TestNG supports multiple ways to skip or ignore a @Test execution. Based on requirement, a user can skip a complete test without executing it at all or skip a test based on a specific condition. If the condition meets at the time of execution, it skips the remaining code in the test.Following are the ways to skip a @Test execution −Use the parameter enabled=false at @Test. By default, this parameter is set to True.Use throw new SkipException(String message) to skip a test.Conditional Skip – The user can have a conditional check. If the condition is met, it will throw SkipException ... Read More
Data SecurityData security define the collective measures used to protect and secure a database or database management software from improper use and malicious cyber threats and attacks. Database security is a layer of information security. It is basically concerned with physical protection of information, encryption of information in storage and data remanence issues.Data security is generally defined as the confidentiality, availability and integrity of data. In another terms, it is all of the practices and processes that are in place to provide data isn't being used or accessed by unauthorized individuals or parties. Data security provides that the data is ... Read More
Confidentiality defines that sensitive information should be prohibited from being disclosed to illegal parties. There are generally two methods, or an amalgamation of these, in the course of which confidentiality can be supported. One method is to limit access to the information that should be maintain undisclosed. The other method is to encrypt the secret information. Confidentiality is at times also referred to as secrecy.The goals of security are confidentiality. It can strengthen internal control and restrict unauthorized access from both internal and external factors, thereby securing the confidentiality and integrity of resources and assets.Role-based security methods can be employed ...

Physical SecurityPhysical security is represented as the security of personnel, hardware, programs, networks, and data from physical situations and events that can support severe losses or harm to an enterprise, departments, or organization. This contains security from fire, natural disasters, robbery, theft, elimination, and terrorism.Physical security is an essential part of a security plan. It forms the basis for some security efforts, such as data security. Physical security defines the protection of building sites and equipment (some data and software contained therein) from theft, vandalism, natural disaster, man-made catastrophes, and accidental damage (e.g., from electrical surges, extreme temperatures, and spilled ...

A Global information system is a system that generates, manages, analyzes, and maps all types of data. GIS connects data to a map, integrating location information with all types of descriptive data. This supports a foundation for mapping and analysis that is used in science and almost each industry.GIS provides users understand patterns, associationship, and geographic context. The benefits involve improved communication and efficiency and better management and decision making.The information system of an organization can be defined as a system that serves to provide information within the organization when and where it is required at some managerial level. An ... Read More
Service-oriented Architecture (SOA) is an approach of designing software to provide services to applications, or to other services, through published and discoverable interfaces. Each service provide a discrete chunk of business functionality by a loosely coupled (usually asynchronous), message-dependent communication model.The design of a high-quality software solution, including some other complex structure, needs early architectural decisions assisted by well-understood design methods, structural designs, and styles. These patterns address general service concerns such as scalability, reliability, and security.There are some aspects of Service-oriented architecture which are as follows −Architectural versus Implementation Models − As IT professionals goes to deliver applications using ...

SOA stands for Service Oriented Architecture. It is a type of software design that creates software element reusable using service interfaces that use a common communication language over a network.A service is a self-included unit of software functionality, or set of functionalities, designed to complete a specific task including retrieving specified data or executing an operation. It includes the code and data integrations necessary to carry out a complete, discrete business function and can be accessed remotely and communicated with or updated separately.In another terms, SOA integrates software elements that have been independently deployed and maintained and enable them to ...

In the pandas series constructor, the method called dropna() is used to remove missing values from a series object. And it does not update the original series object with removed NaN values instead of updating the original series object, it will return another series object with updated values.The parameters of the dropna() method are axis, inplace, and how.Example 1# importing packages import pandas as pd import numpy as np # Creating Series objects sr = pd.Series([42, np.nan, 55, 42, np.nan, 73, np.nan, 55, 76, 87], index=list("ABCDEFGHIJ")) print('Series object:', sr) # Remove missing elements result = sr.dropna() ...

In the pandas series constructor, there is a method called drop() which is used to remove specified rows from the pandas series object. It won’t update the original series object with deleted rows instead of updating the original series object, it will return another series object with the removed rows.We can use this drop() method on both labeled-based and positional-indexed series objects.It will raise a Key error if the specified row labels are not found in the index of the series object. We can suppress the errors by setting the errors parameter from raise to ignore. And we have some ... Read More
The pandas series.drop() method is used to remove a specific row from the pandas series object. And It will return a series object with the removed row.The drop() method can be applied to both labeled-based and position index abased series objects. The parameters of this drop() method are labels, axis, level, inplace, and raise.It will raise a Key error if the specified row label is not found in the index of the series object. We can suppress the errors by setting the errors parameter from raise to ignore.Example 1# import pandas package import pandas as pd # Creating Series ... Read More
