Reporting Database Schema

Introduction

This document covers the SQL-based reporting database schema.

The naming convention for table names and field names is an all-small snake case. Example: multiple_word_variable.

Records are updated in the following tables in the reporting database, as per the scheduled interval of all ETL jobs.
If any changes are done to the configurations, the previous report records are not updated and the new changes are applied to the new reporting data only.
This schema guide provides details about the reporting database tables which are used only for historical reporting. For real-time dashboards, the data is extracted through real-time REST APIs and available on real-time dashboards for supervisors.

Channels and Channel Sessions

channel_type

A channel type describes the type/class of the channels, for example, WHATSAPP, SMS, WEB. Multiple channels of a channel type can be created.

See more on Channel related terms

See Administrator Guide -> Add Channel Type for more details on Channel types.

Field	Constraints	Data type (MsSQL)	Data type (MySQL)	Description
channel_type_id	PK, NOT NULL	[nvarchar](50)	[varchar](50)	Unique id to identify this channel type
channel_type_name	NOT NULL	[nvarchar](50)	[varchar](50)	Records the name for this channel type, any alphanumeric value

channel

A channel instance is created when a new communication channel is registered by the admin. It includes all the configuration details of a channel, for example, the channel name, service identifier, channel mode, etc. A channel is of a particular channel type. For instance, we can create two channels WhatsApp-external and WhatsApp-internal, both of a channel type WHATSAPP.

channel_session

A customer can converse on multiple channels at a time in one conversation. A new channel session is created every time a customer initiates a session on a channel. For instance, a customer first opens up a chat from Webchat and later on, sends a message from its WhatsApp.

Key Reporting Concepts

Handled Conversation	A conversation is set to be "Handled" when the disposition of the last task in the conversation is set to CLOSED, with reason code DONE.
Abandoned Conversation	A conversation is considered as abandoned when the customer leaves while waiting in the queue or on ringing (agent alerting). In this case, the agent task in the conversation will be closed with the state CLOSED, with reason code CANCELLED.
Service Level Agreement % (SLA%)	Service level measures the percentage of incoming conversations that an agent answers within the specified Service Level (SL) threshold defined in the queue configurations. The service level threshold timer starts as soon as the conversation is queued to a precision queue. The service level threshold is the number of seconds you set as a goal for connecting a conversation with an agent. For example, your goal might be to answer 80% of conversations within two minutes. In this case, you would set the service level threshold to 120 seconds. Reports show you the percentage of conversations that are answered within that time threshold, enabling you to see whether you are meeting your goal.
AnsweredWithinSL	When a conversation is queued and accepted by agent within SL threshold, it is said to be answered within the Service Level.
AnsweredAfterSL	When a conversation is queued and accepted by agent after SL threshold, it is said to be answered after the Service Level.
AbandonedWithinSL	When a conversation is queued and gets abandoned within SL threshold,, it is said to be abandoned within the Service Level.
AbandonedAfterSL	When a conversation is queued and gets abandoned after SL threshold,, it is said to be abandoned after the Service Level.
OfferedWithinSL	The sum of AnsweredWithinSL and AbandonedWithinSL is said to be offered within SL.
Service Level calculations	The calculations for service level are based on the Service Level Type defined in the queue configuration. There are three possible Service Level Types: 1 - Ignore Abandoned Conversations : AnsweredWithinSL / (TotalOffered – AbandonedWithinSL) 2 - Abandoned Conversations have Negative Impact : AnsweredWithinSL / (TotalOffered) 3 - Abandoned Conversations have Positive Impact : (AnsweredWithinSL + AbandonedWithinSL) / TotalOffered

Note :
Consult SLA Calculations for further details.
