ETL Tool – Informatica – Part 2
Informatica Power Exchange as a stand alone service or along with Power Center, helps organizations leverage data by avoiding manual coding of data extraction programs. Power Exchange supports batch, real time and changed data capture options in main frame (DB2, VSAM, IMS etc.), mid range (AS400 DB2 etc.,), and for relational databases (oracle, sql server, db2 etc) and flat files in unix, linux and windows systems.
This helps to transfer large amount of encrypted and compressed data over LAN, WAN, through Firewalls, transfer files over FTP, etc.
Meta Data Exchange:
Metadata Exchange enables organizations to take advantage of the time and effort already invested in defining data structures within their IT environment when used with Power Center. For example, an organization may be using data modeling tools, such as Erwin, Embarcadero, Oracle designer, Sybase Power Designer etc for developing data
models. Functional and technical team should have spent much time and effort in creating the data model’s data structures(tables, columns, data types, procedures, functions, triggers etc). By using meta data exchange, these data structures can be imported into power center to identify source and target mappings which leverages time and effort. There is no need for Informatica developer to create these data structures once again.
Power Analyzer provides organizations with reporting facilities. PowerAnalyzer makes accessing, analyzing, and sharing enterprise data simple and easily available to decision makers. PowerAnalyzer enables to gain insight into business processes and develop business intelligence.
With PowerAnalyzer, an organization can extract, filter, format, and analyze corporate information from data stored in a data warehouse, data mart, operational data
store, or other data storage models. PowerAnalyzer is best with a dimensional data warehouse in a relational database. It can also run reports on data in any
table in a relational database that do not conform to the dimensional model.
Superglue is used for loading metadata in a centralized place from several sources. Reports can be run against this superglue to analyze meta data.
Power Mart is a departmental version of Informatica for building, deploying, and managing data warehouses and data marts. Power center is used for corporate enterprise data warehouse and power mart is used for departmental data warehouses like data marts. Power Center supports global repositories and networked repositories and it can be connected to several sources. Power Mart supports single repository and it can be connected to fewer sources when compared to Power Center. Power Mart can extensible grow to an enterprise implementation and it is easy for developer productivity through a code-less environment.
