Answer:
The challenge of cost control
The challenge of competence
The challenge of reduced system delivery times.
Explanation:The Challenge of Cost control is a major challenge affecting the software engineering in the 21st century,the cost of Microchips and other hardware are constantly rising.
The challenge of competence is another major challenge affecting software engineering in the 21st century,as most software engineers lack the required competence to handle some of the issues facing softwares.
The challenge of reduced system delivery times is a major challenge likely to affect software engineering in the 21st century,as people required the software to be available in the shortest possible time.
Answer:
The answer to this question can be described as follows:
Explanation:
Given data:
Performance of the CPU:
The Fastest Factor Fraction of Work:
Current Feature Speedup:
1.5
CPU upgrade=6000
Disk activity:
The quickest part is the proportion of the work performed:
Current Feature Speedup:
Disk upgrade=8000
System speedup formula:
Finding the CPU activity and disk activity by above formula:
CPU activity:
Disk activity:
CPU:
Formula for CPU upgrade:
DISK:
Formula for DISK upgrade:
equation (3) and (4),
Thus, for the least money the CPU alternative is the best performance upgrade.
b)
From (3) and (4) result,
The disc choice is therefore the best choice for a quicker system if you ever don't care about the cost.
c)
The break-event point for the upgrades:
=4702.19 x-0.5
= -2351.095
From (2) and (3))
Therefore, when you pay the sum for disc upgrades, all is equal $ -2351.095
Answer:
The database models depend very much on what will be the use in the business logic of the company will have directly with the database, primarily implying whether or not to use a relational or non-relational database.
Explanation:
In relational databases there is something called normalization, which after the construction of a data model allows me to optimize in a greater way the way in which I will make the queries within this database, that is a fundamental aspect, since one of the fundamental aspects today about the business logic of companies with databases is the capacity to respond when waiting for a query and if it is delayed a lot there will be inconvenience with the expected result.
Currently there are different examples of in which scenario what kind of database is better, distributed, centralized databases, clusters is.. And it is where you need to be very clear about what is my business and what type of database is adapted more to be.
I hope I could help you.
