Technology - Why Unit Testing is Important

Why Unit Testing is Important

Unit testing enables developers to detect and resolve defects early in the software development process. This saves costs as it reduces the time and effort required for debugging, and makes the code more reliable, scalable and maintainable. It also enables developers to change parts of the system without fear that they may break other parts of the application. This enables frequent and agile releases of software applications. Reliability Reliability is arguably one of the most important aspects of software development. The more reliable the program, the fewer errors users will encounter and the faster it can be repaired when an …

Enterprises and cloud computing become more integrated and essential for gaining or maintaining a competitive advantage through big data and Analytics. Cloud is now essential in improving operations efficiency and synergy. To optimize the enterprise architecture with the cloud, there are a few strategic questions that need to be considered; First, how much cloud business does your enterprise need? And, what cloud strategy best meets your enterprise operational and security needs? Where do private, public clouds, or hybrid cloud fit in your enterprise’s information workload deployment strategy? Does multi-cloud fit in the enterprise’s information workload deployment strategy? What is A …

Technology - What Are "Blue-Green" Or "Red-Black" Deployments?

Technology – What Are “Blue-Green” Or “Red-Black” Deployments?

Chances are you’ve participated in changing or upgrading software or application. While the idea is to push new features to customers or end-users, there have been significant changes over the years in how dev teams build and deliver applications. This shift has been necessitated by the growing need for agility in businesses. Today, enterprises are pushing their teams to deliver new product features, more often, more rapidly, and with minimal interruptions to the end-user experience. Ultimately, this has led to Shorter deployment cycles that translates to: Reduced time-to-market More updates Quicker customer to the production team, leading to faster fixes …

Infosphere Datastage – Standard Practice- Sequence Naming Conventions

Standard practices help you and other understand your work.  This can be very important when working on large teams, working across team boundaries, or when large complex sets of process and objects may be involved.  When you consider the importance of naming convention, when coupled with standard practice, the benefit should be obvious, but often practice doesn’t execute or document their conventions.  So, these standard naming conventions may help when none exist or you need to assemble your own naming conventions. <<SomeIdentifier >> = should be replaced with appropriate information Sequence Object Naming Conventions Entity Convention Master Control Sequence (parent) …

What are the Factor Affecting the Selection of Data Warehouse Naming Convention?

The primary factors affecting the choices in the creation of Data Warehouse (DW) naming convention policy standards are the type of implementation, pattern of the implementation, and any preexisting conventions. Type of implementation The type of implementation will affect your naming convention choices. Basically, this boils down to, are you working with a Commercial-Off-The-Shelf (COTS) data warehouse or doing a custom build? Commercial-Off-The-Shelf (COTS) If it is a Commercial-Off-The-Shelf (COTS) warehouse, which you are modifying and or enhancing, then it is very strongly recommended that you conform to the naming conventions of the COTS product.  However, you may want to …

Data Warehouse – Effective Practices

Effective Practices Effective practices are enablers, which can improve performance, data availability, environment stability, resource consumption, and data accuracy. Use of an Enterprise Scheduler The scheduling service in InfoSphere Information Server (IIS) leverages the operating system (OS) scheduler, the common enterprise scheduler can provide these capabilities beyond those of a common OS scheduler: Centralized control, monitoring, and maintenance of job stream processes Improved insight into and control of cycle processes Improved intervention capabilities, including alerts, job stream suspension, auto-restarts, and upstream/downstream dependency monitoring Reduced time-to-recovery and increased flexibility in recovery options Improved ability to monitor and alert for a mission-critical …

SQL Server JDBC ISJDBC.CONFIG Configuration

This jdbc information is based on Oracle Database 11g Release 2, (11.2.0.4) JDBC for InfoSphere Information Server11.5, and ReedHat Linux 6.  so, here are a few pointers for building an IBM InfoSphere Information Server (IIS) isjdbc.config file. Where to place JAR files For Infosphere Information Server installs, as a standard practice, create a custom jdbc file in the install path.  And install any download Jar file not already installed by other applications in the jdbc folder. Usually, jdbc folder path looks something like this: /opt/IBM/InformationServer/jdbc CLASSPATH  sqljdbc.jar  sqljdbc4.jar  sqljdbc41.jar  sqljdbc42.jar Classpath must have complete path and jar name CLASS_NAMES microsoft.jdbc.sqlserver.SQLServerDriver;com.microsoft.sqlserver.jdbc …
