Object-oriented (OO) technology is the most important advance in software development in the last thirty years. CTR's 231-page report examines how OO technology's focus on software reuse offers information systems (IS) professionals the potential to develop applications more quickly, with greater reliability and higher quality. The report also evaluates the issues associated with OO performance and the benefits of OO technology.

Has Object-oriented Technology Arrived?

Object-oriented (OO) technology is the most important advance in software development in the last thirty years. As computer languages have evolved from machine to symbolic to high-level procedural languages, the process of application programming has changed more in style than in actual substance. The emergence of OO techniques, however, represents a significant paradigm shift in the approach to building computer applications.

Object technology, once the domain of academics and programming's elite, has entered the mainstream of corporate application development. OO software now pervades every area of the computer industry, governing everything from the way data is stored to how intranet applications are being constructed. OO technology is being considered by the majority of information systems (IS) organizations for mission-critical application development, according to recent research by the Standish Group International Inc.

Organizations considering OO technology implementation are faced with difficult decisions, such as the selection of specific OO tools in the areas of databases, languages, and object request brokers (ORB) which are appropriate to the needs of their application development project.

CTR's new report, Object Technology: The New Approach to Application Development, provides an overall review of OO technology issues and is an invaluable resource for IS managers responsible for evaluating and implementing OO technologies. Various methodologies and key implementation considerations are analyzed, in addition to supporting technologies that enable developers to build OO solutions for the enterprise.

OO Technology Attributes and Benefits Evaluated

The report examines the core components of OO methodology which differ from older application development techniques. The report explains how OO technology's attributes of inheritance, polymorphism, encapsulation, and productivity gains can help an organization attain business goals of cost reduction, better quality products, faster time to market, and closer liaison with customers.

Whatever the theoretical and technological benefits bestowed by objects, there must be a measurable advantage to the enterprise before it will be supported. The report reviews issues such as software reuse and related productivity gains to assess their impact.

OO Database Management Systems

There are an endless array of application types, but almost all deal with data in one form or another. Object Technology: The New Approach to Application Development looks at the myriad of considerations associated with object-oriented database management systems (OODMS), both from a business and technical viewpoint.

Object-oriented Programming Languages and Standards

The chief benefit of object-oriented programming (OOPs) languages is their ability to model extremely complex, real-world entities. Smalltalk and C++ have been the primary vehicles for OO programming. Java is a more recent candidate, although it may be restricted to niche status. Object Technology: The New Approach to Application Development evaluates programming options, including trends in standardization.

The role of standards in object technology is significant. There are pseudo official standards as well as de facto standards that have emerged from the marketplace. The manner in which these competing entities evolve will have a large impact on the technology. The report examines the various choices available.

User Interface Issues Outlined

The modern era in graphical user interfaces (GUIs) began in the mid-1980s with Apple Computer's launch of its Macintosh platform. Microsoft's Windows pursued shortly thereafter and followed, at least conceptually, Apple's lead.

Object Technology: The New Approach to Application Development outlines issues involved with the user interface in an OO environment. The report analyzes GUIs, programming tools, and developing trends in this area.

The report also discusses specific applications in the context of OO application development. The benefits gained by the end-user of an application developed with OO techniques may include: ability to customize functionality, enhanced information sharing across multiple applications, and improved ease-of-use due to objects' modeling of real-world activities.

OO Technology Development, Implementation, and Performance Issues Discussed

Unlike procedural methodology, analysis and design is the most important stage of the OO development process, even more important than the coding itself. Object Technology: The New Approach to Application Development presents the issues and techniques involved with OO analysis and design.

Once an organization has planned, designed, and trained personnel, a system must be implemented. The report reviews general implementation principles, and then examines a client/server (C/S) application based on object technology to offer further insight.

The report also evaluates the issues associated with object-oriented performance, including the most influential design variables. Database factors affecting performance are also discussed.

Right of withdrawal

If you are a consumer you can withdraw from the contract in accordance with the following. Consumer means any natural person who is acting for purposes which are outside his trade, business, craft or profession.

Information regarding the right of withdrawal

Statutory right to withdraw

You have the right to withdraw from this contract within 14 days without giving any reason.

The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.

To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).

We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.

We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.

We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.

You shall send back the goods or hand them over to Revaluation Books, Hounslow, United Kingdom, without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.

Exceptions to the right of withdrawal

The right of withdrawal does not apply to:

The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
