Input controls are used to ensure that the data entered into a system is correctly, completely, and is secure. The input controls can help the flow of data in a database to be the same format and easy to understand. There are many times of input controls, however the paper goes into detail about four types of input control which are: input mask, validation rules, source documents, and batch input. Without input controls there can be data integrity errors that could occur and cause information to be incorrect in the database. There are advantages and disadvantages to restricting user interfaces to limit a person ability of typing in too much information or maybe not enough information.
When building a database to house large amounts of data and if many people have access to the database, people may type in information differently than another person. Some people my write the date as 2-09-12 while another may write it as 9 Feb 12. Input controls are used to make sure that people use the same format for all data entered in the database or convert all the dates to the same format such as February 12, 2012. Input controls can also be a preset of information to be entered into a form by a drop-down list or list box. For an example a drop-down list may have a state broken up into 5 regions, north, south, east, west, and central. When data is entered in, the person has to pick the region the information needs to be under to be able to organize the data and complete the input form. “Data can be entered into a computer application from either manual online input or by scheduled automated processing. The input control reviewer should determine the adequacy of both manual and automated controls over data input to ensure that data is input ...

...data. Limiting form formats is also an advantage because the format of the data entry will be the same. The disadvantage would be if a person is used to using a different format, the system would not accept their format and the user would have to re-input that information causing some delay to process the record until the user gets used to the company format.

In the essay “Population, Delusion and Reality,” Amartya Sen discusses two opposing approaches to population control. These two approaches are “collaboration” and “override” The collaboration approach calls for a voluntary choice as well as a collaborative solution to controlling the population growth. The collaborative approach relies on more choices for men and women, a more educated and rational decision on the part of both men and women, and an open arena for a more extensive discussion on such subjects. These men and women are able to make such rational decisions based on the opportunity to be more educated and with a sense of self-confidence when presented with the ability to do so by having public policies such as family planning, health care, bigger and better education facilities and a sense of economic well being. Our ability to solve problems by making rational and educated decisions seems like a better alternative than to forcing a resolution. The “override” approach works by means of legal or economic coercion, such as the means that China forces with their “one child policy.” With this approach, the government may deny individuals of job opportunities or deny housing. These people are left with no other choice but to follow along with what the government would want them to do.

Internal controls are increasingly a crucial part of any business large or small. Controls serve two purposes according to financial accounting chapter eight; they safeguard assets and enhance the accuracy and reliability of accounting records. Expanding on that concept internal controls are put in place as a result of activities that have occurred in the past and are an effort to protect internal and external users. Internal controls safeguard company assets by outlining fair and efficient regulations in an effort to prevent theft. Regulations designed to establish responsibility, segregation of duties, and accountability protect investors, management, and the public. The result of a financial outrage and catastrophes of WorldCom, Enron, Tyco, Hollinger, and Tyco necessitated the need for better regulation and control leading to the creation of the Sarbanes Oxley Act (SOX).
530). The risks assessment suggests to identify and manage critical documents and store them on a centralized application and file servers. Moreover, it proposes to use applicable controls. To further explain the applicable controls, role based control (RBAC) should be enabled to regulate access to the files resources based on the roles of individual users within the company. In this structure, access is the ability of an individual user to perform a specific task, such as view, create, or modify a file. Roles are defined according to job proficiency, authority, and responsibility within the business. In fact, role describes the level of access that users have for their account. For example, by assigning roles to users, administrators can allow multiple users to complete tasks securely. Also, RBAC limits risk by ensuring that users do not have access beyond their training or level of control. Thus, an employee 's role determines the level of permissions granted and ensures that junior level employees are not able to access sensitive information or perform high level tasks. Additionally, an employee education and security awareness program should be implemented to improve employee behavior, hold employees accountable for their actions, complying with rules, and improve employee knowledge base on
It would help in tracking payment receivables, account payables, and ensure that the amount due for and by the Company are completed in time. Likewise, the payroll system allows the follow up, which would ensure that the money owed to the Company is paid within the time set. · Effective internal control system to safeguard the Company
The database application design can be improved in a number of ways as described below:

In the Orlando office we have three main databases. We have a Microsoft Access Database, a Visual Source Safe database, and a Microsoft SQL server database with a custom web client front end. The Microsoft Access database is fairly simple. We use this data base to keep track of the computer hardware and software configurations that are used when doing quality assurance testing and problem replication and troubleshooting of the software product. For any one product we can have up to twenty or thirty different configurations. Initially keeping track of the configurations along with the machine name and IP address was done on paper with a grid like matrix. After a short period of time, this became extremely time consuming and impractical. A simple database was set up in Access and then the database was shared to allow each user to be able to find out what configuration each computer was in for that day or that week so that the proper tests and or bug reporting could be conducted. The database allows the users to search by software version, platform type, operating system, machine name, IP address, memory size, and several other items that are not as significant. Before the database was created the engineer would have to leave their desk find the chart and to a cross reference using the matrix that was drawn up, and hopefully that matrix was kept up to date. Now as the technicians update or change the machine configurations they can enter that information immediately into the database and it will automatically provide a matrix view or a tabular view for any engineer who needs it.
Inconsistently storing organization data creates a lot of issues, a poor database design can cause security, integrity and normalization related issues. Majority of these issues are due to redundancy and weak data integrity and irregular storage, it is an ongoing challenge for every organization and it is important for organization and DBA to build logical, conceptual and efficient design for database. In today’s complex database systems Normalization, Data Integrity and security plays a key role. Normalization as design approach helps to minimize data redundancy and optimizes data structure by systematically and properly placing data in to appropriate groupings, a successful normalize designed follows “First Normalization Flow”, “Second Normalization Flow” and “Third Normalization flow”. Data integrity helps to increase accuracy and consistency of data over its entire life cycle, it also help keep track of database objects and ensure that each object is created, formatted and maintained properly. It is critical aspect of database design which involves “Database Structure Integrity” and “Semantic data Integrity”. Database Security is another high priority and critical issue for every organization, data breaches continue to dominate business and IT, building a secure system is as much important like Normalization and Data Integrity. Secure system helps to protect data from unauthorized users, data masking and data encryption are preferred technology used by DBA to protect data.
...pt. That is however, not to say that it is without its problems, as previously discussed, it can possibly lead to a two tier system of reporting, despite reducing complexity its flexibility can limit comparability and place a heavy onus in terms of judgement of the preparer. Finally its simplifications may perhaps infringe upon the ease of which a private entity wishes to become public listed company. However, the disadvantages of adopting the standard are fat outweighed by the potential benefits it offers. As more time goes on, we will no doubt see more countries and companies adopting the standard. If capital providers (primarily banks) clearly understand and have confidence in the financial statements prepared under the guidance of the standard; then an SMEs ability to obtain the capital it need improves. Ultimately the economy in which it operates improves.

I do not know much what an input device is even I have been using computer for many years. I thought that an input device is just a component inside the computer. I also did not know the role of input device play. I am among those people who do not care much about the component inside the computer. Now as I reflect, seems like I have ignored the importance of an input device.
