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.

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
The Series.divmod() method in the pandas series constructor is used to perform both integer division and modular division operations on series objects with a scalar, or we can apply this divmod() method on two series also.The method performs an element-wise division operation of its two input objects. And it returns a python tuple with two series objects, the first series of the tuple is representing the integer division output, and the second series object of the tuple representing the modulo division output.Example 1import pandas as pd # create pandas Series series = pd.Series([25, 48, 18, 99, 61]) print("Series ...

The divmod() method in the pandas series constructor is used to perform integer division and modulo of two series objects. We can calculate the divmod() of one series with a scalar value. And we can perform element-wise divmod() operation.The method returns a python tuple with two series objects, the first series of the tuple is representing the integer division results, and the second series object of the tuple representing the modulo division results.The method performs an element-wise division operation of two series objects. There is a parameter called fill_value, which is used to fill the specified values in the place ... Read More
The series.dot() method in pandas series is used to perform the dot product operation of two pandas series objects. In mathematics, a dot product of two sequences is given by Sum of multiplication of values at each sequence.The series.dot() takes only one parameter which is another object, it takes a series or an array-like object to perform dot product between elements of each object.Example 1# import pandas packages import pandas as pd # Creating Series objects series1 = pd.Series([1, 0, 5, 2]) print('First series object:', series1) series2 = pd.Series([3, 7, 2, 9]) print('second series object:', series2) ...

SOAP Web ServicesSOAP stands for Simple Object Access Protocol. It is a XML-based protocol for accessing web services. It is produced as an intermediate language so that applications built in multiple programming languages can communicate with each other efficiently. Web services use SOAP for share of XML data among applications.SOAP provides both stateful and stateless operations. Stateful defines that the server keeps the data that it receives from the client across multiple requests. These requests are chained so that the server is aware about the prior requests. Examples are bank transactions, flight bookings, etc. Stateless messaging has adequate information about ... Read More
