Evaluate The Usefulness And Ease Of Use Of Maintaining A Database

* Write clearly and concisely about relational database management systems using proper writing mechanics and technical style conventions.

The lab begins with a simple example of query development using Access; then, evolves to more complex queries which the student should perform after completing the first exercise. The student can create a query with the wizard, with query design view, or with SQL statements. The Northwind database will be used again in this lab.

A relational database is a database that consists of a collection of tables with columns showing entities, and rows showing data. This type of database uses a primary key and foreign key. The foreign key in another table will point to the primary key of a table, and this is how tables can relate to each other. This permits for one-to-one, one-to-many, and many-to-many relationship between the data. An advantage of relational databases includes the ease of adding or modifying new tables and entities without needing to change the structure of the database already in place. Relational database have many features, including indexing, setting data type, and setting validation tests, all these help to ensure data integrity.

Microsoft Access is not just a DBMS but it is a DBMS plus an application generator. Microsoft Access contains a DBMS engine that creates, processes, and administers the database and also contains form, report, and query components that are the Microsoft Access application generator.

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

Database interface's SQL editor provides an easy and efficient way to write and test scripts and queries. And its powerful data grid provides an easy way to view and edit data related to any DBMS/RDBMS tools.

33) A set of SQL statements stored in an application written in a standard programming language is called embedded SQL.

format and submit it to the course canvas. This covers SQL Part A (Chapters 2,8&

An ORDBMS is more advanced than a simple RDBMS since the user can also create reports.

It means structured query language. The SQL will allow access and maneuvering of databases. The purpose of SQL is that it’s a standard language to be used for

Firstly a relational database contains a set of tables which basically are linked collectively by the relationships between the tables. Also it is also known as reason such as a database is called relational database.

     There are different markets for the different classes of DBMS. Access databases and applications will be used company-wide in very small companies. These databases can be found in different departments of larger companies, but would not be used at a company level. MySQL, according to their website http://www.mysql.com, has over 6 million installations, including companies like Yahoo and the Associated Press. I think MySQL would be a good fit for a mid-sized company that cannot afford the price of the higher-end DBMS, but need more functionality, security, and robustness than is offered by Access. Finally, the large DBMS systems like SQL Server, Oracle, and DB2 are typically only utilized in large companies, because of the investment required to install and maintain these databases.

MySQL, designed and distributed by Oracle, is one of the most prevalent SQL database management systems presently available. The software is an open source version. In other words, it can be downloaded and used for free.

Data and Query model: a specific framework are used in SQL to store data, in addition data are access intelligently with a requisite set of query APIs.

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.
