Cloud Computing and IBM InfoSphere Information Serve

Cloud computing is the next evolution in IT computing models following the time-tested centralized mainframe model, and the more recent client-server model. It has emerged to address the demand for reduced IT complexity, rapid deployment and consumption-based pricing models. By leveraging on-demand virtualized and dynamic IT infrastructure, cloud computing can help to transform multiple IT projects including accelerating core system renewal or outsourcing projects or business analytics and optimization investments. Whether an organization’s information-led IT transformation is on-premise, or in the cloud, or a mixture of the two, the lack of trusted information can interfere with an organization’s ability to act with speed, agility and success.

Data transformation and movement is the process by which source data is selected, converted, and mapped to the format required by targeted systems. The process manipulates data to bring it into compliance with business, domain, and integrity rules and with other data in the target environment. Transformation can take some of the following forms:

  • Aggregation Consolidating or summarizing data values into a single value. Collecting daily sales data to be aggregated to the weekly level is a common example of aggregation.
  • Basic conversion Ensuring that data types are correctly converted and mapped from source to target columns.
  • Cleansing Resolving inconsistencies and fixing the anomalies in source data.
  • Derivation Transforming data from multiple sources by using a complex business rule or algorithm.
  • Enrichment Combining data from internal or external sources to provide additional meaning to the data. Normalizing Reducing the amount of redundant and potentially duplicated data.
  • Combining The process of combining data from multiple sources via parallel Lookup, Join, or Merge operations.
  • Pivoting Converting records in an input stream to many records in the appropriate table in the data warehouse or data mart.
  • Sorting Grouping related records and sequencing data based on data or string values

In its simplest form, IBM InfoSphere DataStage performs data transformation and movement from source systems to target systems in batch and in real time. The data sources might include indexed files, sequential files, relational databases, archives, external data sources, enterprise applications, and message queues.

DataStage manages data that arrives and data that is received on a periodic or scheduled basis. It enables companies to solve large-scale business problems with high-performance processing of massive data volumes. By leveraging the parallel processing capabilities of multiprocessor hardware platforms, DataStage can scale to satisfy the demands of ever-growing data volumes, stringent real-time requirements, and ever-shrinking batch windows.

Leveraging the combined suite of IBM Information Server, DataStage can simplify the development of authoritative master data by showing where and how information is stored across source systems. DataStage can also consolidate disparate data into a single, reliable record, cleanses and standardizes information, removes duplicates, and links records together across systems. This master record can be loaded into operational data stores, data warehouses, or master data applications such as IBM MDM using IBM InfoSphere DataStage.

IBM InfoSphere DataStage delivers four core capabilities:

  • Connectivity to a wide range of mainframe, legacy, and enterprise applications, databases, file formats, and external information sources.
  • Prebuilt library of more than 300 functions including data validation rules and very complex transformations
  • Maximum throughput using a parallel, high-performance processing architecture
  • Enterprise-class capabilities for development, deployment, maintenance, and high-availability. It leverages metadata for analysis and maintenance. It also operates in batch, real time, or as a Web service.

In the following sections, we briefly describe the following aspects of IBM InfoSphere DataStage:

  • Data transformation
  • Jobs
  • Parallel processing

Ans. MOLAP tools utilize a pre-calculated data set, commonly referred to as a data cube and MOLAP systems gives fast response. MOLAP systems are generally used for bounded problem set. ROLAP tools are best used for users who have “unbounded” problem set .

ROLAP tools do not use pre-calculated data cubes. Instead, queries the standard relational database and its tables in order to  answer the question and ROLAP systems are comparatively slow.

Hybrid OLAP systems can use capability of both pre-calculated cubes and relational data sources. 

Data in the data mart is refreshed in accordance with the predetermined frequency schedule established by the Project Manager. Within BusinessObjects, a document generated at a given point in time reflects the data as it existed at that time and may be inaccurate now. When you update a document, B O reconnects to the database and retrieves the updated data. This is called refreshing a document.

B O lets you update the data in a document while keeping the same presentation and formatting, either:

  1. manually
  2. automatically at specified times or intervals
  3. by sending the documents to Broadcast Agent, the B O product that manages scheduled processing of documents

every time you open a document.
