Database

Every application has many functions and its own. Therefore, the database software that comes with the Open Database Connectivity (ODBC) driver that allows the database to integrate with other databases. For example, a common SQL statements such as SELECT and ADD translated from proprietary syntax into the syntax of the program other database can understand. A database management system (DBMS) is a collection of programs that enables us to store, modify, and extract information from the database. There are many different types of DBMSs, ranging from small systems that run on personal computers and then to a large system that runs on the mainframe.

The DBMS must allow users to create database definitions • Data Manipulation Language as known as DML – to insert, update, delete, and query data in the database. • Concurrency control that is allows shared access to the database, with multip... ... middle of paper ... ...t, then the result will fast.

(Shelly, Cashman, Waggoner 1992). However, the arrival on the scene of the relational database along with the rapidly changing technology has modified the database administrator's role. This has required organizations to vary the way of handling database management. (Mullins 1995) Traditional database design and data access were complicated. The database administrator's job was to oversee any and all database-oriented tasks.

In addition, any changes made in database structure will be automatically recorded in the data dictionary, thereby freeing the users from having to modify all the programs that access the changed structure. Besides, the DBMS also functioning to create and manage the complex stru... ... middle of paper ... ...nvenient data point can be called as structured data. Non-structured data is definitely more interesting and archiving data. Some other examples of structured data including database, data warehouses and also enterprise system such as CRM and ERP while the other examples of unstructured data is the excel spreadsheet and RSS feeds. According to Robert Primer, the term structured data is generally applied to database while the unstructured data is applied to everything else.

For example we need to access our Database to update some information from it or just to extract it. Most of the businesses need a DB. They need to retrieve data in its complete form for further analysis or different objectives. Databases are needed to store our data being ready and available when required. b) DBMS (Crucial Concept): The DBMS would be responsible for all database activities (storage, retrieval, indexing, etc) and also be responsible for keeping a detailed description of the data being held.

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.

Database Report Introduction A database contains a collection of information organised in such a way that a computer program can quickly select pieces of data. You can think of a database as an electronic filing system. A field is a single piece of information; a record is one complete set of fields; and a file is a collection of records. For example, a telephone book is analogous to a file. It contains a list of records, each of which To access information from a database, you need a database management system.

This system often use in the library for searching books or in other department for use in searching data. Database management system often used in large company, however not only with large amount of data, a small amount of data can also be saved in database, which concludes that small company can also use this Database Management System. Commonly known application that implements the information retrieval system nowadays is a web based search website that everybody uses for example Google, Yahoo! Search, Bing and many more. Highlight the differences between data and information.

Answer Structured data is defined as a data that are record and being filed in the database to make it can be used efficiently. frequent the case with the selection of the type of detailed data structures should be used to allow efficient algorithms can be used. Good design data structure allows a variety of critical operations carried out by using the time and little memory space, as possible. structured data will be represent in discrete form which is in column and row form. this can make the data in the database more organized.
