In 1978 IBM introduced the System/38 as part of its midrange platform hardware base. One of the many outstanding features of this system was the built-in Relational Database Management System (RDMS) support. The system included a utility for defining databases, screens, and reports. This utility used a form named Data Description Specifications (DDS) to define the database physical (PF) and logical (LF) files (base tables, views, and indexes). In 1988, IBM announced the AS/400. The OS/400 operating system also contained a built-in RDMS, however, IBM offered Structured Query Language (SQL) as an alternative to DDS for creating databases. In addition, SQL Data Manipulation Language (DML) statements were made available as an ad hoc query language tool. These statements could also be embedded and compiled within high level language (HLL) programs. SQL Data Definition Language (DDL) has become the industry standard for defining RDMS databases. Many customers are in the process of modernizing their database definition and the database access. This IBM Redbooks publication will help you understand how to reverse engineer a DDS-created database along, and provides you with tips and techniques for modernizing applications to use SQL as the database access method.

This IBM® Redbooks® publication is focused on melding industry preferred practices with the unique needs of the IBM i community and providing a holistic view of modernization. This book covers key trends for application structure, user interface, data access, and the database. Modernization is a broad term when applied to applications. It is more than a single event. It is a sequence of actions. But even more, it is a process of rethinking how to approach the creation and maintenance of applications. There are tangible deliveries when it comes to modernization, the most notable being a modern user interface (UI), such as a web browser or being able to access applications from a mobile device. The UI, however, is only the beginning. There are many more aspects to modernization. Using modern tools and methodologies can significantly improve productivity and reduce long-term cost while positioning applications for the next decade. It is time to put the past away. Tools and methodologies have undergone significant transformation, improving functionality, usability, and productivity. This is true of the plethora of IBM tools and the wealth of tools available from many Independent Solution Providers (ISVs). This publication is the result of work that was done by IBM, industry experts, and by representatives from many of the ISV Tool Providers. Some of their tools are referenced in the book. In addition to reviewing technologies based on context, there is an explanation of why modernization is important and a description of the business benefits of investing in modernization. This critical information is key for line-of-business executives who want to understand the benefits of a modernization project. This book is appropriate for CIOs, architects, developers, and business leaders. Related information Making the Case for Modernization, IBM Systems Magazine

Data is the currency of the new economy, and organizations are increasingly tasked with finding better ways to protect, recover, access, share, and use data. Traditional storage technologies are being stretched to the breaking point. This challenge is not because of storage hardware performance, but because management tools and techniques have not kept pace with new requirements. Primary data growth rates of 35% to 50% annually only amplify the problem. Organizations of all sizes find themselves needing to modernize their IT processes to enable critical new use cases such as storage self-service, Development and Operations (DevOps), and integration of data centers with the Cloud. They are equally challenged with improving management efficiencies for long established IT processes such as data protection, disaster recovery, reporting, and business analytics. Access to copies of data is the one common feature of all these use cases. However, the slow, manual processes common to IT organizations, including a heavy reliance on labor-intensive scripting and disparate tool sets, are no longer able to deliver the speed and agility required in today's fast-paced world. Copy Data Management (CDM) is an IT modernization technology that focuses on using existing data in a manner that is efficient, automated, scalable, and easy to use, delivering the data access that is urgently needed to meet the new use cases. Catalogic ECX, with IBM® storage, provides in-place copy data management that modernizes IT processes, enables key use cases, and does it all within existing infrastructure. This IBM Redbooks® publication shows how Catalogic Software and IBM have partnered together to create an integrated solution that addresses today's IT environment.

This IBM® Redbooks® publication explains how to configure and manage independent disk pool (IASP) functionality of IBM i 6.1. It is designed to help IBM technical professionals, business partners, and customers understand and implement independent disk pools in the IBM i 6.1. In addition, this publication provides the background information that is necessary to plan, implement, and customize this functionality to your particular environment. It provides guidance on running user applications with either application data or most application objects residing in an independent disk pool. Considering that you can also use independent disk pools in a cluster environment, this publication shows you the basic steps to make your independent disk pool switchable between two Power SystemsTM servers or a single server with multiple LPARs. Independent auxiliary storage pools have many business and technical advantages for Power Systems using IBM i. Not only are independent auxiliary storage pools (IASPs) easy to create and maintain, most applications can use them by simple work management changes. IASPs can provide immediate benefits to your enterprise.

This IBM® Redbooks® publication describes the challenge that most data centers face when updating and modernizing their IT infrastructure. New business demands are driving new applications, joining, and creating in the digital world. A rich, meaningful digital experience is the key to effective engagement in today's integrated digital world. Companies are able to customize digital experiences for their employees with personalized, targeted content for fully connecting with customers, co-workers, and business partners in the most powerful and productive ways. To achieve this, a robust infrastructure is required. Speed of access to data is one of the most important factors. The development of the flash storage devices helped with the insatiable desire for data access speed, but even that is not enough for the most demanding uses. The needs of SAN switches, servers, and software defined infrastructure (SDI) technologies are all requiring more; therefore, the bigger picture needs to be wholly analyzed to build a balanced ecosystem. This publication can help you with planning for growth in your IT infrastructure. This publication explores the concept of modernization and considers important aspects of IT, such as SAN switches, storage systems, and software defined storage.

"Contextual collaboration" is a new term whirling in the industry today. This phenomenal new type of business asset can be realized by two major mechanisms: the components managing mechanism and the services delivery mechanism. The component managing mechanism deals with calendar, workflow, messaging, e-mail, and so on, while the services delivery mechanism deals with receiving and responding to a request. In terms of IBM product offerings, we have Domino for the component managing mechanism and WebSphere for the services delivery mechanism. We need standards to connect the applications from different business entities: your customers, your suppliers, your business partners, and you. These business entities may run their business applications on different platforms, different application languages, different networks, and so on. To connect these un-identical entities together, we need standards. For that, we have Web Service standards such as SOAP, WSDL, XML, and UDDI. This IBM Redbooks publication provides real application scenarios which illustrate how to transform existing Domino applications into either a Web Service provider or a Web Service requester. This is achieved and served through the integration of Domino and WebSphere Application Server.
