Introduction to Databases

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,

A database administration framework (DBMS) is a PC programming application that connects with the client, different applications, and the database itself to catch and dissect information. A universally useful DBMS is intended to permit the definition, creation, questioning, upgrade, and organization of databases.

* Describe the role of databases and database management systems in managing organizational data and information.

This must be in your own words and not copied and pasted from the original source. Include the purpose of the database and the subject matter it covers. This may be four or five sentences; and

Learning Outcome 6.2: Describe a database, a database management system, and the relational database model.

A Database Management System or (DBMS) is an essential tool for any organization or company in today’s modern world. A DBMS is “a group of programs that manipulate the database and provide an interface between the database and its users and other application programs” (Stair & Reynolds, 2011, p. 189). So in choosing the right DBMS there are many factoring issues with choosing the right one for the company or organization. When choosing a DBMS one has to think about how the system will ultimately help the company or organization with day to day processes and the goals of the company or organization.

Individual Database Design Paper Write a 350- to 700-word paper in which you do the following: • • Explain what database systems are and how they are used. Define database architecture. Consider Microsoft Access , ® ® ® ® Microsoft SQL Server , Oracle , and IBM DB2 software as possible examples. Summarize your paper by describing the database systems in your workplace, identifying which database systems and architecture they fall under.

Figure 11 shows the relationship of a database using DBMS, connecting the user with the information from the database. A database consists of many data from customers to orders, services, employees, and so on. The user can be a customer or employee. Employees use DBMS to find customer’s information, service types, and service provider information. Later in the process, the DBMS will then extract data from the database to answer the users’ questions.

Database Processing: is the system of collecting, storing, and processing data for the purpose of gathering information, managing information, and creating new knowledge from the stored data. Database Management Systems: Data processing in business is most often done using Database Management Systems (DBMS). A DBMS is used to create, process, and maintain a database. Some common inputs and outputs of a DBMS include; tables and forms to input data, queries to retrieve data, and reports to output and present data. Enterprise Database Managements Systems: this is a database system that supports a multi-user environment. These are most often used in large businesses that require employees to input and process data using a variety of different applications. Common enterprise technologies

Give three examples of where you could seek help from to overcome database design or operational problems.

Database system design can be extremely time-consuming as it takes sophisticated software to create and control it. The design process becomes less user-friendly as it takes a more extensive knowledge of how to use it. The standard of an excellent database is one, which is complete, integral, simple, understandable, flexible and

Write and describe a variety uses organisations make of use of databases and the issues they face - P1.1

This paper will compare and contrast five different database management systems on six criteria. The database management systems (DBMS) that will be discussed are SQL Server 2000, Access, MySQL, DB2, and Oracle. The criteria that will be compared are the systems’ functionality, the requirements that must be met to run the DBMS, the expansion capabilities – if it is able to expand to handle more data over time, the types of companies that typically use each one, the normal usage of the DBMS, and the costs associated with implementing the DBMS.

What is database management system? Database Management System is a database program. The DBMS manage incoming data, organize it, and provided ways for the data to be modified or extract by users or other programs. This cause, most database software comes with an Open Database Connectivity (ODBC) driver that allows the database to integrate with other databases. For example, common SQL statements such as SELECT and INSERT are translated from a program's proprietary syntax into a syntax other databases can understand. Some DBMS examples include PostgreSQL, MySQL, SQL Server, Microsoft Access, Oracle, FileMaker, RDBMS, dBASE, Clipper, and FoxPro. It is a software system that uses a standard method of retrieving, and running queries on data.

DBMS enable many users to access shared data concurrently. Concurrent access is easy if all users are only reading data. But when multiple users are accessing the database simultaneously, the database may result in inconsistencies. DBMS can prevent this occur.
