Explain about ServiceNow Integration?

                                  

Integration is an exchange of information between company applications and ServiceNow instance. We can establish integrations before or after the ServiceNow implementation goes live. However, the best practice is to enable the implementation before it goes live. Enabling integration before implementation allows you to test the integration. This is especially important for integration to the user lists or single sign-on applications. Service now integrates with a variety of third-party applications and data sources. It usually integrates with problem management, Integration management, CMDB, User administration. For this integration, it uses the variety of techniques like JDBC, Email, Excel, CSV, Web Services, SOAP, WDSL (OR) REST. A ServiceNow implementation connects from a single machine using a fixed IP address through the specific port on your firewall. This allows the firewall to limit the traffic to the particular IP address.

Integration technologies:

Servicenow the platform is based on the Service-oriented architecture in which all data objects uses web services to access bi-directional data integration. The interface is dynamic and direct in which all modifications to the existing objects and for all the new objects were automatically published as a web service as a Direct Web Service.  The Mapped web service uses indirect web service creation in which transform map is used to gather the incoming web service data into final targeted tables.For irrelevant data, an advanced Scripted Web service is available for defining process-based services.

Additionally, this platform offers a rich interface for loading external data using import sets. The major advantage of this feature is you can load data from various data sources such as HTTPS, FTPS, and SCP from various formats like XML, CSV and XLS files.Information can be pulled from a data source using JDBC connection.Data can be pulled from one platform another using ODBC Driver. Advanced Scripted web service is available. Advanced scripted web service techniques are available for defining process based web services where data is irrelevant which serves as a processor composite of actions that execute the server.

Integration between ServiceNow Instances:

There are some situations where you need to perform a specific integration between your instance and other ServiceNow instance. Instance – to – Instance integrations are a snap because all integration points exist between those two instances.

Login: ServiceNow supports a user logging feature.Its techniques include single sign-on, Loading users as well as dynamic user record creation, groups and location data.

User Data: Dynamic User accounts can be created using ServiceNow by importing active directory or Open LDAP implementation. You can do this securely through point – to point VPN. Moreover, we can use dynamic mapping of data sources such as such as files or databases through JDBC for importing groups, data into ServiceNow using import sets.

Data and Process: Data and process integration can be categorized as event-based or batch load

An event-based integration creates records for the purpose of triggering additional workflow of the system more on demand and usually with a smaller payload. It records usually go through an a\external queuing table called ECC Queue.

 Batch or load based integration is usually done with a scheduled import set where mapping and script can be defined to gather data from various data sources into the system and transform them into the records in tables.

User Interface integration: Integration at user Interface level allows standard exposure of knowledge-based articles into websites seamless embedding of service now charts and reports into portals, embedding of in context  URL’s into other web-enabled applications.

Advantages:

ServiceNow has various benefits by integrating ServiceNow with third-party applications.

Below are options of ServiceNow for integrating with third-party applications:

We can build our own custom integration using platform integration interfaces.

Users can install integration from a share

Users can install a certified integration from the ServiceNow store

Users can activate ServiceNow provided integration.

Brief Introduction About Servicenow Data Management Structure?

        Data in servicenow is instance and it is stored and managed by a principled structure that can be view and configured by the Administrator.  Data administration functions include importing, exporting, and archiving database data and configuring fields and tables. To effectively manage and improve your systems, you have to know exactly what resources are in your IT condition and have present exact configuration data. With an exact configuration management database (CMDB), it’s easy to understand your association’s IT environment, especially in the areas of service impact analysis, resource management, compliance, and configuration management.

The ServiceNow CMDB gives a single system of record for IT. At the point when combined with ServiceNow Service Mapping, the CMDB becomes service aware which empowers your ServiceNow applications to be service aware too. Presently with your CMDB, you increase the full visibility of your infrastructure and service, leading to more control of your environment and better choices.

Below are some important features of Data management

The information is stored in database tables and records.

Different tools exist to deal with this data.

The schema map displays CI relations graphically.

Data word reference tables store structure and relationship definitions.

Data import and export simplifies managing large data sets through import maps and various exportable formats.

Different modules give extra functionality.

Field standardization makes records more reliable and prevents duplication of data.

Database structure:

The majority of the data in the instances is stored in tables, which consists of a series of records. The record thus holds a series of fields that hold the individual bits of information and can be viewed either as a list or a form.

Read more about ServiceNow in this overview ServiceNow Online Training.

The table can be related to each other in many ways:

Extensions:  A table can extend another table. The table expanding incorporates the majority of the fields of the other table (parent class) and includes its own fields. For example, the Incident [incident] table has the majority of the Task [task] table fields (on the grounds that an occurrence is an exceptional type of errand) and has its own incident specific tasks.

One – to – Many: A field can hold a reference to a record in another table within a table.

There are three types of one-to-many relationship fields.

Reference Field: It enables a user to choose a record on a table defined by the reference field. For example, the Caller field on the Incident table enables the user to choose any record on the User table.

Glide List:  It enables a client to choose different records on a table characterized by the glide list. For example, the Watchlist field on the Incident table enables the client to choose records on the User table.

 Document ID Field: enables a user to choose a record on any table in the table. These fields are substantially less common, yet one example is the Document field on the Translated Text [sys_translated_text] table.

Many- to – Many: Two tables can have a bi-directional relationship, with the goal that the related records are visible from the two tables in a related list.

Database Views: Two tables can be joined for all purposes with Database Views to enable reporting on data that may be put away stored over more than one table.

Data management Tools:

 There is the number of data a management tool that helps to manage the data.

Schema map: The Schema Map shows the connections between tables visually, exploring through the database structure. The Schema Map gives an interface to review the connections between tables. The inter-table connections it captures incorporate many-to-many relationships,  tables that extend other tables, and tables that reference other tables through reference fields.

Data Dictionary Tables: Data dictionary tables hold data that characterizes the database and can accesses data on the database schema.

Table Cleaner: The system automatically records from particular tables after a particular time to deletion. Erasing these records naturally, keeps the tables from developing to an unmanageable size. The time before a record is deleted starts on the date and time value in the tracked field.
