CASE is an acronym for computer Aided Engineering. This involves using software packages to accomplish and automate many of the activities of the information system development including software development or programming. Building Blocks Computer Aided Software Engineering can be a single tool that supports a specific Software Engineering activity to complex environment that encompasses tools, a data of people, hardware, network operating system standards and other components i.e. environment architecture composed of hardware platform and operating system support lays the ground work for CASE. But the CASE environment itself needs other building blocks. A set of portability services provides a bridge between CASE tools and their integration framework and the environment architecture. The integration framework is a collection of specialized programs that enables collection of specialized programs that enables individual’s CASE tools to communicate with one another, to create a project database and to exhibit the same look and Continue reading

The Five Phases of Ethical Hacking
It is debatable, if hacking can be ethical or not, the term “Hacking” over time has been associated with destructive activity. These are some of the terms used in the context of hacking which provides better clarity, Hacker is somebody who enjoys learning hacking for a defensive purpose; an ethical hacker is the security professional who exercises his skills for a defensive purpose. The term Cracker refers to a person who uses his hacking skills for destructive purpose. The ethical question here is in regard to the physical activity of hacking which is sometimes hard to differentiate from cracking. The main difference being, Ethical hacker just identifies vulnerabilities and does not exploit them unlike a cracker. Ethical hacking is the process adopted by ethical hackers to discover the vulnerabilities existing in information systems operating environments. With the growth of internet, computer security has become a major concern for business. Organizations Continue reading
Introduction to Grid Computing
The popularity of the Internet as well as the availability of powerful computers and high-speed network technologies as low-cost commodity components is changing the way we use computers today. These technology opportunities have led to the possibility of using distributed computers as a single, unified computing resource, leading to what is popularly known as Grid computing. Grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common goal. The grid can be thought of as a distributed system with non-interactive workloads that involve a large number of files. What distinguishes grid computing from conventional high performance computing systems such as cluster computing is that grids tend to be more loosely coupled, heterogeneous, and geographically dispersed. Although a grid can be dedicated to a specialized application, it is more common that a single grid will be used for a variety of different Continue reading
What is Enterprise Application Integration (EAI)?
Supply Chain Management (SCM) applications (for managing inventory and shipping), Customer Relationship Management (CRM) applications (for managing current and potential customers), Business Intelligence (BI) applications (for finding patterns from existing data from operations), and other types of applications (for managing data such as human resources data, health care, internal communications, etc) typically cannot communicate with one another in order to share data or business rules throughout a company. Enterprise Application Integration (EAI) is the process of linking such applications within a single organization together in order to simplify and automate business processes to the greatest extent possible, while at the same time avoiding having to make sweeping changes to the existing applications or data structures. Enterprise Application Integration (EAI) is defined as the unrestricted sharing of data and business processes among any connected applications and data source in the enterprise. It is considered as a framework that is formed of Continue reading
Ethical Hacking – Need, Types, Applications and Problems
The word hacking is defined as an illegal use of the other’s computer system or the network resources. Hacker is the term which is formerly meant for the skillful programmer. The word hacker refers to the names of the persons who enjoys the work in learning the details of the computer systems and stretch the capabilities from the system. The system of hacking describes the fast improvement in the new programs that make the codes for the providing a better security to the system with more efficiency. The word cracker also belongs to the same field it make use of the hacking skills for the unlawful purposes like email id, intruding into other’s system. Hacking is of different types such as back door hacking, viruses and worms, Trojan horses, Denial of Services, anarchists, crackers, kiddies and ethical hacking. In the types of hacking system one of the most common hacking Continue reading
Limitations of Enterprise Resource Planning (ERP) Systems
In today’s increasingly competitive world where the world is converging into a single market place, organizations are looking for ways to become globally competitive. Companies must be able to meet customer requirements in the shortest possible time faster than competition and this requires extensive production planning and close coordination between the company and it’s suppliers and customers. MRP (Materials Requirement Planning) was one of the most widely used systems for production planning but it’s main focus was only on managing the production requirements in an organization. MRP systems helped in time phase release of production orders and aggregating planning for material requirements. With time, companies realized that there needed to be an integration of all the functions in an organization and this lead to the development of ERP (Enterprise resource planning) systems. ERP is defined as an Enterprise wide system that facilitates integrated and real-time planning, production and customer response. Continue reading
