Trillion-Row Spreadsheet
The Trillion-Row Spreadsheet (TRS) allows you to visually interact with your data.
- Analyze
  The Analyze tab displays the object browser and the Analysis Timeline.
  - Object browser
    The object browser provides a hierarchy of folders and objects to which you have access. Use the object browser to select the base table or query for your analysis.
  - Analysis Timeline
    The Analysis Timeline displays a visual representation of your data analysis in the Trillion-Row Spreadsheet.
  - Selecting rows
    Selecting rows is one of the most basic tasks in the 1010data Insights Platform. Use row selection to isolate data that is important to your analysis and create more efficient queries.
    - Select rows panel
      The Select rows panel allows you to specify the selection criteria using the simple comparisons options or enter a selection expression in the Expression Editor.
    - Simple comparisons relationship options
      When performing a simple comparison in the Select rows panel, the relationship options define the association between a column and a value in the resulting selection expression.
    - Use simple comparisons to select rows
      Row selection allows you to focus on a subset of rows.
    - Select rows by entering a selection expression
      You can define a subset of rows using a selection expression, a mathematical formula that evaluates to 1 (true) or 0 (false).
    - Performing a Quick selection using the grid
      Use the grid to perform a Quick selection in a table or worksheet.
  - Sorting rows
    You may reorder the rows of a table such that the values in a particular column are in ascending or descending order.
  - Arranging columns
    You can display a subset of the columns in a table and specify the order in which they appear.
  - Linking tables and worksheets
    Use linking to combine tables or worksheets into a single, bigger table with columns from both.
  - Computed column
    A computed column is a column that you add to a table, whose values are typically based on one or more existing columns.
  - Summarizations and tabulations
    Some of the basic ways to analyze your data include quick summaries, tabulations, and cross tabulations.
  - Merging tables and worksheets
    You can merge two or more tables or worksheets to combine their rows together into a single, larger worksheet.
  - Amending values
    Replace the values in a table or worksheet using the amend operation.
  - Running custom code
    You can run custom SQL, Python, R, or K3 code within the TRS Analysis Timeline.
  - Miscellaneous operations
    In addition to the five basic operations, you can choose to use a miscellaneous operation in the Trillion-Row Spreadsheet.
- Query
  The Query tab displays the current timeline query as Macro Language XML code. It also provides the ability to undo and redo operations in the timeline.
- View
  Select among the ways to view and interact with the data resulting from your analysis.
- Visualize
  The 1010data Insights Platform provides a mechanism to generate high-quality charts, which in turn can support the notion of visual data discovery.
- Develop
  Use the query that represents your analysis as a base for further development.
- Export
  Export the data resulting from your analysis to various destinations.
- Results pane
  The results pane is displayed on the right side of the Trillion-Row Spreadsheet window and Macro Language Workshop.

Selecting rows

Selecting rows is one of the most basic tasks in the 1010data Insights Platform. Use row selection to isolate data that is important to your analysis and create more efficient queries.

Whether you are working with a table that is very small or very large, the first step to answering an analytical question is to narrow down the data you are working with so you see only the pieces of information that apply. While there are many ways to do this, the most basic is a row selection.

When you work with very large data sets like those typically found in the Insights Platform, the order in which you perform operations on the data makes a difference in how fast the system can complete those operations. If you make the largest selection that eliminates the most data first, then the subsequent operations you perform finish faster because the platform does not need to work with as much information. As a best practice, if your data contains columns with date- or time-related information, that is generally the best place to start. However, the largest selection may be something other than date or time information and is based on your data and the analysis you want to perform.

If you perform several row selections in succession, each selection is applied to the previously selected rows. With each selection, the number of rows will decrease (or possibly stay the same); it will never increase. The Analysis Timeline displays every selection applied to the table or worksheet and the number of rows remaining after these selections are listed at the top of the grid. Only those rows that meet your criteria are displayed. Also, if you summarize the data, only the selected rows will be included in the summary.

Note: The selection applies only to your current workspace and does not affect the original table.

There are several ways to perform a row selection in the Trillion-Row Spreadsheet. You can specify the selection criteria using the Simple Comparisons options, enter a selection expression in the Expression Editor, or select rows within the grid itself.
