AlertConfigurationRoleRecipient Table

This table is an extension of AlertConfiguration table that allows to register specific roles as recipients for a specific alert.

The structure of this table is:

Where:

• Id: unique id of this entry.
• AlertConfigurationId: the id of the Alert Configuration where this recipient belongs.
• RoleId:the id of the targeted Role.

TimeBasedAlertConfiguration Table

This table is an extension of AlertConfiguration that allows the configuration of alerts that are generated by a cron job instead of by the submission of a form. When the system starts-up, a Quartz job is created for each of the entries in this table. The job will be configured using the cron expression provided by this table and using the timezone of the facility where the associated Alert Configuration belongs to (given by the WorkspaceId column of AlertConfiguration).

The structure of this table is:

Where:

• Id: unique id of this configuration.
• AlertConfigurationId: the id of the Alert Configuration where this recipient belongs.
• CronExpression: the cron expression used to register a job in Quartz.
• FactName: This string is used by the time-based rules to know when they should be fired.
• JobKey: The Quartz job key associated with this entry. If this entry doesn't have a Quartz job associated, this value is null.

Alert Entries

Introduction

Whenever an alert rule is fired, one or more entries in the Alert table are inserted according to the configuration described in the previous section.

Alert Table

This table contains the specific data of an alert such as body, title, timestamp, etc. This table is the replacement of current 'alertticket' and 'alertstatus' tables. The patient/s associated to an alert are now placed in a separate table: AlertPatient.

The structure of this table is:

Where:

• Id: unique id of the alert.
• Timestamp: the creation timestamp.
• Title: the title of the alert.
• Description: the description of the alert.
• Payload: any payload (as text) that the alert has.
• Priority: the priority of the alert. Possible values are: High, Medium, Low. These values come from an enum defined in the application and not from another table.
• AlertConfigurationId: the id of the AlertConfiguration entry that generated this Alert. The associated AlertConfiguration can be used to retrieve information such as the recipients of the Alert (users or roles) and the rule that originated the Alert.
• Status: the status of the alert. Possible values are: New, Read, Archived. These values come from an enum defined in the application and not from another table.
• Source: A string identifying the source of this alert. This is free text that can be used to display purposes.
• UserId: the id of the user that generated this alert. In the case of time-based alerts, this value is NULL.

Alerts could be shared among different users. In this case, the status of the alert is also shared: when a user marks the alert as 'Read', the alert is now 'Read' for all the users sharing it.

AlertStatusAudit Table

This table serves as a log of how the status of an alert has changed in time.

The structure of this table is:

Where:

• Id: unique id of each entry.
• AlertId: the id of the alert this entry refers to.
• OldStatus: the old status of the alert (null when the alert is created).
• NewStatus: the new status of the alert.
• Timestamp: when the alert status was changed.
• UserId: who (userId) updated the status of the alert.

AlertPatient Table

This table contains the different patients an Alert is related to. 

Where:

• Id: unique id of each entry.
• AlertId: the id of the alert this entry refers to.
• PatientId: the patient related to the alert.
