<span>If a user name can have seven letters (with no distinction between upper and lower case), and if a letter can be repeated, then the maximum number of names is 26x26x26x26x26x26x26, or 8,031,810,176. That is, slightly more than eight billion names are possible.</span>

Identify and describe the kind of trouble ticket system you would recommend in the following scenario hey small marketing firm d
yarga [219]

Answer:

There is no hesitation at all that the company is going through recession, and will for next 10 years. Hence, we need to be crystal clear with our budget for this company, and provide low cost solutions. The company requires trouble ticket system. The simplest can be a back-end service to store trouble ticket details, and with API like ticket check, cancellation on fraud and many such. However, the company can select the most important from this list as well, and leave the remaining, as software company is going to charge for this.  Also. we can build a simple app for the company with APIs that we developed with good design, and we can make use of web socket programming to ensure client server communication, and data transfer. We can make use of the chatbots as well, and that is the cheapest definitely currently.

Explanation:

The answer is self explanatory.
