You have been accepted as an intern at an IT start-up. In a database design session, you see that phone number, post code and some other attributes have been defined as numeric datatype. Do you think it is the correct decision? If not, suggest the reasons why this is not appropriate.

define the following statistical terms:
1. mean
2. mode
3. median

the following have differing roles within a large IT department in the development of a new computer system. define these roles and responsibilities:
1. project manager
2. technical manager
3. database administrator

Could you expound in database modeling, how subclass and superclass are used? Maybe you can use these terms(cardinality constraint , total participation constraint, weak entity type, partial key, IS-A relationship, specialization and generalization, specific (or local) attribute, specific relationship, aggregation)

1. What does relational closure mean, and what is its significance in application design?
2. What techniques can be used to minimize deadlocks, and how?
3. Compare and contrast performance problems with availability problems.
4. Describe three types of technology that can help alleviate availability issues in a database

Discuss in 500 words or more federated architecture in cloud systems. Remember that this is a cloud class not a database class

Note-Check in chegg writing before you submit it should be 100% unique and don't submit the existing chegg answers,and submit in text format

Draw the corresponding ERD for the following Employee Database:

Employee (emp_id, first_name, middle_name, last_name, date_of_birth)

Dept (Dept_id, Dept_name, Building)

works (emp_id, dept_id, hours)

Emp_phone (emp_id, phone_num)

Note:

Please I need a short answer only on paragraph and simple words.

Sheridan Corporation owns machinery that cost $21,200 when purchased on July 1, 2017. Depreciation has been recorded at a rate of $2,544 per year, resulting in a balance in accumulated depreciation of $8,904 at December 31, 2020. The machinery is sold on September 1, 2021, for $11,130.

Prepare journal entries to (a) update depreciation for 2021 and (b) record the sale.

The inverse demand function for a product by a company that montizes the market is given by v = 200 - 0.03m and supply is given by v = 0.05m

a) Draw and calculate market balance (show price & quantity and a picture)

b)The product damage to society is 70$ per unit. The government uses Pigovjan tax on the production of the company. Update the picture from a) in regards to the Pigovjan tax/1b.

First, create a project that creates an ordered linked list class (use the code provided, make sure to update the insert function so that it maintains an ordered list).

To this class, add a function that prints the list in REVERSE order. Making use of recursion is the easiest and best way to do this, but certainly not the only way.
