Levels of transformation It refers to various steps for converting data from one format or structure to another format. It is a fundamental feature of most data integration and data management tasks such as data integration, data warehousing and application integration. It can be simple or complex based on the required changes to the data between the source and target data. There are seven main levels of transformation which are problems, algorithms, language, machine architecture, microarchitecture, circuits and devices. Abstraction Abstraction is the process by which lower level details are hidden and information that is required only for understanding a particular level is displayed. It is the process of taking away or removing characteristics from something for reducing a set of essential characteristics. It is related to both encapsulation and data hiding.

Security in general means the protection of an asset. In the context of computer and network security, explore and explain what assets must be protected within an online university. What the threats are to the security of these assets, and what countermeasures are available to mitigate and protect the organization from such threats. For each of the assets you identify, assign an impact level (low, moderate, or high) for the loss of confidentiality, availability, and integrity. Justify your answers.

Object-Oriented Programming In this separate files. ent, you'll need to build and run a small Zoo in Lennoxville. All classes must be created in Animal (5) First, start by building a class that describes an Animal at a Zoo. It should have one private instance variable for the name of the animal, and one for its hunger status (fed or hungry). Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider how these should be named for code clarity. For instance, using a method called hungry () to make the animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's being fed: public void feed () { this.fed = true; Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it answers when compared to get Fed. Keep this technique in mind for future class designs. Zoo (10) Now we have the animals designed and ready for building a little Zoo! Build a class…
