Database Design Essay examples

Databases are the heart of the company. This is where all crucial company information is stored and can be accessed. Some databases are stored on site others in remote locations or using clouds. The information within a database can be manipulated in any way that the company needs it to be. Databases help to quickly search and retrieve information, it saves from data redundancy.

Second, Database is needed to take the collection of all sorts of sensitive data to organize, analyze, and extract data. It is the heart of many functions in today’s world. For example, when a password or user in a program it is checking the information type in against the information it stored in order to open the software. Databases solve most of the data management problems that are encountered.

Database System: A database system is an important part of an eCommerce website. The database is used to store information about the products for sale on the site. The database will hold information such as store pricing, descriptions, images and other details. In addition to this the customers details are

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

Web applications use a three-tiered architecture: The first tier is the Client Browser application, the second tier is a Web Server, and the third tier is a ________ .

Servers have better control access and resources to ensure that only authorized clients can access or manipulate data and server updates are administered effectively.

at a time,they are commonly connected to a LAN and run multiuser operating system.The resources which has to be managed

In a client and server caches, an each server cache is managed in one distributed system tier by a number of server members, usually cache server processes. In a separate tier, clients maintain their own caches that automatically call upon the server side to set off cache to update the server with client updates. In addition, the clients can member to server events using both data key specifications and queries. The client/server topology can be extended to any number of tiers.

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.

An operating system is the software that supports a computer’s basic functions, such as planning tasks, performing applications, and controlling peripherals. When choosing and introducing the best system for a business such as this, it’s important to make sure it fits the needs of the business while being easy to install, set up, manage, and understand. For this reason, I decided that the Apple OS X Server would be a good choice for this business. The OS X Server allows for more power, governing, and alliance throughout an organization.

The Profile Manager feature easily creates profiles to set up user accounts for mail, contacts, calendars, and messages. It also enforces constraints and password guidelines. Another feature, the Caching Server, speeds up the download and delivery of software quickly and safely. With these features, and many others, setting up and

I have chosen the three-tier design, the user interface runs on the client and the data is stored on the server. A three-tier design also has a middle layer between the client and server that processes the client requests and translates them into data access commands (Shelly-Rosenblatt, 2012).

When user has to use more than one infrastructure user need to pay more money for each cloud to use the facilities which makes the application expensive. [3]

Three types of maintenance plans include: preventative, corrective, and adaptive maintenance which improve the data quality. Activities to improve data quality include database backups, integrity checks, optimizing the index. Preventative maintenance incorporates creating and continuously maintaining daily and/or weekly backups for data loss prevention, corrective maintenance ensures system errors are corrected. One activity associated to corrective maintenance includes resolving deadlocks, which occurs when two or more tasks permanently block each other. Adaptive maintenance includes enhancing system and database performance via based on utility assessments and optimized queries to improve performance. (Coronel, Morris, & Rob., 2013).

(2) Utility Computing - offers storage and virtual servers that an organization can access on demand.

According to Rouse (2006), “Computer databases typically contain aggregations of data records or files, such as sales transactions, product catalogs and inventories, and customer profiles” (Rouse, 2006). Databases can hold a sufficient of information that are deemed
