Information protection is one of the common entry points for organizations getting started with information governance. Protecting sensitive data serves a clear business need, and protecting data is the goal of many current regulations. In this 2 part series we will start looking at the protection of data in this article by looking at the security of IBM Data Servers on z/OS. This will be followed by part 2 looking at audit and compliance.

Feeding a data warehouse with changes from the source database can be
very expensive. If the extraction is only done with SQL, there is no way to
easily identify the rows that have been changed. IBM InfoSphere Replication
Server can detect changed data by reading only the database log. This article
series illustrates how you can use InfoSphere Replication Server to
efficiently extract just the changed data, and then pass the changes to IBM
InfoSphere DataStage to feed the data warehouse. This is a two-part article
series. In Part 1, get an overview of the products and how they can work
together. In Part 2, explore two different integration options: with staging
tables or with MQ messages.

The concept of shell sharing between
Eclipse-based products means that you can share the core Eclipse components so that they are not duplicated between each
Eclipse-based product. Shell sharing can save disk space, eliminate duplication of components, and enable products to interact
with each other,
making each product stronger than if it were run stand-alone. This article explains the process of sharing Eclipse shells between
many different IBM products by showing an example of this using InfoSphere Data Architect (IDA),
Optim Development Studio (ODS) and Optim Database Administrator (ODA).

IBM Informix 4GL is a comprehensive development and production environment for creating sophisticated database
applications.
The 7.50.xC4 release of Informix 4GL includes direct support for file I/O without requiring function calls in
another language such as C.
This article describes the advantages of using the direct I/O support and provides you with an introduction
to how you can use it with operations such as OPEN FILE, CLOSE FILE, READ, WRITE, and SEEK.
The article includes code samples that can
help you get started with implementing the file I/O feature in your own applications.

The IBM Enterprise Content Management Widgets (ECM Widgets) product is
gaining traction in banking, insurance, health care, and many other fields.
The ease of use and programming-free nature of the widgets enable business
application developers to quickly produce content management applications. For
industry solutions that require customized widgets, developers can build new
widgets to meet their own business requirements. These customized widgets can
be easily integrated into the ECM widgets environment by events wiring. In
this article series, learn how to develop custom widgets to integrate them
with four ECM widgets to build powerful solutions. Part 1 details how to use
events of the In-basket widget and how to develop a role selector widget to
work with the In-basket widget.

This article gives an end-to-end example of how an Open SQL query that
handles arbitrary JOINS between SAP tables that are not known during coding
time can be executed dynamically. You will learn how joins are done in Open
SQL, how to specify the needed clauses of this statement during runtime, and
how to dynamically create the target structure that is needed with the help of
the RTTS (Run Time Type Services) API of ABAP. Specifying Open SQL conditions
with joins during execution time has many applications, including when the
queries are only known during runtime. Data extraction and data browsing of
the SAP system are examples. In another example, specifying queries
dynamically helps if the main application logic is not implemented in ABAP
code but in a remote program. In this case, this article describes how only a
small generic ABAP program is needed, and the SQL queries can be maintained
externally.

pureQuery improves application throughput on DB2(R) for z/OS(R) by making it easy to deploy static SQL for Java(TM) for any
new or existing application. For new applications, this can be accomplished by using the pureQuery DAO interfaces and annotated methods.
The client optimization feature enables capture and bind of SQL in any Java application, including those using a framework.
This article has been updated with the latest performance numbers from the Version 2.2 release of the Optim(TM) pureQuery Runtime.

Predictive analytics software helps you to find non-obvious, hidden patterns in large
data sets.
Current tools for predictive analytics, such as SPSS (an IBM company) and IBM InfoSphere Warehouse, expect data to be represented in an
appropriate way before the actual analysis can take place.
However, you may have cases where the data you want to analyze is not readily available in
a format these tools can recognize.
For example, SAP systems are widely used by many companies across a variety of industries, but
data in SAP systems is not directly accessible to these tools.
This article shows you how to use IBM InfoSphere Information Server to extract data from SAP systems for analysis
within InfoSphere Warehouse and SPSS PASW Modeler.

The Rapid Deployment Package (RDP) for IBM InfoSphere Master Data
Management Server solution addresses the needs of clients in the first phase
of implementing initial load solutions.
Using MDM, clients need to perform
initial and delta loads, typically as a batch.
This article focuses on the
RDP Direct Load approach using Information Server 8.0.1 to perform the
initial data load for an MDM server solution running InfoSphere MDM Server
Version 8.0.1.
In addition to the introduction, installation, and setup for this approach, the article also
provides performance tuning tips and best practices.
You can use the
recommendations provided in this article as guidance while developing your own MDM Server initial
load solutions using the RDP Direct Load approach.

In this article, learn how you can use a user exit to extend Optim
Performance Manager to integrate DB2 for Linux, UNIX, and Windows database
monitoring with enterprise monitoring systems, using the Simple Network
Management Protocol (SNMP) for system and network monitoring. The user exit is
a simple general purpose mechanism that can be configured to call any
executable program making it possible for you to use DB2 database performance
alerts in a wide variety of ways.

Before you can implement any information-centric project like archiving,
data privacy, master data management (MDM), data warehousing, data lineage, or
application data consolidation, you have to know what data you have, where it
is located, and how it is related between systems. For most organizations, the
data discovery and analysis process is very manual, requiring months of human
involvement to discover business objects, sensitive data, cross-source data
relationships, and transformation logic. In this article, learn how IBM
InfoSphere Discovery provides sophisticated analysis to automate the analysis
process and generate actionable results.
