Unit 17 - Database Design Concepts

* Describe the role of databases and database management systems in managing organizational data and information.

The first difference is that Microsoft SQL only used Windows as the only operating system while other three platforms can use multiple platforms. Developers do not have any operating options to choose since Microsoft SQL only supports for Windows. Therefore, they either have to switch their operating system to Windows or use Oracle, Terada, and DB2

Data confidentiality is one of the three main IT security components which are data confidentiality, integrity, and availability (CIA). To keep your data confidential means to protect your data from unauthorized access. In other words, sensitive data are stored in a protected system that keep these information and data away from attackers and here the data confidentiality will measure the ability of the system to protect its data.

Database, it is a place use to store lots of data. It can be seen as a filing cabinet. And database management system (DBMS) is software that specificity designs for managing the data in database such as create, update or delete them. General is including security, retrieval and backup features. User also allows using the data to create a report or share data with multi-user.

data and risks will help a company to design strong policies, procedures and standards that will help to keep data secure.

In moving forward, it is vital that data security is implemented at every step of the design phase to ensure the integrity of the data is maintained.

Why are databases important to business? How do databases generate sales and-or profits? What databases do you interact with, and how do they benefit you?

Data security is the responsibility of the information system team. Three responsibilities of this team are making sure the data is accurate, protecting the data from unauthorized users, and correcting the data if it is damaged. This includes protecting the system by firewalls, gouging phishing, and protecting data from a hardware or software loss.

(M3) & (M4) what do we mean by data integrity and security? Data is the most valuable commodity in a PC system. You need to plan and use procedures to enable the safe recovery of user data in the event of data loss during upgrading and also the safe recovery of the entire system in the event of catastrophic failure resulting from upgrading.

“The practice of keeping data protected from corruption and unauthorized access” is known as data security (SpamLaw, 2011). The focal point of data security is the protection of

Individual Database Design Paper Write a 350- to 700-word paper in which you do the following: • • Explain what database systems are and how they are used. Define database architecture. Consider Microsoft Access , ® ® ® ® Microsoft SQL Server , Oracle , and IBM DB2 software as possible examples. Summarize your paper by describing the database systems in your workplace, identifying which database systems and architecture they fall under.

Data can be characterized as helpful information for an examination, choice or undertaking. Data should dependably, be ensured legitimately, paying little respect to how it is put away, introduced, or imparted. The fundamental points of data security are to protect:

Information Security and the breaches are the major concerns for any organization. Maintaining the data safely against the unauthorized access, data loss and modification of data is very important. Because any organization runs on the credibility of the customers.

Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.

This paper will compare and contrast five different database management systems on six criteria. The database management systems (DBMS) that will be discussed are SQL Server 2000, Access, MySQL, DB2, and Oracle. The criteria that will be compared are the systems’ functionality, the requirements that must be met to run the DBMS, the expansion capabilities – if it is able to expand to handle more data over time, the types of companies that typically use each one, the normal usage of the DBMS, and the costs associated with implementing the DBMS.
