Explain the attributes/quality of good software.

-

 The software product has a number of associated attributes that reflect the quality of that software. These attributes are not directly concerned with what the software does. They reflect its behavior while executing and the structure and organization of the source program and associated documentation.

The essential attributes/quality of good software are discussed below:

a) Maintainability

   The software must evolve to meet changing needs of customers. It is called maintainability. So, Software should be written in such a way that it may evolve to meet the changing needs of customers. This is a critical attribute because software change is an inevitable consequence of a changing business environment.

b) Dependability

       The dependability of software is a property of software that reflects trustworthiness. It is the degree of confidence a user has that the system will operate they expect and the system will not fail in normal use. Software dependability has a range of characteristics, including reliability, security, and safety. Dependable Software should not cause physical or economic damage in the event of system failure.

c) Efficiency

     The software should not make wasteful use of system resources such as memory and processor cycles. Efficiency, therefore, includes- responsiveness, processing time, memory utilization, etc.

d) Usability

       The software must be usable without wasting the effort of the user for whom it is designed. This means that it should have an appropriate user interface and adequate documentation.

What are different steps used in JDBC? Write down a small program showing all steps.

-
 T he fundamental steps involved in the process of connecting to a database and executing a query consist of the following: Import JDBC packages. Load and register the JDBC driver. Open a connection to the database. Create a statement object to perform a query. Execute the statement object and return a query resultset. Process the resultset. Close the resultset and statement objects. Close the connection. These steps are described in detail in the sections that follow. 1. Import JDBC Packages This is for making the JDBC API classes immediately available to the application program. The following import statement should be included in the program irrespective of the JDBC driver being used: import java.sql.*; Additionally, depending on the features being used, Oracle-supplied JDBC packages might need to be imported. For example, the following packages might need to be imported while using the Oracle extensions to JDBC such as using advanced data types such as BLOB, and so on. import o...

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

a) A Snowflake Shema is shown in figure below: b) The specific OLAP operations to be performed: 1. Roll-up on course from course_id to department. 2. Roll-up on a student from student_id to university. 3. Dice on course, student with department ="CS" and university = "biguniversity" 4. Drill-down on a student from the university to student_name. c) N = 4 dimensions The cube will contain 54 = 625 cuboids.

Discuss classification or taxonomy of virtualization at different levels.

-

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...
