basic manual tenth grade introducing database.

BASIC MANUAL FOR HANDLING DATABASE

DATABASE (DB)
DEFINITIÓN.
They are a set of data belonging to the same context (or common theme) and stored systematically (in an organized and classified) for later use.
•    Physical or static. They are tangible. A library can be considered a database composed mostly of documents and texts printed on paper and indexed (sorted) for consultation. Example: Dictionaries, Directories.

·          Due to technological development in fields such as computer and electronics, most of the databases are in digital format (e) as used to store customer information from banks, utilities, etc. users emails. Allow manipulation taking into account certain aspects of security and integrity of information.

APPLICATIONS BD.
Common applications are to manage customer information, services or products from companies and public institutions. They are also widely used in scientific environments in order to store the experimental data.
BASIC TASKS OF BD.
The tools for manipulating databases should basically allow: storage of data fields, data query and records, updating or amendment of records and disposal of these when they are obsolete.
TOOLS FOR WORK WITH BD.
There are programs called management systems databases, which allow the construction and administration of secure storage structures and comprehensive information. Examples are Managers: Oracle, Informix and Access (editor Microsoft databases)
OBJECTS (COMPONENTS) OF BD.

All BD manager should allow the design of four key items:

• Tables. They allow efficient storage of data within the database.
• Consultations. Allow to extract data stored in tables.
• Forms. They are the tool through which allows users to manipulate (insert, query, modify, delete data) the BD in a simple but safe.
• Reports. This tool allows you to generate reports printed or screen information database.


MS. ACCESS.

Manager is a database editor Microsoft office package, easy and intuitive handling in a graphical environment and tools similar to those used in other office suite applications.



MS. ACESS WINDOW ENVIRONMENT.

MS. ACCESS.  TOOLS BAR
Title Bar: This contains:
• Toolbar shortcuts: icons on the left side that allow the most common tasks of document editing: save, undo, repeat, print, preview, and an option to customize this bar.
• Name of the database and the program: in the middle of this bar allow the identification of the document.
• Icons minimize, restore and close: To manipulate the size of the program window.
File tab: Contains the options to save, open, insert, print and publish documents BD also provides access to predesigned templates for new BD structures and a panel to store specified storage location and name of the database.
Home Tab. Contains options for formatting the data stored in the database.
Create tab: Contains the options to insert objects (Tables, Queries, Forms, Reports) that allow you to manipulate the database information.
External Data tab: Contains the options to import or export information and BD components.
Tab Tools Database: Contains tools for structuring options Advanced mode the BD.


TOOLS FOR MANAGEMENT AND DATABASE DESIGN
In Ms. Access objects (tables, queries, forms, and reports) of the database can be constructed from the create tab. This tab provides different options organized into boxes to give the designer the construction of the objects according to the specific requirements of the information to be systematized.
In the tab create find:
• Templates. They allow use examples in Access and art structures.
• Assistants. That guide the designer step by step in building the database objects.
• design views. They allow designers to build and manually configure advanced cana one of the objects in the database
