1. Differentiate Between Database Management System And Information Retrieval System By Focusing On Their Functionalities.

Database Management System
According to Modern Database Management eight edition, by Jeffrey A. Hoffer, Mary B. Prescott and Fred R. McFadden database management system (DBMS) is define as a software system that is used to create, maintain, and provide controlled access to user databases.

Support Concurrent Updates
Concurrent updates occur when various users make updates to the database at the same time. Supporting concurrent updates is also critical to database management as this component ensures that updates are made appropriately and the end result is precise. Without DBMS interference important data could be lost and or imprecise data stored.
DBMS uses features to bear concurrent updates such as batch processing, locking, two-phase locking, and time stamping to help make certain that updates are done correctly. Again, the user is not alert all this is incident as it is the database management system’s liability to make sure all updates are stored appropriately

Recovery of Data
In the event a misfortune occurs, DBMS must offer ways to pull through a database so that data is not eternally lost. There are times computers may break down, a fire or other natural disaster may occur, or a user may enter inaccurate information invalidating or making records conflicting
If the database is cracked or spoiled in any way, the DBMS must be able to recover the correct state of the database, and this process is called Recovery. The easiest way to do this is to make standard backups of information. This can be done at a set controlled time so in the event a catastrophe occurs, the database can be restored to the state that it was last at prior to backup.

Security
Security is the avoidance of illegal users accessing the database. DBMS uses features such as encryption, authentication, authorization and views to provide security to the database. Encryption is when DBMS converts the data in a database to an unreadable format. No illegal person trying to access this information will be able to read it. Authorized users will be able to see it in normal form.
Authentication is a technique in which the database officer can identify the person accessing the database. Authorized users are given passwords and successful entry of a legitimate password will allow the user entry into the database, if a password is not effectively entered, the user will be denied access. Authorization is a set of rules that the database administrator (DBA) sets up to specify levels of practice that individuals or groups are allowed to have.

    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.

    Network databases share several problems with the hierarchical database management system. Both are the very inflexible, and also set relationships and record the structures that must be predefined. The major disadvantage of both network and hierarchical database management systems was that they are the programmer’s domains. To answer the simplest query of this database, one had to create the program that navigated the database management structure and produce an output; unlike SQL, this program was written in the procedural, and required the great deal of the knowledge of both database management structure and underlying the operating system. As a result, these type of programs were not portable and took enormous amount of time to write.

    DBA deals with all of this by finding user needs, set the database, and test the system. DBA should enable editing any system he or she created. At the same time DBA should ensure the security of the data and guarantee data integrity and backup. Moreover, DBAs should know the database management systems (DBMS) that include the knowledge of Oracle, IBM DB2, and Microsoft SQL server (“Database Administrator,” 2010). Oracle is one of the most important platforms that DBA must know and have experience with. According to Kanaracus “The database experience we look for most of the time is Oracle”, says Tom Hart, executive vice president of the operations and technology group at Veritude. “SQL Server is more of a nice-to-have"

    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.

  • Difference Between Database System and Information Retrieval System

    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.

Data can be a customer's information, intellectual property, financial asset or any number of other records that can be maintained and managed on a system. Without Database security people are at risk of identity fraud, theft, destruction of property and much worse.

    Database Concepts, what are Databases all about? I am writing this paper to answer a few questions as part of my first assignment in a class designed to provide a better understanding of Database Concepts. There are many different types of databases, different implementations of databases, and different database software applications. So how does all this database stuff work? I have worked with databases for most of my professional career at many different levels. Sometimes as the user, entering data, retrieving information, and compiling reports. I have also provided service and support to help maintain a database system. More recently I perform both types of tasks. I have never stopped to think about what was really going on the background when I was using these systems. I aim to learn more about what databases are and how they function.

    The DBMS has a function that can be differentiate from the information retrieval system. The DBMS have the ability to store, update and retrieve the data. This is the main function of the DBMS because the database can be used if there is any record is being stored into the database. The record need to be retrieve first, then it can be change by the database administrator as it will be the record has been updated. The DBMS will protect the structure of the data structure.

    Computer software is always evolving and getting better. It is essential that a DBA have the most updated software to make-work easier. Another part of the job is planning future storage requirements for the database system’s hardware. Since new data is always being entered, eventually you will need a bigger database, which means you will need a bigger computer to hold the data. DBAs also will have to modify the databases if a new category of information needs to be recorded. And the most important duty of a DBA is protecting the data. Security is of paramount importance for a database administrator. Hackers will go to extreme lengths to breach private information. Part of security involves controlling and monitoring use access on the database, as well as periodically backing up the database’s information and offering technical support for customers having difficulty accessing data. A DBA must also be able to use the Oracle programming language to communicate with the computers he or she is working
