Forms

Forms allow you to create a user interface in which you can enter and edit your data. Forms often contain command buttons and other controls that perform various tasks. You can create a database without using forms by simply editing your data in the table datasheets. However, most database users prefer to use forms for viewing, entering, and editing data in the tables.

Macros

Macros in Access can be thought of as a simplified programming language which you can use to add functionality to your database. For example, you can attach a macro to a command button on a form so that the macro runs whenever the button is clicked. Macros contain actions that perform tasks, such as opening a report, running a query, or closing the database. Most database operations that you do manually can be automated by using macros, so they can be great time-saving devices.

Overview

This article provides a brief overview of databases — what they are, why you might want to use one, and what the different parts of a database do. The terminology is geared toward Microsoft Access databases, but the concepts apply to all database products.

Queries

Queries can perform many different functions in a database. Their most common function is to retrieve specific data from the tables. The data you want to see is usually spread across several tables, and queries allow you to view it in a single datasheet. Also, since you usually don't want to see all the records at once, queries let you add criteria to "filter" the data down to just the records you want.

Reports

Reports are what you use to format, summarize and present data. A report usually answers a specific question, such as "How much money did we receive from each customer this year?" or "What cities are our customers located in?" Each report can be formatted to present the information in the most readable way possible.

Tables

A database table is similar in appearance to a spreadsheet, in that data is stored in rows and columns. As a result, it is usually quite easy to import a spreadsheet into a database table. The main difference between storing your data in a spreadsheet and storing it in a database is in how the data is organized.

The parts of an Access database

The following sections are short descriptions of the parts of a typical Access database.

What are the basic concepts and features of DBMS?

The fundamental concepts and features of a DBMS include ,data models, query languages, file organization and indexing, normalization, candidate keys, and key fields

A data model is an abstract representation of a database system

What is a database management system?

A database management system (DBMS) is a software tool that enables users to manage a database easily

It allows users to access and interact with the underlying data in the database

These actions can range from simply querying data to defining database schemas that fundamentally affect the database structure

What is a database?

A database is a tool for collecting and organizing information. Databases can store information about people, products, orders, or anything else. Many databases start as a list in a word-processing program or spreadsheet. As the list grows bigger, redundancies and inconsistencies begin to appear in the data. The data becomes hard to understand in list form, and there are limited ways of searching or pulling subsets of data out for review. Once these problems start to appear, it's a good idea to transfer the data to a database created by a database management system (DBMS), such as Access.

What is a relational database management system (DBMS)?

Relational Database Management Systems are the most common type of DBMS

It stores data in the form of related tables and uses Structured Query Language (SQL) to manipulate and access data

Organizations use RDBMS to store large amounts of structured data, such as :,customer information or product inventory

What is the difference between a database and a DBMS?

You also have the Database Application

The application of a database can be either departmental or personal or may be for internal use in an organization

Then you have the DBMS, which we've been discussing

This is software that helps the users create the database and access the data inside it in an efficient manner

A technical data management system (TDMS) is a document management system (DMS) pertaining to the management of technical and engineering drawings and documents.
Often the data are contained in 'records' of various forms, such as on paper, microfilms or digital media.
Hence technical data management is also concerned with record management involving technical data.
Technical document management systems are used within large organisations with large scale projects involving engineering.
For example, a TDMS can be used for integrated steel plants (ISP), automobile factories, aero-space facilities, infrastructure companies, city corporations, research organisations, etc.
In such organisations, technical archives or technical documentation centres are created as central facilities for effective management of technical data and records.
