Data reduction is a process that reduced the volume of original data and represents it in a much smaller volume. Data reduction techniques ensure the integrity of data while reducing the data. The time required for data reduction should not overshadow the time saved by the data mining on the reduced data set. In this section, we will discuss data reduction in brief and we … [Read more...] about Data Reduction
Data Integration
Data integration means merging data from several heterogeneous sources. While performing the data integration you have to deal with several issues such as data redundancy, inconsistency, duplicity and many more. In this section, we are going to discuss data integration at a stretch and along with that, we will also discuss the issues or challenges faced during data … [Read more...] about Data Integration
Data Cleaning
Data cleaning is the technique used to eliminate the inconsistencies and irregularities in the data. Redundant or irrelevant data only increase the amount of storage. So, it is very important to clean the data as the inaccurate data not only confuses the data mining programs but also degrades the quality of data. In this section, we will discuss data mining in brief along … [Read more...] about Data Cleaning
Data Warehouse Architecture
Data warehouse architecture is about organizing the building blocks or the components in such a way that they extract more benefit for an enterprise. It’s all up to the requirement of the enterprise whether it wants to stress on a specific component or boost any other component with tools and services. In this context, we are going to discuss the architecture of the data … [Read more...] about Data Warehouse Architecture
Data Warehouse and its Features
A data warehouse can be defined as an informational environment that assists in extracting strategic information that is useful in making the strategic decision for the betterment of the enterprise. In this context, we will define the data warehouse in brief along with the features that explain how data warehouse provides an integrated view of an entire enterprise. We will … [Read more...] about Data Warehouse and its Features
Need of Data Warehouse
A company experiences the need of data warehouse when the executives and managers of the organization require the strategic information for taking decisions that keeps the company competitive in the market and ensures the company's survival. In the early 1960s, the computer system emerges as an essential requirement as they would perform order processing, payment billing, … [Read more...] about Need of Data Warehouse
System Design
System design is all about planning the systems architecture where the developers have to take some high-level decisions. The developers organize the whole system into subsystems further allocate these subsystems to hardware and software. During the development of software, the system design stage occurs after the analysis stage. The analysis stage concentrates on what … [Read more...] about System Design
Domain State Model
Domain state model describes the behavior of the classes that express several distinct states. The domain state model also describes the constraints on the object when it in a certain state, its properties, and also the events that trigger an object to transit from one state to another state. Not all the classes require a state diagram to express their behavior as they can … [Read more...] about Domain State Model
Domain Class Model
Domain class model defines the real-world classes and the relationship between them. In our previous content, we have studied that during the software development process the domain modelling occurs at the analysis phase. Domain analysis figures out real-world objects from the problem statement that are important from the application point of view by creating the domain … [Read more...] about Domain Class Model
Software Development Process
Software Development Process presents an organized way to develop software from an idea to a deliverable product. This process includes well-defined techniques which are followed in a particular order to obtain a product of high quality, lowest cost and in minimum time duration. The order of these techniques may vary depending upon the requirement of the software. Each … [Read more...] about Software Development Process
