Invest More beyond Tools to Improve Reporting Performance

As a type of front-end data service intended for end-users, reports in applications have received a lot of concerns about their performances.  It’s all users’ wish that parameters in and query and aggregate results out in no time. Though less than twenty seconds’ waiting time is within a tolerant range, three to five minutes will threaten to extend beyond a user’s patience with the worst product experience.But why is a report so slow? And how shall we optimize its performance? Data…See More

Don’t Allow Yourself to Be Hoodwinked by Unstructured Data Analytics Technology

By JIANG Buxing, Data Scientist As big data concept gains momentum, unstructured data analytics technology is becoming hot.  It is said that 80% of all data in an enterprise is unstructured, which is roughly true when it is measured by the space, considering the large size of the audio and video data. With huge amounts of data at hand, some technique is required to analyze them.But make sure you are not misled by the universal unstructured data analytics technology? There is no universal…See More

Four Ways to Improve Back-end Performance for Multidimensional Analysis

 By JIANG Buxing, Data Scientist Multidimensional analysis, commonly called OLAP, is an interactively data analysis process that performs operations, including rotation, slice and dice, drilldown etc., on a data cube. The structure of its back-end computation is simple, as shown by the following SQL:SELECT D,..., SUM(M), ... FROM C WHERE D'=d' AND ... GROUP BY D,...The statement aggregates some measures by some dimensions. C is a data cube, D,… represents dimensions to be selected, and M,……See More
