There are issues related with locking including deadlocks which have been discussed later in case of multiprocessors. These things are introducing parallel slowdown and researchers are looking for methods to introduce software level locking approach. Distributed memory has a non-uniform memory access system and for such system to improve parallel computing has to use cache coherence mechanism where cached values are stored and required for smooth program execution.

When two transactions have to be carried in isolation from every where transaction level security is being introduced. It uses either the Secure Socket Layer (SSL) that enables a private channel between clients or servers where data integrity is maintained for messages and authentication for session partners is provided. It uses public and private key encrypting techniques. Another protocol that is being incorporate is the Secure Electronic Transaction (SET) which is an open standard very popular in transactions involving card payments over the internet. This technique also uses encryption and provides the services of authentication, integrity of data and its privacy.

Can users really be co-developers (George)? Web 2.0 proves they can be. With the advent of open-source practices of application development, products are and can be improved on a daily basis. Wikipedia is a perfect example. Users can add and continually update the contents provided by Wikipedia regularly, based on the activities of the users.

The year 2001 served as a turning point for the web with the crash of the dot-com phenomenon. With its crash however, people assumed that it had been overhyped to the extent that such a crash was imminent. However, all technologies are marred by such tremors appearing to be common in most, if not all, technological revolutions. These tremors occur at the time, when new technologies begin to take shape and their new place as the centre of a new phenomenon. This is what separates one technology from the other.

Computer software written for the purpose of managing data bases is being termed as database management system. The activity for which it is being designed includes organization, storage, retrieval and management of data stored in the given database.

A normal pattern that has been observed among hackers is their quest for internal satisfaction and this intrinsic motivation drive them strongly to put their days and nights for the fulfillment of it. They want an inner satisfaction of doing something and staying hidden from the rest of the world.

Another kind of processor level multithreading is the interleaved multithreading where processor switches threads every CPU cycle. The purpose here is to minimize data dependency which means one instruction depends on the preceding instruction, from the execution pipeline, execution pipeline refers to the data processing elements connected in serial fashion having the output of one element being the input of the next which are normally executed in parallel or time-sliced fashion by using buffer storage space. Instruction pipelines in processors allow multiple instructions in the same circuitry to execute in overlapping order. The circuitries is usually divided up into stages, having instruction decoding, arithmetic, and register fetching, where in each stage processes one instruction at the particular time.

Information Systems design and development today involves the use of various different methods and approaches, based on how each fits in the information system development task at hand as well as the operational and the information structure of the organization. Use of these approaches is better than using any approach at all, since it eases the task of an organization to develop a new process (Thompson), gaining acceptance in the organization, modifying it with changing business requirements, and using it to develop applications that fit into the business scenario of the organization using the process.

There are other implications of these philosophies on the overall IS development process, as well. While the engineering philosophy keeps focus on process governing the development / manufacturing of new product, the “human” factor controlling the process is largely ignored. This subsequently reduces the efficiency in developing information systems, as human factors such as the environment, expertise, interaction, team management and others are to be kept in mind for developing any IS development methodology that involves human and social factors as well.

The information loops in VSM are vital to show how functions to be managed in real time. Managers need not to be everywhere at once, only they have to be ensured that the relevant information reaches everybody at the same time and processed by everybody positively. In QP, these loops are responsible for linking five functions together in a precisely defined configuration of interconnection, they are preferred to generate the information related to functioning of operating systems off site and on site locations, coordinating the systems simultaneously, information from the interacting environments to and from the systems, to ensure their coordination, and finally information from the organization as a whole.
