Differentiate between database management system and information retrieval system by focusing on their functionalities. Answer Database Management System A database management system (DBMS) is the main software tools of the database management approach because it controls the creation, maintenance and use of the databases of an organization and its end users. There are several functions that a DBMS performs to ensure data integrity and consistency of data in the database. There have ten function of database management system. there are data dictionary management, data storage management, data transformation and presentation, security management, multiuser access control, backup and recovery management, data integrity management, database access languages and application programming interfaces, database communication interfaces, and transaction management.
There is a database functionalities that perform consistency and efficiency of database. This function can be achieved by using the DBMS. First and foremost is DBMS as a data dictionary management that consist of definition for each data element and the relationship that been stored in a data dictionary. Means that all programs that access the data into database will work through the DBMS. The data dictionary will be used by DBMS to the require data component structure and its relationship.
b) DBMS (Crucial Concept): The DBMS would be responsible for all database activities (storage, retrieval, indexing, etc) and also be responsible for keeping a detailed description of the data being held. DBMS is a program that helps users to communicate with the Operating System through an interface in order to access the data from a Database in a friendly way and as soon as possible. It allows users to store retrieve and update information quick and productive. DBMS handle to recover the database in case of system error and needs to have an organized system for security issues. c) Metadata – Data that Describes Data Metadata it’s all about data being held in a Database.
When decide to perform a DBMS in business, first we must decide what type of DBMS we want. These are the ability to update and get back the data, Support Concurrent Updates, Recovery of Data, Security, ... ... middle of paper ... ...sorts of files may have an internal structure, they are still considered "unstructured" because the data they contain in order in a database. Email is an example of unstructured data, because while the busy inbox of a corporate human resources manager might be arranged by date, time or size, if it were truly fully structured, it would also be arranged by exact subject and content, with no difference or spread which is not practical, because people do not generally speak about precisely one subject even in focused emails. Conclusion is, structured data and unstructured data have the own characteristic and benefits. We as a user must know to handling the both of integration into a database.
It also contains great security because of the object based security model. MySQL MySQL is an open source relational database management system.

It is a full-featured database primarily designed to compete against competitors Oracle Database and MySQL. Some benefits to using SQL server are the seamless navigation which gives enough support for users to know how to work the system without asking an expert for assistance, it includes a query editor which is a tool used for executing T-SQL quires, which comes with the three features which support the database; Estimated Execution plan, Actual execution plan and Client Statistics.
Data is often stored in separate systems, sometimes making it difficult to obtain certain pieces of information. In order to retrieve data from a database, one has to use a database management system (DBMS). The database management systems are designed applications that interact with the user, other applications, and the database itself to capture and analyze data. The DBMS is designed to allow the definition, creation, querying, update, and administration of databases (DifferenceBetween.info, 2014). The DBMS relieves the programmer or end user from the task of under- standing where and how the data are actually stored by separating the logical a... ... middle of paper ... ...smissions.
The DBMS will protect the structure of the data structure. Another function of the DBMS is the concurrency control services. Database Management System must ensure that the database is updated correctly because the database can be used by many multiple users. The DMS enable many user to access the data concurrently. The database managements system will help from ay data loss.
This would also improve the maintenance and management of the database servers. Regardless of the type of business, it is supported by a database or many databases. Even if the database is a paper based system of record, or it is organized by the most sophisticated, technically advanced software, it is a important fundamental piece of the business. Databases will continue to exist and expand as more companies become more of aware of the importance of record and data management.

Databases are made to operate all type of informations by storing, retrieving and managing that informations. Databases are made so that user can interact with databases itself. DBMS is usually responsible for mainting all the data in a system and if that data lost then DBMS will restore the data itself.

Data provisioning receives, stores, and manages all validated transaction data from transaction processing. It also provides data back to transaction processing and information-to-information delivery when requested. Data dictionary and data catalog keep way of what data exists, where it is stored, what it means, and who has authority to access it. That helps data provisioning to protect the data and to provide access to data and information to those who need it. Data provisioning stores the organizational structure regulations in tables in its database, so these regulations can be changed without any difficulties when management decides to modify the organization.
