more effective than others. Three dimensions of social network structure dominate in the literature. The first is network density, the number of existing relationships relative to the possible number.
Consider a special social network where people are called connected if one person is connected to other with any number of intermediate connections. For example if a person x is connected with y and y is connected with z, then x is also considered to be connected with z. We are given a set of friend requests as input.
