Definition

Ms Access is a part of Ms Office which is used to keep the record of the personal as well as business data with the extension of

.MDB

A relational database running under Microsoft Windows. Data is stored as a number of " tables .Each table consists of a number of " records " and each record contains a number of " fields ", e.g. "Product code", "Supplier", "Quantity in stock". Access allows the user to create " forms " and "reports". A form shows one record in a user-designed format and allows the user to step through records one at a time. A report shows selected records in a user-designed format, possibly grouped into sections with different kinds of total (including sum, minimum, maximum average). There are also facilities to use links (" joins ") between tables which share a common field and to filter records according to certain

criteria or search for particular field values .

Uses of Data Base:

- Personal applications

- Small-business applications- Departmental applications- Corporation-wide applications - Web applications

ImportanceMicrosoft Access is an important information management tool that allows users to create databases to store various kinds of information for reference, reporting and analysis. It is a flexible program that allows the performance of simple end-user tasks as well as mission critical

operations.

Microsoft Access users can create tables, queries, forms and reports, and connect them together with macros. Advanced users can use programming language and its associated integrated development environment to write rich solutions with user control

and advanced data manipulation.

Key Terms Database management system (DBMS) A DBMS is an application that you use to manage a database. DatabaseA database is a collection of related data that is organized so that you can easily view the data and perform operations on the data. This article defines various database objects and database object views.

RelationshipA relationship is an association between Access tables or queries that use related fields.Data type

A data type determines the type of data that the field can store. Jet data types include the

following :TextNumberDate/TimeCurrencyAutoNumberYes/No

QueryA query is an instruction to retrieve information that is in a set of rows. You can use a query to retrieve information from a single table or from multiple tables based on specific criteria. You can also use a query to modify the information that you retrieved.Select queryA select query retrieves information that you want from one or more tables in a database. Then, the select query presents the information that you retrieved in a format that you want. You can also use a select query to group records and to calculate sums counts, averages, and other types of mathematical values.

Parameter queryA parameter query retrieves information in an interactive manner. You specify the information that you want by providing specific criteria. You can use a parameter query to extend the flexibility of other query types. Action queryAn action query performs an action on data in a table. You can use an action query to insert new records, to update existing records, or to delete existing records.

ControlA control is an object on a form, on a report, or on a data access page. You can use a control to display data, to perform actions, or to enhance the representation of data. For example, you can use a text box on a form, on a report, or on a data access page to display data. You can also use a command button on a form to open another form or a report. You can organize or separate the controls in a form by using lines or rectangles.

Record A complete set of all of the data about one person, place , event, or idea. Primary key The field that makes each record in a table unique . Foreign Key A field in one table that also is stored in a different table as a primary key . Report A printed document that displays information professionally from a database

One-to-Many Relationship Exists when each record in the first table may match one,more than one, or no records in the second table. Cascades Permit data changes to travel from one table to another .Cascade Delete Searches the database and deletes all of the related record. PivotTable View Provides a convenient way to summarize and organize .data about groups of records
