Question 1
Database Management System (DBMS) is a program that use by one or more computer users for create and access data to in a database or a set of software tools that control access, organize, store up, handle, retrieve and to maintain data in a database. In practical use, the terms database has a database server, database system, data server, and database management systems are often used interchangeably.
Many several functions that a DBMS performs to make a guarantee the data integrity and consistency of data in the database. The ten functions has in the DBMS such as data dictionary management, data storage management, data conversion and presentation, safety management, multi-user access control, backup and revival management, data integrity management, database access languages and application programming interfaces, database communication interfaces, and transaction management.
Firstly, the function of DBMS is an update, storage of data and retrieve data. Whereas the data should be always bring up to date includes adding new records, changing and too deleting exist records. This certain function is used for the storage of data and any related data entry forms or screen definitions, report definitions, data validation rules, procedural...

... The rules of unstructured systems are fewer and less complex.
From the beginning, the world of structured systems and unstructured systems has grown separately and yet in a parallel. Therefore, it is no surprise that each environment is a separate and apart from the other in ways such as a technical, an organizational, a structural, and a functional.
See the possibilities, if the two worlds were able to be connected in an effective and meaningful way. Visualize the new types of systems that could be built and the development to existing systems. However, see the amazing benefits to be gained if the technical, organizational, structural and useful barriers were to the disappear.

This article deals with the topic of how organizations should go about implementing new technology systems. The article is built around Murphy's Law that, "Whatever can go wrong, will." When organizations implement new system a lot of know problems cannot be avoided and unforeseen problems arise with even grater frequency. Chew outlines seven points to help launch a new system with greater success since they are essential for long-term survival.
Information technology has advanced in multiple ways in society, where organizations has implement the structure into their work environment. Industries have outsource their manufacturing to other places in the world and rely on telecommunication to keep the marketing. The geographic distribution has changed significantly by reducing the distance it takes to complete an operation, due to information technology. These are just a couple of examples of how this advanced technology has reshape our society and continuing.
A database management system, or DBMS, gives the user access to their data and helps them transform the data into information. Such database management systems include dBase, Paradox, IMS, and Oracle. These systems allow users to create, update, and extract information from their databases. Compared to a manual filing system, the biggest advantages to a computerized database system are speed, accuracy, and accessibility.
For this coursework two kinds of data models can be used. The object oriented data model, Object Oriented Database Management System(OODBMS), or the relational data model, Relational Database Management System(RDBMS). The differences between these two models and the data model to be used are described in this chapter.
Databases and database systems have become an essential component of everyday life in modern society. Nowadays, they are as common as smart-phones. Everyday, most of us encounter several activities that involve some interaction with a database.
Relational database management systems are composed of objects or relations. They are managed by operations and governed by data integrity constraints.
The second different between DBMS and retrieval data is, database management system functions as a data dictionary management which means the place for DBMS to store the definition of data and their relations (metadata). DBMS use this function to
Normalization, Integrity and Security are the important role for a DBA, Normalization helps to avoid data redundancy by reviewing data base structure at certain level. It helps to build an effective data model. Data Integrity provide some level of assurance over the information getting store and retrieved from database, DBA has to understand all DBMS features use them correctly for Data Integrity. Data Security is toughest part for DBA, auditing and multiple level security can protect data but none of them provide complete security, security can also be managed by encrypting and masking the organization data.
RDBMS remains for Relational Database Management System. RDBMS information is organized in database tables, fields, and records. Each RDBMS table comprises of database table columns. Every database table line comprises of one or more database table fields. RDBMS store the information into the accumulation of tables, which may be connected by basic fields (database table sections). RDBMS additionally give social administrators to control the information put away into the database tables. Most RDBMS use SQL as database query language
Information Retrieval is simply a field concerned with organizing information. In other terms, IR is emphasizing the range of different materials that need to be searched. Others researcher said that IR is the contrast between the strong structure and typing a database system with the lack of structure in the objects typically searched in IR. The actual process in information retrieval systems is it has to deal with incomplete or under specified information in the form of the queries issued by users. IR uses the techniques of storing and recovering and often disseminating recorded data especially through the use of a computerized system.
Database systems play an important role in our daily lives, and the need to be used in various fields of life in the present day are
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
The database application design can be improved in a number of ways as described below:
Example of the non-structured data is an email and the word processing documents. An email is the message that being distributed into the recipients using an electronic. It is being sent from one computer user to another user. Example of the word processing documents is the Microsoft excel. It is spreadsheets that being produce by the Microsoft for calculating, graphic tools, pivot tables and a macro programming language. This is because the files may have internal structure but it is considered as the non-structured data because the data in the database is still unstructured.
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
