Description Of A Database Management System

A database is a structural set of related data that is organized in such a way that the information can be easily managed, accessed, and updated. The purpose of a database is to replace paper documents, files, and filing cabinets. The data collected in databases is an efficient way to store, retrieve, and analyze the information.

is essential to achieve the goals that where outlined when the database was first planned.

A Relational Database Management System (RDBMS) is a type of database management system that stores data in the form of related tables. The system does not require many assumptions about how data is related t or how it is to be extracted from the database. The database can be viewed in several forms.

Database, it is a place use to store lots of data. It can be seen as a filing cabinet. And database management system (DBMS) is software that specificity designs for managing the data in database such as create, update or delete them. General is including security, retrieval and backup features. User also allows using the data to create a report or share data with multi-user.

Databases management systems – special software to create and maintain a database and enable individual business applications to extract the data they need without having to create separate files or data definitions in their computer programs.

A database is used to store collections of information and easily retrieved at a later date. The larger the amount of information, the more organized a database needs to be. A database is created with the requirements and needs of current and future users and most importantly, with past users and their information. Out book defines database systems as “an organization of components that define and regulate the collection, storage, management, and use of data within a database environment”. (Database Systems, 2013)

Relational Database Management System is a database where data is represented as a set of relations in which data is stored. RDBSM is the basic for SQL. RDBSM contains a table (Is where the data of RDBMS is stored in) and the table contains a field (It is the smaller pieces of the table/ attributes of the table.), records (Also known as a row. It is a single entry in the table. It lies horizontally on the table) and columns (Columns lie vertical on the table. It contains all of the information related to a single field/ attribute). Constraints (Rules) can be enforced on a RDBSM. Example: Unique constraint (To ensure that all the data in a column is of different values), Not Null constraints (Set in place to ensure that a columns cannot have a null value), Primary key (Ensures uniquely identified records in a table), Foreign key (Ensures that

When selecting a new database management system, determine if the vendor offers auditing, reporting and data management tools. In addition, the software should provide application level security and interface to the organization 's corporate-wide procedures for granting access to systems. For example, authentication should allow a secure protocol, such as Secure Sockets Layer (SSL). In addition, data may need to be encrypted to ensure additional protection. Application security gateways and database firewalls understand the application and track user access. Deep packet inspection examines each packet going over the network to the database server to determine the type of access being attempted. Application security gateways can provide

A foreign key is a column in a database that links data between tables by cross referencing because it references primary keys from other tables. For example if there are two tables, customer and order then a

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.

A database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images.

Database management system software (DBMS) is the software that can operate on the front and back end of an organization’s database. As do the database requirements of an organization differ, so do the types of DBMS software. The type of DBMS software required can often be narrowed down to the organization’s size and industry (Mohamed 2016). Currently, the top three DBMSs are Oracle, MySQL, and Microsoft SQL Server (“Microsoft SQL Server vs. MySQL vs. Oracle Comparison” 2016). Each having its own forte; however, in this assessment, only MySQL and Microsoft SQL Server (MS SQL Server) will by compared and contrasted to one another in the aspects of an organization’s needs, the hardware requirements, and the database

DBMS: The collection of programs that manages the database structure and controls access to the data stored in the database. The DBMS serves as the intermediary between the user and the database. The database structure itself is stored as a collection of files, and the only way to access the data in those files is through the DBMS. The DBMS presents the end user (or application program) with a single, integrated view of the data in the database. The DBMS receives all application requests and translates them into the complex operations required to fulfill those requests. The DBMS hides much of the database’s internal complexity from the application programs and users. The application program might be written by a programmer using a programming language, such as Virtual Basic.NET, Java, or C#, or it might be created through a DBMS utility program. The benefits of employing a DBMS are improved data sharing, improved data security, better data integration, minimized data inconsistency, improved data access, improved decision making and increased end-user productivity (Coronel & Morris, 2015).
