What are the factors affecting the purchasing decision for dbms software?

Usability

Consider how user-friendly the system will be for all those members of staff required to use it. In some organisations those may include Marketing professionals, the IT department, Database Developers and others. Look at the suitability from everyone’s perspective, and consider if you can set different levels of permission for different teams or personnel.

Visualisation & Reporting

Review the ease of visually analysing and displaying results for any queries you run on your data, while making selections and deciding segments. Also, check how the software displays campaign results if you feed this information back into the database.

You should look for visual displays that will help you show selections and results to colleagues (likely other teams or managers/directors) in a way that they will be able to understand quickly and easily.

Security

Security of your data is an essential aspect of any database implementation. Business-sensitive data and any personal information you hold must be stored securely to adhere to regulations and to protect it from loss or theft.

It is important to consider both the physical risk to data (e.g. the risk from fire, theft, etc.) and the risks from hacking, or from unintentional corruption of data through human error. Any system you implement must address the issue of keeping your data secure.

Functionality

Confirm that the modules available in the data analysis software meet your business requirements. The functionality or modules you should be looking for include:

Extract and filter data

Insight and analysis

Segmentation and modelling

Automation

Forecasting strategy

Results visualisation

Campaign planning and ROI management.

Support & Development

Think about the support service the software company offers for its solution. Is this available during the hours you are likely to need support? Is the support offered by email, phone, other?

Ensure there is a development plan for the selected software so that you can be confident it will grow with emerging technologies. Make sure you will receive upgrades to the most recent version and that you will be supported for as long as you use that software.

Integration

Does the system you are considering integrate with your other software systems such as your Email Marketing platform and CRM system? This may be a direct integration to the specific software of there may be an open source code available for integrations.

Scalability

Ensure that the system has the capacity to grow with your data and your business. Remember you are likely to be adding to the data all the time, so even though your requirement may not be huge right now, this can grow very quickly if you are gathering and updating your data regularly as planned. Essentially…can it easily manage millions of rows of data?

Cost and Suitability

Whilst cost is obviously a factor in any business expenditure, it is wise to ensure that – as far as possible – your decision is based on the software being fit for purpose.

It could be a costly mistake to take on a system that you then invest time in building, only to find – too late – that it is not advanced enough for your needs. Equally there is no need to opt for the most expensive software available, if you are unlikely to need much of the functionality it offers.

Hosting

Where is your system going to be located (physically)? Will you take the system in-house or engage the services of a company to host the data and the software system for you. This could have implications for support, cost (including any additional hardware you would require), security, and possibly speed.

Updates

The two most important factors regarding updates to the database are frequency and automation.

Do you need data to be live and constantly in sync with your other systems, or would daily or even weekly updates to the database be sufficient? Consider that in order to automate the update process, you will typically need a consistent data source, i.e. the field types, and the files supplied each time must be the same. You should consider how often source data is likely to change, if you are ever going to import additional data and if so how your chosen software will deal with this.

Write a program that calculates the future value of an investment at a given interest rate for a specified number of years. The
baherus [9]
<h2>Question:</h2>

Write a program that calculates the future value of an investment at a given interest rate for a specified number of years. The formula for the calculation is as follows:

futureValue = investmentAmount * (1 + monthlyInterestRate) ^ years * 12

Note: Allow users to enter the values of the investmentAmount, monthlyInterestRate and years from standard input.

Assume the number of years is always a whole number.

<h2>Answer:</h2>

===================================================

//import the Scanner class

import java.util.Scanner;

//Class header definition

public class FutureValue{

   

    //Main method definition

    public static void main(String []args){

       

       //Create an object of the Scanner class

       Scanner input = new Scanner(System.in);

       

       //Prompt the user to enter the investment amount

       System.out.println("Enter the investment amount");

       

       //Store the input in a double variable called investmentAmount

       double investmentAmount = input.nextDouble();

       

       //Next, prompt the user to enter the interest rate

       System.out.println("Enter the interest rate in percentage");

       

       //Store the input in a double variable called interestRate

       double interestRate = input.nextDouble();

       

       //Convert the interest rate to decimal by multiplying by 0.01

       interestRate *= 0.01;

       

       //Convert the interest rate to monthly interest rate by dividing the

       //result above by 12

       double monthlyInterestRate = interestRate / 12;

       

       //Prompt the user to enter the number of years

       System.out.println("Enter the number of years");

       

       //Store the input in an integer variable called years

       int years = input.nextInt();

       

       //Using the given formula, find the future value

      double futureValue =  investmentAmount * Math.pow(1 + monthlyInterestRate, years * 12);

       

       //Print out the future value

      System.out.println("Future value : " + futureValue);

       

    } //End of main method

     

}  // End of class definition

===================================================

<h2>Sample Output</h2>

===================================================

<em>>> Enter the investment amount </em>

1000

>> <em>Enter the interest rate in percentage </em>

10

>> <em>Enter the number of years </em>

5

Future value : 1645.3089347785854

===================================================

<h2>Explanation:</h2>

The code above has been written using Java. The code contains comments explaining every line of the code. Please go through the comments. The actual lines of code have been written in bold-face to distinguish them from comments. A sample output has also been provided as a result of a run of the code.
