Data Profiling with IBM Information Analyzer

by Djoni Darmawikarta | July 2008 | Architecture & Analysis

Data profiling is essentially data mining, but for a different purpose. You mine data to understand, to gain better knowledge about the data. While the more common use of data mining is for gaining the data insights for business purpose (e.g. customer buying characteristics), data profiling is for technical purpose. To be more precise, you do data profiling to gather and analyze the technical metadata characteristics of the data. Information Analyzer, data profiling software from IBM, helps you gain insight into such technical metadata characteristics as, for example, column data type and size (length).

This article is based on a case where a database table grew its size unexpectedly and its initial disk space allocation got strained. Looking at the growth pattern of the table, such as the number of new records (which was not that huge), didn’t give us any clue about the cause of the problem. In this article, Djoni Darmawikarta will step through the Information Analyzer process, run one of its functions called Column Analysis on a simple table (a scaled-down version of the real table), and show how the profiling output help solve the problem.

Data Processing using Derived Column and Aggregate Data Transformations

by Jayaram Krishnaswamy | June 2008 | .NET Microsoft

SQL Server Integration Services, using its designer interface, or BIDS, has made it possible to process data using many of the data flow related items in its Toolbox without writing a line of code. This is a very attractive option for someone who is a beginner with some knowledge of databases, and for end users who may want to look up some detail buried in the data. This tutorial by Dr. Jayaram Krishnaswamy shows how the designed package extracts data from an SQL Server 2005 and processes it using several of its built-in transformations.

Data Modeling Naming Standards with IBM InfoSphere Data Architect

by Djoni Darmawikarta | December 2009 | Architecture & Analysis

 

Many data modelers recognize the advantages of standardizing the names of their modeling objects, particularly when they apply prime-class-modifier words pattern; but, they can’t afford its tedious manual execution.

InfoSphere Data Architect affords functions for building glossary of the standard pattern words that you can then employ while developing and maintaining your data models. This automation encourages the data modeler to apply naming standard to their modeling objects which in turn promotes consistency across their data models.

This article by Djoni Darmawikarta features the naming standard functionality in the glossary model of that IBM software.

Data Modeling and Scalability in Google App

by Amy Unruh | November 2010 | AJAX Java

Google App Engine (GAE) is a platform and SDK for developing and hosting web applications, using Google's servers and infrastructure. Google Web Toolkit (GWT) is a development toolkit for building complex AJAX-based web applications using Java, which is then compiled to optimized JavaScript. Used together, GAE/Java and GWT provide an end-to-end Java solution for AJAX web applications, which can solve many of the problems that arise in developing, maintaining, and scaling web applications.

In this article by Amy Unruh, co-author of the book Google App Engine Java and GWT Application Development, we look at ways to structure and access your data objects to make your application faster and more scalable.

Data Access with ADO.NET Data Services

by Jayaram Krishnaswamy | March 2009 | .NET Microsoft

ADO.NET Data Services leverages the ADO.NET Entity Framework to build data services for relational data sources. These include support for MySQL, DB2, and Oracle in addition to MS SQL Server. It can also be used with non-relational data using an add-on provider model. With ADO.NET Data Services, the developers can build dynamic internet applications (AJAX, Silverlight, etc) that works across intranets as well as the internet. With this in place data access by applications is made possible using URI Syntax and using HTTP verbs operating on the data.

In this article by Dr. Jayaram Krishnaswamy, you will learn how to create a ADO.NET Data Service from scratch. You will also learn how you may access data using the URI constructs. The backend data for this tutorial comes from a copy of Northwind database named TestNorthwind on a named instance of SQL Server 2008. In order to work through this tutorial you should have Visual Studio 2008 SP1 installed. You also need to have .NET Framework 3.5 installed.

Data Access Using Spring Framework: HibernateTemplate

by A P Rajshekhar | October 2009 |

Retrieving data from heterogeneous database servers at Data Access Layer (DAL) has become common while developing enterprise level applications. This, in turn, leads to writing server specific code at DAL level and plugging in a configuration logic that determines which server is to be used at run-time. For an application of medium sized complexity this is well and good. However, as the complexity increases, the server specific code and the configuration logic tend to become part of the infrastructure that runs the application, which in turn adds to the over-all complexity of the application. It is in such scenario that Object Relational Mapping (ORM) frameworks come into picture. These frameworks dynamically generate the required SQL for the targeted database system. Using ORM frameworks the target database system can be changed via configuration file entries. Thus, they take care of configuration logic as well. In this article by A. P. Rajshekhar, we will work with Hibernate, one of the commonly used ORM frameworks.

Dart Server with Dartling and MongoDB

by Dzenan Ridjanovic Ivo Balbaert | January 2014 | Web Development

This article is written by Dzenan Ridjanovic and Ivo Balbaert, the authors of Learning Dart. Dart is a new programming language that may be used both on a client and on a server. On a client, a Dart application may be run in the Dartium virtual machine within the Dart Editor, or as a JavaScript application run in all modern browsers. The application may store its data in local storage. On a server, Dart may use a file system or, through database drivers, both relational and NoSQL databases. A client may communicate with a server with the help of HttpServer and HttpRequest classes. A way to exchange data between a client and a server is by sending and receiving JSON documents.

The todo_mongodb project contains a client subproject called todo_client_idb (idb for IndexedDB, a local storage database), and a server subproject named todo_server_dartling_mongodb (dartling for the domain model framework and MongoDB for NoSQL database with collections of JSON documents). The client is the standard web application called TodoMVC.
