# Overview

This document is intended as an overview of New XINA, with basic things you should know.

# New Terminology

Some XINA terms have changed, to be more accurate or to better support a variety of missions.

| New XINA | Definition | Related Old XINA Terms |
|-|-|-|
| **Mnemonic** | a named data channel or field | *hk*, *housekeeping*, or *housekeeping field* |
| **Event** | a time with a label; might be an *Instant*, which is just one moment in time, or it might be an *Interval*, with a start and end. | a category that includes *TIDs*, *markers*, *messages*, *alerts*, *spectra*, and more |
| **Spectrum** | a multi-dimensional data set associated with a single time or time range | a category that includes *scans* |
| **Nominal Range** | a green, yellow, or red value range for a particular mnemonic | a category that includes *limits*, *expected values*, and more |
| **Notebook** | a digital lab journal | *journal* |

# Tools

XINA tools are now divided into three broad categories.

## Visualization
Visualization tools are primarily focused on looking at data within XINA, like charts and tables. Most of them also support some sort of data export.

- The **Mnemonic Plot** and **Mnemonic Trending** tools plot mnemonic data; the former against a single time range and the latter against many.
- The **Events** tool centers around a table of events and can group them in arbitrary ways.
- The **Spectra Viewer** is what you need for science data, and gives many options for presentation and organization.
- The **Nominal Range Trending** tool is a new option for instrument health reports, using a table that checks mnemonics against nominal ranges at specified intervals.
- The **Diagram Viewer** and **Diagram Simulator** animate custom dashboards and diagrams with mnemonic and event data. The *Viewer* uses real data, and the *Simulator* is designed around simple human-readable "sequence files".

## Exporting
Export tools are built around downloadable data sets and reports. While other tools may support exporting data, these tools are *only* for exporting.

- The **Mnemonic Export** and **Mnemonic Trend Export** tools allow you to perform or automate high-volume data exports. They're ideal when you want to look at months of data at a time.
- The **Packages** tool is the best way to browse existing export products.

## Management
Management tools are designed for advanced users to control XINA data and operations.

- The **Mnemonic Management** tool is for managing mnemonics, particularly correcting issues with definitions and aliases.
- The **Model Management** tool helps with managing mining processes and scheduled tasks.
- The **Nominal Range Management** tool is for managing nominal ranges. It also supports exporting the definitions in various formats.
- The **Diagram Editor** allows you to set up the diagrams used by the *Diagram Viewer* and *Simulator*.
