John Valance presented at NHMUG on Thursday March 22, 2018
John presented the following sessions:
Connecting the Dots (intro to web development with PHP)
This presentation is for beginner to novice web programmers, or those who would like to understand the technologies and languages involved in a typical web application.
SQL Stored Procedures and Application Modernization
Among the many modernization technologies available on IBM i, SQL is perhaps the one best known by RPG developers. This session won't focus on how to write SQL statements, but rather how to write scripts that combine SQL statements together into procedures that encapsulate database access and core business logic for use in a myriad of modern applications. We'll discuss how stored procedures fit into a modernization strategy, and why they are such a good fit for RPG programmers who want to participate in modernization projects. They're also a great fit for anyone new to IBM I who needs access to its database for applications in PHP, Java, Crystal Reports, IBM Web Query, Excel, Web Services, conversion projects, etc.
SQL is often embedded in other languages, such as RPG, PHP, Java, etc. But IBM provides the SQL Procedure Language (SQL/PL), which can be used to code complex or multiple SQL statements into procedures that can form the backbone of a service oriented architecture. These procedures can be called from any programming language. This can simplify the database access code in PHP, Java, and other host languages, while taking full advantage of DB2-specific SQL features.
Come and learn about the many features and benefits of SQL stored procedures, how to code them, and how to use them in your modernization strategy.
Case Study: B2B e-Commerce With PHP on IBMi
This session will describe a recently completed project to create an online wholesale ordering system for a beverage manufacturing and distribution company with a BPCS/LX backend. The requirement was to create a browser-based order entry system for wholesale customers that do not have EDI capability. The system needed to have a simple, modern, intuitive interface, usable on desktop and tablet browsers. The order submission procees needed to feed into a BPCS/LX backend. The server language of choice was PHP, using Zend Framework 2.
This will be a high-level, project management focused presentation, highlighting the technologies and methodologies employed, and challenges faced and how they were resolved. Some of the topics to be covered include: requirements gathering, wireframing, HTML design, use of offshore resources, controlling database access with stored procedures, integration with ERP system, PDF form generation, e-mail acknowledgements, SSL setup, and security.
If you are considering creation of an e-commerce system, please come with your questions and learn how we got this system off the ground.
