- 2. 2 Introduction What’s Access? We know that MS-office is application suite. One of the application in such application suite is MS- access. Access is a relational database application designed to handle thousand or a few records depending upon the user needs. by Nithin Raj
- 3. 3 Introduction Database tables are collections or lists of records, each record holding individual pieces of information in fields As a database Management System (DBMS), Access enables a user to create and maintain these tables, employing sophisticated, yet easy-to-use, tools to facilitate defining, constructing, and manipulating data by Nithin Raj
- 4. 4 Getting Started … In Access, a database application is composed of database objects, which are: Tables Forms Queries Reports Pages Macros Modules by Nithin Raj
- 5. 5 Tables Design a table:(before don’t forget to create access database file) You can add individual fields to a blank table structure using the panes in Table Design View The top pane is the grid and is used to specify a field’s name, descriptive text, and data type. The bottom pane is the field properties section and is used to specify field size and other attributes Each row in the grid corresponds to one field; a collection of all fields is grouped into a record Access denotes that one field in every table contains unique entries that distinguish that record from others, this is the primary key field. by Nithin Raj
- 6. 6 Tables Design a table: Within each field, there are three corresponding columns in the grid: The first is the field name column, which defines the name of the field The second is the data type column, which regulates what type of data a field can hold, such as numbers, text, and dates The third column is the description; information in the description column appears in the status bar when the field is selected in either a form or datasheet view Field names appear as column headers in Table Datasheet View by Nithin Raj
- 7. 7 Tables Design a table: Access data types are: AutoNumber Date/Time Currency Text Memo Number Yes/No OLE Hyperlink Lookup Wizard by Nithin Raj
- 8. 8 Tables Enter & delete data: Creating a database table is a two-part process; the first part defines the structure of the table. The second part of the process involves input from the user; this usually demands physically typing the data into the table Data can be entered directly into a database table using the table’s datasheet view When you advance to a previous or new blank row, Access writes the data to the table by Nithin Raj
- 9. 9 Tables Filter & sort tables: Records display in the order in which they were created by default Access provides sorting and filtering features to assist you in organizing and delineating table data as the number of records increases Records can be sorted in either ascending (low to high) or descending (high to low) order based on a selected field Filtering data involves specifying conditions that a record must meet to be selected. Filters can contain single or multiple conditions (tests) that must be met for a record to be listed. A set of records produced as a result of a filter is known as a dynaset You can apply two or more filters to the same table; in such case logical conditions such as AND or OR are used by Nithin Raj
- 10. 10 Forms Forms provide a user interface for database tables. They are used as the primary method of entering, editing, and displaying data contained in database tables While you can use the datasheet to perform many of the same functions,forms present information in an organized manner, thus enhancing data entry Forms are generally layout documents that combine graphic objects and table data by Nithin Raj
- 11. 11 Forms Access supports three primary views for working with forms: Form Design View, where the controls and layout can be modified, but the table data is not displayed Form View, where controls linked to table fields display the field’s value for the current record Datasheet View, where you can work directly with the table used by the form by Nithin Raj
- 12. 12 Forms Use a Form Wizard The Form Wizard can assist you in constructing basic form layouts. Instead of constructing a form manually, you can use the Form Wizard to quickly produce a basic form layout The Form Wizard prompts you for necessary information to construct a form according to one of several predefined layout types. After answering each question, you can advance to the next window or return to previous windows to select different options The Form Wizard allows you to define the underlying table(s), field inclusion, and basic layout schemes. You can quickly create and link controls to an underlying table(s) If necessary, you can later customize the form in Form Design View by Nithin Raj
- 13. 13 Reports A report is a design document that displays formatted data from one or more database tables. Reports are designed for printing and distribution to an audience Reports are used to summarize large quantities of data into meaningful information using calculations, record lists, totals, and other reports objects Reports produce paper forms such as invoices and inventory lists by Nithin Raj
- 14. 14 Reports Access provides several Report Wizards to assist you in the construction of reports. Report Wizards prompt you for basic information about the report, and then create a basic report layout Access permits you to view and modify the results of a Report Wizard just as you would do for an report created manually. You can use the tools supported by Report Design View to move, insert, and modify objects to customize the report by Nithin Raj
