2. Data Integration
3. Data Selection
4. Data transformation
5. Data Mining
6. Pattern Evaluation
7. Knowledge presentation
Explanation:
The steps involved in data mining or data analytics when viewed as a process of knowledge discovery includes the following:
Step 1. Data cleaning: this involves the elimination of inconsistent data.
Step 2. Data integration: this involves the combination of data from multiple sources.
Step 3. Data selection: this is the step where significant data for task examination are gathered from the database.
Step 4. Data transformation: this the step in which the data are modified for mining by conducting the aggregate operation.
Step 5. Data mining: this step involves the extraction of data patterns through specific techniques.
Step 6. Pattern evaluation: this step involves the identification of patterns that depict knowledge based on measures.
Step 7. Knowledge presentation: this is the step in which visualization and knowledge representation methods are utilized to illustrate mined knowledge to users.
Answer:
NULL is the correct answer of this question.
Explanation:
The insert statement is used for inserting a column list into the database this statement is an under Data Manipulation language.When we insert any column into the database there is always a null value stored.
- Insert statement is used to insert the data into the database .
- To insert data following syntax is used:-
insert into tablename (column data type).
- When we insert any data into the database the default value is stored is bull.
Answer:
The rising power of computers and advances in Artificial Intelligence has reenergized the debate of intelligence of computers relative to humans. Human brain has about 100 billion neurons which are often compared to gates in computers.
Explanation:
Answer: an Arithmetic Logic Unit (ALU) that knows how to add numbers
Explanation:
The CPU can process those instructions easily, thanks to a control unit that knows how to interpret program instructions and an Arithmetic Logic Unit (ALU) that knows how to add numbers. With the control unit and ALU combined, the CPU can process much more complex programs than a simple calculator.
