U2 PDO Driver, Part 1: Write a PHP Data Objects driver for U2
PHP Data Objects (PDO) extension provides a lightweight, convenient means for accessing databases in PHP. However, you must use a database-specific PDO driver to access a database server. Currently there is no PDO driver for U2 data servers. In this article, you'll learn how to write a PDO driver for U2 using U2 native interface InterCall. With this PDO driver, U2 users can develop PHP applications that access U2 data quickly and easily.

U2 SELECT verb list extension
This article provides a general solution to the problem of record selection based on a large
list of non-primary-key values. It is a step-by-step guide to building a new verb which selects records based on a
match between dictionary values and standard UniData SAVE.LIST and SELECT buffer lists.
For those who like to build their own tools, it offers an interesting project. For those who prefer to use tools
others have built, the completed verb source code is available as a download.

U2 Compact Framework
Rapidly evolving client needs are driving advances in information technology that are
making the world seem smaller and flatter.
One of the basic underlying requirements of these needs is
access to information anywhere, on any device, at any time.
The U2 UniObjects for .NET Compact Framework (UO.NETCF) library makes this
kind of access possible.
This article provides an example of how to take an existing PC-based application
that communicates with a U2 database, and use it as the
basis for developing a new mobile application using UO.NETCF.

U2 encryption in an open technology world
If you have valuable, sensitive, or confidential data, and the data can be accessed or seen by unauthorized people, then data encryption is a must. The extended BASIC APIs of IBM UniData and UniVerse (U2) perform symmetric encryption operations on data using various available ciphers. The heart of the U2 encryption function is the OpenSSL library. Walk through the four worlds of encryption covering C#, Java, U2 BASIC, and OpenSSL shell scripting and see that encryption of data produced is interchangeable amongst them.

Validate data types in U2 using XML schema
IBM U2 (IBM UniData and IBM UniVerse) stores all of
its data without any type validation. Thus the same field can contain an integer, a
string, or even an internal date structure. While this may be useful to the
application developer, it can cause problems when integrating the data from your U2
environment to an external environment. In this article, validate the data against a schema and prevent invalid data with update triggers.

IBM U2 and Service Oriented Architecture (SOA)
Service oriented architecture is an application framework that takes everyday
business applications and breaks them down into individual business functions and processes, called services. SOA lets you build, deploy, and integrate these services independent of applications and the computing platforms on which they run, making business processes more flexible. In this article, learn how IBM UniData and UniVerse (U2) technology relates to SOA.
