Go through this tutorial to gain hands-on ETL knowledge.

What is Informatica Cloud?

Informatica is an American software development company founded in 1993 and headquartered in Redwood City, California. Informatica is also known as Informatica power centre. It uses the extraction, transformation and loading (ETL) tool, which is widely used in building an enterprise data warehouse.

Informatica launched its Informatica integrated cloud services (IICS) in 2017. The main goal is to accelerate data that drive digital transformation in businesses. Informatica power centre's data integration connects and retrieves data from different sources and processes them. The PowerCenter server accomplishes tasks on a workflow that workflow managers create, and the workflow monitor in the power centre monitors the workflows. Informatica's IICS has a massive demand for data integration and management platforms which work similarly to Software as a Service (SaaS). Informatica has helped more than 9000 customers. Many clients like Allianz, Fannie Mae, ING, and Samsung use Informatica's power career centre as their data integration system.

Difference between Informatica and Informatica Cloud?

Informatica Cloud provides almost all the abilities that Informatica PowerCenter offers. Additionally, Informatica Cloud provides Cloud Designer. 

  • It provides more advanced data integration capabilities than the PowerCenter Designer 
  • We do not have to connect all the ports manually as we do in PowerCenter
  • We can also create reusable mappings using parameterized values

Informatica Cloud Architecture

Informatica architecture is a type of Service-oriented Architecture (SOA). Service-oriented architecture is a group service where one can communicate with each other, and it simplifies data transfer during this communication.Informatica ArchitectureInformatica ETL tool has the below services and components, such as:

  • Informatica domain: it is an administrative unit which contains nodes and services. These are further divided into folders and subfolders.
  • Repository service: The clients and the PowerCenter repositories are connected by Repository services. It is a multi-threaded process. It integrates the metadata and provides access to other services also.
  • Integration service: it integrates the movement of data from targets to sources.
  • Reporting services: these handle metadata and allow other services to access the same.
  • Repository manager: manages objects in the repository.
  • A workflow manager is needed to create workflows and tasks and execute them.
  • Mapping designer: it helps create metadata of mappings and store them in the IICS repository.
  • Source and Target: The source and target of metadata include data type, precision, scale, and other information about the source and target objects stored in the IICS repository.

Components of Informatica Cloud

Components are resources which assist in mapping and tasks; there are many components in the Informatica cloud.

API collections

An API collection gives the following mappings schemas

Request schema used to map incoming fields in transformation

Response schema is used to map response fields from the Rest API

Fixed-width file formats

one can create and save multiple fixed-width file formats that specify the formatting details for fixed-width flat files. It can be used as a source or target in mappings and mapping tasks.

Business services

A business service is a web service which includes configured operations.

Hierarchical schemas

A hierarchical schema is considered an asset which is based on a schema file or sample JSON file, XML sample file or XML schema that is imported into Data Integration.

File listeners

A file listener listens to a particular folder and the file patterns. Some events trigger a notification in the below assets.

  • Task flows
  • File ingestion tasks
  • B2B gateway partners
Intelligent structure models

Intelligent structure creates a model which articulates the expected output data. An intelligent structure model is used in mappings to analyse structured, semi-structured or unstructured data. Users can create multiple formats by using

  • JSON files
  • Avro files
  • Parquet files
  • XML FILES
  • ORC files
  • Microsoft Excel files etc
User-defined functions

using the Informatica Intelligent Cloud Services transformation language, one can create user-defined functions. User-defined functions are reusable functions that you can use in expressions.

Connectors provided by Informatica Cloud

Many pre-installed connectors are available in Informatica the cloud, and in addition to them, one can create new connections for any connector installed in Informatica, the intelligent cloud service. One needs connectors in creating connections. Connections are provided to access features like data in cloud and on-premise applications, flat files,database and platforms.

OData connector: 

OData connector is known as Open Data Protocol (OData) which is a standard version of OASIS with best practices to build and consume RESTful APIs. With OData, one can customise their needs and develop RESTful APIs.

Web service consumer connector:

Web service applications that support SOAP API are connected to consumers by a web service consumer connector. Web service consumer connector is used in web services for transforming data.

REST V2 Connector:

REST V2 Connector is used to interact with web service applications that are built on REST architecture. REST V2 Connector can also be used in other areas like Source transformation, Target transformation, or midstream in a Web Services transformation. REST V2 Connector is used to midstream a mapping to pass one or many requests to a web service application and process the response data.

JSON Target Connector:

With the help of a JSON template, the JSON target connector converts source data into JSON format. In synchronisation tasks, JSON Target Connectors objects as targets.
