Analysis of Database Management and Information Retrieval Systems

Data objects can model relational data or advanced data types such as graphics, movies, and audio. Smalltalk, C++, Java, and others are objects used in object-oriented data. The object-relational is a combination of relational and object-oriented databases. Traditional and advanced data types can be used to construct database management systems. These systems can connect to a company’s website and update records as needed. Database Approach The main purpose of a database is data storage that can be stored and retrieved when needed. A popular common language called structured query language (SQL) is used to store and retrieve data in relational database. This language enables the systems to run a report or modify data or remove the data from the database. A database management system (DBMS) controls all aspects of a database, this is not limited to the creation, maintenance, and use of database. The DBMS ensures proper applications are able to access the database. An important purpose of a DBMS is to maintain the data definitions (data dictionary) for all the data elements in the database. It also enforces data integrity and security measures. Data Models Data models provide a contextual framework and graphical representation that aid in the definition of data elements. In a relational database, the data model lays the foundation for the database and identifies important entities,

Data Definition Language (DDL) statements are used to define the database design or schema while Data Manipulation Language (DML) statements are used to manage data with Schema objects.

This model demonstrates the data attributes logical entities and relationships between these entities within a business function. It also helps to create the physical data model. Moreover, it shows more details while integrate business logic and business rules. This model is used to describe the domain concept and their relationship of the domain problem.

The purpose of information retrieval is to provide quality service for the right person at the right time, with all the required information in hand. Only if data is stored in a procedural manner it can be easily retrieved. Information might be retrieved for marketing purposes, for

A data model is a conceptual representation of the data structures that are required by a database [Mamčenko, J. (n.d.)]. The data structures gives the information about data objects, associations between data objects, and the rules which administer actions on the objects. A data model serves as a bridge between the concepts of the real world and how the data is physically organized in the actual database. Data modelling has been ongoing for many years but still businesses struggle to extract the value from their data and thus, create well designed, intuitive models [Data Modeling Best Practices. (n.d.).]. With businesses considering for innovative ways

Information system is not just technology (conveyor systems, hardware and software), but it also includes the subsystems data, people, and procedures. Describe how Amazon leverages different technology for the two processes shown below (include at least two subsystems in each process)?

Through the use of a query, a database pulls up the relevant item that may provide solution to your query. The function that it uses to do so is called a

When determining the appropriate hardware components of new information system, what role must the user of the system play?

A processor capable of processing data at high speed, as well as, a sizeable memory are the prerequisites which are required in order to execute the DBMS software. this implies that one has to upgrade the hardware used currently at use for file-based system. in a similar fashion, DBMS

Big data is a vast amount of information, both structured and unstructured, unstructured is information that is not simple to interpret by traditional databases and structured information is the opposite, which is not too difficult to interpret data made form text or image. Structured or unstructured, the main business of big data is categorized

What is information retrieval system? Informational Retrieval System is the activity of obtaining information resources relevant to an information need from a collection of information resources. Web search engines are the most visible. Search can be based on metadata or on full-text (or other content-based) indexing. Automated information retrieval systems are used to reduce what has been called "information overload". Many universities and public libraries use IR systems to provide access to books, journals and other documents.

INPUT: It gather data 's from the environment to the system and is process to output.

The database means we collect data according to their types or relations and store these data in the tables in order to make further operated.  And the Database-management system is usually seen as DBMS which is software application used to manage these databases. What we discuss here is mainly focus on the DBMS.

3. End users: - End Users are the persons, whose jobs require access to the database for quering, updating, and generating reports. 4. System Analysts and Application Programmers: - Systems analysts determine the requirements of end users, and develop specifications for canned transactions that meet these requirements. DATA MODELS: - The structure of a database is the concept of a data model, a collection of conceptual tools for describing data, data relationships, data semantics and consistency constraints. 1. Network data Model 2. Hierarchical data model 3. Relation data model Network data model: - data in the network model are represented by collection of records and relationships among data are represented ny links. The links can be
