Assume you have a byte-addressable machine that uses 32-bit word (integers are 32-bit) and you are storing the following informa
tion: the string Inventory followed by a value (569)10 followed by another string Price followed by a value (49.75)10. Also, assume that floating point numbers are stored as single-precision IEEE 754 with 127 excess. a) Show (as hex numbers with word boundary) how this is stored on a big-endian machine. b) Show (as hex numbers with word boundary) how this is stored on a little-endian machine.
Option B is the correct answer for the above question.
Explanation:
The data warehouse is a collection of large data or a database that includes historical and operational or current data. This database can be used to make the decisions for the prospects of the organization.
The above question asked about to select the database which can collect the historical and operational data from various source. That type of database is a data warehouse that is described above. Hence option B is correct while the other is not because:-
Option a states about data model which is used to define the database structure.
Option c states about the relational database which is used to collect only current data.
Option d states about the DBMS which is used to manage the relational database.
The process that prepares a data model for implementation as a simple, nonredundant, flexible and adaptable database is known as
C) data analysis.
Explanation:
Data analysis is a process used in critically examining, evaluating data by using logical and statistical techniques.
Data analysis helps in the discovery of important information, data that can be used in the final decision making. the types of data analysis we have are:
