Link Analysis Overview
Free TrialWith Microsoft SQL Server, Sentinel Visualizer supports millions of entity and relationship records. Send all your data to the diagram or use search features like the Dataset Builder and Advanced Dataset Builder to select a subset of data for your link chart. Pick entities and relationships by their specific characteristics and links to each other. You can start big and drill down to details, or expand from individual entities one degree at a time until you include their entire network. Thousands of data points can be added to your diagram in a highly optimized, scalable, and shareable manner.

Once your data is on the Visualizer Diagram, a wide range of tools are available to customize and perform additional analysis. Here are some of the options on the panels:
Entity Options
The Entities Panel customizes how the entities are displayed. Filter the selections, show and hide entities based on their links, show labels, filter the entities by value ranges and perform additional refinements.
Relationship Options
The Relationships Panel customizes how the relationships are displayed. Customize the lines with labels, sums, arrows, and whether they should be angled or straight. Filter the relationships by value ranges and perform additional refinements.
Gradient Options
Color and resize Entities and Relationship Lines based on different numeric metrics to highlight the data you're seeking. Metadata can also be used to color Entities.
Link Options, Shortest Path
Discover interesting connections by selecting two entities for the Shortest Path and All Paths between them, then filter the diagram to just those entitles. Additional options to view and filter cutpoints, separate disconnected networks, and cliques within a network.
Add Shapes to the Visualizer Diagram
Add Text, boxes, lines and arrows to your diagram.
Options to set their size, colors and styles.
Add Items to the Visualizer Diagram
Visually add new entities and relationships to the diagram by clicking and dragging.
Use it for temporary illustration or save it to your database permanently.
Navigator to the Visualizer Diagram
Easily select a portion of your complex network to expand in the Diagram.
Drag the box in the navigator panel to see it in the Diagram.
Save, Share and Merge Diagrams
You can save your diagrams into the database to retrieve them in the future. They can be shared with other authorized users or kept private to yourself. You can also merge saved diagrams into your current diagram to combine multiple sets of analysis.
Rather than dumping all the data and finding the relationships, you can start with one entity and build from there. Use the Get Links feature to add to its network. You can expand it by the number of degrees (its links, the links of its links, etc.). When links are added the links among the entities are also displayed. You can also use the Entire Network feature to load all the connections related to the entity no matter how many degrees away they are.
Start with One Entity
Get Links One Degree
Notice two of the entities are also connected to each other
Get Links Two Degrees
Get Links Entire Network
The Between Selected feature lets you select multiple entities to add the fewest entities connecting them. Discover the smallest, tightest network among them.
For example, for Contact Tracing, three students tested positive. Between Selected quickly identifies the shortest path between them.

Combined with Data Refinement
Data Refinement lets you filter the type of Entities and Relationships on your diagram.
When data refinement is applied, Get Links respects those settings and only retrieves the entities and relationships that pass the filters. Easily focus on the data you want while excluding irrelevant data.
Sentinel Visualizer lets you apply advanced Link Analysis visualization to reveal the hidden relationships in your data. Leveraging your definitions of entities and relationships among them, turn rows and columns into visual data revealing multi-level hierarchical relationships. Quickly understand hidden links among people, places and events that are nearly impossible to see in traditional data grids.

As entities are placed on the network and their links added, you can easily see the entities they have in common. This helps you focus your limited time and budget on the most suspicious and highest value targets.

Sentinel Visualizer includes the ability to view your complex link chart in three dimensions. Fly through your relationships and/or animate them to see the links in an even more powerful way.
