The reliance on _____ as the design methodology for relational databases is seen as a stumbling block to its use in OLAP systems

hammer [34]

Answer:

The reliance on ______ as the design methodology for relational databases is seen as a stumbling block to its use in OLAP systems:

c. normalization

Explanation:

The OLAP systems are those type of software that are used to analyse the data stored in a database. OLAP stands for online analytical processing. This software allows the user to analyse different data like demographic data etc.
The reliance on normalization as the design methodology for relational databases is seen as stumbling block to its use in OLAP systems because in operations like creating, retrieving, updating or deleting of data, the de-normalization structure is preferred instead of normalization as we can avoid the data duplication as well as to increase the speed of processing.

maksim [4K]

Answer:

B. GRID COMPUTING , ON - DEMAND COMPUTING AND REAL TIME COMPUTING

Explanation:

Grid computing, on-demand computing and real time computing are currently the most impactful information technology processes. The Grid computing from example entails distributed computing whereby computing resources are distributed across different systems for a computing task. This is seen in server systems where a super virtual computer composed of a network of computers are connected to share resources and perform large tasks. This form of computing has majorly affected and improved complex computing tasks today.

On demand and real time computing are also other notable trends in IT with real time computing bringing the power of live and direct coverage of information to our screens and on demand making it possible for the average user to access computing resources as needed such as in the services of cloud computing providers

What type of printer heats toner to adhere it to the paper? inkjet . impact. 3D. laser.

Luden [163]

Answer:

laser

Explanation:

These are well known printer types now. Let's review how they work to determine in which does heat plays a role.

inkjet: inkjet printers are printer throwing ink at the paper in the form of little drops. No heat involved here.

impact: That's the oldest technology, where a printing head is moving left and right to punch a printing ribbon and transfer ink onto the paper. No heat involved.

3D: 3D printers don't usually use paper... as they use other materials to create a 3D representation of a model. Heat is involved in the melting of the material before it's placed on the building model. But no paper involved here.

laser: laser printers are working very much like a photocopier machine... memorizing the pattern to be printed, then transferring it onto paper... using heat.

BITS wants to store information about the supervisors, including their supervisor number and the relationship to consultants. Su

Olin [163]

Answer:

Convert the table into normalize form

Explanation:

Un normalized relation of the given schedule is as

Consultant ( ConsultNum, Last Name, First Name, Street, City, ZipCode

HoursRate (SupervisorNum, Supervisor Num)

(Tasks, Description, Catagory, Price, SupervisorNum))

According to these functional dependencies :

SupervisorNum is dependencies of the SupervisiorNum

ConsltNum is dependencies of the Last Name, First Name, Street, City, ZipCode, Hours, Rate

Tasks are dependencies of Description, Category, Price

The consultant table is not in a normalized form as it contains repeating groups. Make composite keys such as Supervisor Num, Tasks and ConsltNum and convert the table in NF by removing repeating groups

Such as table in NF

Consultant

(Consult Num, Last Name, First Name, Street, City, Zip Code, Hours, Rate

Supervisor Num, Supervisor Name, Tasks, Description, Category, Price)
