With the ever-changing economy, the business intelligence landscape is also transforming. According to some predictions, the worldwide spending on IT will continuously increase in 2013 and even at the next few years. The growth drivers may include data visualization, big data, speed, agility, self-service, cloud computing, etc. Therefore, the BI suppliers who have these features will be more competitive compared with their rivals. Business growth turns BI into a daily business processes. Thus demands for new generation BI software are increasing and agility one requirement for those tools. Many BI solution providers carry out technology innovation to meet this demand. Among these providers, Raqsoft, the supplier for statistical computing and analytics software does great job in this aspect. Its main products esProc and esCalc have agile syntax and are very easy to ... (more)

Will Big Data Fall into the Pitfall of Failure?

Recently, I read "Why Big Data Projects Fail" by Stephen Brobst. I can’t agree more with his opinions which exposed the problem I’ve been worried about. In this article, I am going to further discuss this topic to remind the enterprises to beware of falling into such pitfall of failure. t Let’s have a look on a positive example. As a successful enterprise in leveraging big data, how does Google make use of the big data? 1. Collect the row data, capture the contents of each website, e-mail, or Cookie, and extract the key information. 2. Create the complex syndetic index for this inf... (more)

The Truth About Efficient Data Processes in Java Development

In Java development, the typical data computation problems are characterized with: Long computation procedure requiring a great deal of debugging Data may from database, or Excel/Txt Data may from multiple databases, instead of just one. Some computation goals are complex, such as relative position computation, and set-related computation Just suppose a sales department needs to make statistics on the top 3 outstanding salesmen ranking by their monthly sales in every month from Jan to the previous month, based on the order data. Java alone is difficult to handle such computations... (more)

Hadoop + esProc Help You Replace IOE

What is IOE? I=IBM, O=Oracle, and E=EMC. They represent the typical high-end database and data warehouse architecture. The high-end servers include HP, IBM, and Fujitsu, the high-end database software includes Teradata, Oracle, Greenplum; the high-end storages include EMC, Violin, and Fusion-io. In the past, such typical high performance database architecture is the preference of large and middle sized organizations. They can run stably with superior performance, and became popular when the informatization degree was not so high and the enterprise application was simple. With the ... (more)

An Alternative to Stored Procedure in Big Data Computation

As we know, the stored procedure is designed to handle computations involving complex business logics. In the past, the data structure and business logics were so simple that one SQL statement was enough to achieve user's computational goal. With the rapid growing of information industry, users frequently find that they need to achieve the increasingly complex computational goals to out-perform their competitors. To address such computations, SQL alone is far from enough. Database programmers have the additional demands regarding the judge and loop statements, branches at multip... (more)
