1. Differentiate between database management system and information retrieval system by focusing on their functionalities.
Database management system Information retrieval
Database management system can provide access to all of the data, alleviating many of the problems associated with data file environment, and data can be shared among data users.
Information retrieval can provide the techniques of storing and recovering data and often disseminating Recorded Especially through the use of a computerized system storage techniques and recovery and often disseminate especially through the use of recorded computer data.
Types of database management system is centralized and distributed. A centralized database stores all related files in one physical and distributed is has complete copies of a database or portions a database. Types of retrieval they provide for users. Many previous attempts have been made to couple Database management system and Information Retrieval systems together, either by integrating the two into a unified framework.
Function of database management system can designed to manage data and information that large bodies within a company management involves both defining the structure Function of information retrieval a deals with various sources of information on the one hand and users’ requirements on the other. It must analyses the contents of the sources of information as well as the users’ queries and then matches these to retrieve those items that are relevant
Function of database management system can ensure the security of the information stored is not lost or compromised, despite system crashes or attempts for something that is not allowed. If data are to be shared among multiple users, the system must avoi...

The term is derived from a database technician cannot save data in a traditional schedule, and access data with SQL (Structured Query Language). Since the term in SQL is structured surgery, and the data cannot be retrieved from SQL, then those data must be unstructured clear.

problem and it will be used in this case to build the databases. The databases
There are two types of data. They are unstructured and multi-structured. Unstructured data comes from information that isn’t organized or easily interpreted by traditional databases or data models. This is usually in text format.
Most users will find what they are looking for the first times when conducting searches due to the database sufficiently being able to decode natural language. As users navigate through the website they will find many icons and tabs to help them through their searches. One does not have to be an expert to conduct searches using this database and will be able to use the simple search index to retrieve a desirable number of sources if the user knows exactly what they are trying to retrieve. This database would be an essential tool for students, teachers, or any patron to meet their informational
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.
Information Retrieval (IR) is to represent, retrieve from storage and organise the information. The information should be easily access. User will be more interested with easy access information. Information retrieval process is the skills of searching for documents, for information within documents and for metadata about documents, as well as that of searching relational databases and the World Wide Web. According to (Shing Ping Tucker, 2008), E-commerce is rapidly a growing segment in the internet.
Substantially, to fundamentally elucidate an information system, it is essentially a connected set of elements produced by people and managed through computers which allows the collection and distribution of data, to summarise the term it is generally a database. Data is a plural for datum which are elementary recognisable facts, information is datas that has been correlated so that context is formulated. To interpret data security, it is an assortment of facts which is translated to information secure on an encrypted server due to its personal state. In addition, the majority of security systems within modern technology are encrypted with pass-codes. However, database management systems (DBMS) can be breached in several ways including weak
These structures could look similar to a relational database, but others look completely different. Depending on the specific structure used, your choice of Database Management Systems will change as well. There are four common data models to use: Key/Value Stores, Document Databases, Table-Style Databases, and Graph Databases (Data Access for Highly Scalable Solutions). Key Value Stores Looking at the different data storage models, this is the most simple to implement. This is a way to have a schema-less design for storing data.
Data management is the process of managing information through designs and policies of an organization (Rouse, M., 2010). Data managers have to make sure that their organization is in compliance with regulations at all times. Data management can be effective if the organization do the following: 1) Every individual is assigned his or her on responsibility, 2) Determine how the data will be stored and backed up, 3) Implement a data management plan, and 4) Determine how data will be modified (Penn State, n.d.). Knowing who is involved and what their job is with the data is essential for an organization in order to manage data. When managing data you have to know how it will be stored and backed up in order to access the data effectively. You can not manage data without having an effective management plan to show you how to manage the data in your particular organization. Also, if you are managing the data you have to be able to know how the data will and when it will be modified. Managing data can be tricky, especially now that there are lots of laws that an organization must be in compliance with.
According to research, the people accountable for managing an organization’s database are called database administrators. The importance of a database administrator in a society should not be overlooked or treated with levity because they are fully in charge of data’s and information. Some of the examples of popular database management systems are My SQL, Oracle, etc. One of the major roles of a database administrator is to ensure database security. He or she is in charge of fixing security issues and complications that could
Inconsistently storing organization data creates a lot of issues, a poor database design can cause security, integrity and normalization related issues. Majority of these issues are due to redundancy and weak data integrity and irregular storage, it is an ongoing challenge for every organization and it is important for organization and DBA to build logical, conceptual and efficient design for database. In today’s complex database systems Normalization, Data Integrity and security plays a key role. Normalization as design approach helps to minimize data redundancy and optimizes data structure by systematically and properly placing data in to appropriate groupings, a successful normalize designed follows “First Normalization Flow”, “Second Normalization Flow” and “Third Normalization flow”. Data integrity helps to increase accuracy and consistency of data over its entire life cycle, it also help keep track of database objects and ensure that each object is created, formatted and maintained properly. It is critical aspect of database design which involves “Database Structure Integrity” and “Semantic data Integrity”. Database Security is another high priority and critical issue for every organization, data breaches continue to dominate business and IT, building a secure system is as much important like Normalization and Data Integrity. Secure system helps to protect data from unauthorized users, data masking and data encryption are preferred technology used by DBA to protect data.
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.
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:
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. It have the features which that can support the updates like batch processing, locking, two-phase locking and the time stamping.
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.
