The Old Nexus Logo
This was the original logo of the Nexus, but after partnering with Microsoft to build the next generation Query Tool they created the new logo for us (seen on the next page).

How to Customize your System Tree View
Introducing the new Nexus Super Join Builder
The Super Join Builder has 9 Tabs that are all there for your single query. Manipulate through the tabs and make changes to your query. The Super Join Builder does amazing things!
Define your Joins and tell Nexus to “Add and Remember Me”
Drag two tables inside Nexus and define the Join Columns. Click on “Add and Remember Join” and its in the Join Menu permanently. Check out the cool Join Menu on the next page.
Nexus knows what Tables Join together
How would you like to NEVER write another Join again? The Nexus makes that possible with the Nexus Super Join Builder. Just Right Click on a table and the menu tells you what other table(s) are eligible in the join. Then when you click on the next table Nexus writes the Join SQL automatically.
Nexus Presents Tables and their columns in Color
All Three tables we wish to join appear now with their columns and data types. Each table is a different color so when users utilize the other Tabs they see the columns in color to indicate which table there from. The Join SQL is already built, but we can use the other tabs to customize the SQL. The next picture will show the SQL already built!
Nexus Builds your SQL Automagically
By clicking on the SQL Tab you can see the SQL generated by the Nexus. All we did was click on the Objects Tab to select the tables and then we clicked on the columns we wanted on our report. In seconds the Nexus built this beautiful SQL.
Nexus can Cube a Table and Join to Everything Possible
When you click on the left side of a table in the Objects Tab and select CUBE the Nexus will create the SQL to join every table in the entire relationship together. Watch what happens on the next slide.
Nexus can Cube a Table and Join to Everything Possible
After hitting Cube with all Columns all tables in the relationship are joined.
The Cube SQL created Automagically
Manipulate the Columns with the Columns Tab
Rearrange the columns in the SELECT list by clicking and dragging. Control Click highlights multiple columns and Shift Click highlights an entire range of columns.
Single Click and ORDER BY using the Sort Tab
Double-Click or drag any column to sort by that column(s) in ASC or DESC mode.
Using the Joins Tab of Nexus
The Joins Tab shows all Join Conditions and allows you to change them to Outer Joins.
The SQL Tab reflects the changes we make in all other Tabs
This is the SQL generated after we changed our Join to a Right Outer Join in the Joins Tab and in the Sort Tab dragged columns Claim_Id and Street for our ORDER BY.
WHERE Tab shows Tables Indexes
The Answer Set Tab shows the Results
To get here we put the Sales_Table inside the Super Join Builder. Then we selected the columns we wanted and then went to the Analytics Tab. There we built our RANK report and pressed Execute. Then (above) we received the Answer Set.

The Metadata Tab shows Metadata
The Metadata tab allows a company to create Metadata for each table or object. This can be a word document, Power Point slide or whatever the company decides.
Nexus Makes a View look like a Table
Views in the Super Join Builder look like tables and can join to other views in a menu-driven fashion. Views looking like tables is brilliant and quite beneficial.
Nexus Joins Views to other Views in seconds
Views looking like tables is brilliant and quite beneficial. We can even join views to other views in seconds and pick the columns we want on our report.
Nexus can Cube a View and Join to all other related Views
When you click on the left side of a View in the Objects Tab and select CUBE the Nexus will create the SQL to join every View in the entire relationship together. Watch what happens on the next slide.
Nexus Cubes Views in Seconds
After hitting Cube with all Columns all Views in the relationship are joined.
The Cube SQL created on Views is done Automagically
Views with the Underlying Indexes of the Base Tables
We have just placed a view called Employee_V inside the Super Join Builder. We have selected all the columns. Now watch what happens when we go to the WHERE Tab.
WHERE Tab shows Views Underlying Base Table Indexes
After an Answer Set Returns you can do many things
After the Answer Set returns the Nexus allows you to manipulate the results further. You can perform OLAP calculations, Rank and many more.
After an Answer Set Returns Perform OLAP Calculations
We just performed OLAP on the answer set. Now the report comes (above in yellow), but what is amazing is that all calculations were performed internally by Nexus.
After an Answer Set Returns you can Graph and Chart
After the Answer Set returns the Nexus allows you to manipulate the results further. You can use Bisualize to Graph and Chart your answer set dynamically.

Saving an Answer Set in another Format
You can save an Answer Set directly to Excel or to many different formats.
