  1. Skills Development MS Access Topic: Presented By: Tabreeq Khalid Presented To: Ma’am Iqra Malik
  2. Introduction • MS Access Data base management system which was launched by a Microsoft was a part the Microsoft suite and store data in its own form 13 NOV,1992 the first version of the micro soft was released • On 13 NOV,1992 the first version of the micro soft was released • Before Access was introduced, Borland and Fox were two Data base management systems which were dominating in the market
  3. It was windows first Mass market data Base program. Multiple changes were made in a program gradually Microsoft started releasing different version of MS Access .Each new version come with a modified RAM and storage device . The current version of MS Access which is being used required 2GB RAM and this memory requirement has been constant since 2000
  4. Definition • It is a Data Base Management system that combines the Relational Microsoft Jet Database Engine with a graphical user interface and software development tool.
  5. Uses • Manage accounts and Bills • Store data in he form of tables and edit or customize them later as per the requirement of user . • It can be used to make websites • Comapring data and finding a relationship between the existing data can be done using Access
  6. Types of data base in MS Access • There are two types of data base in MS Access 1 .Flat file database • When the data is stored in the of the plain text file and cannot incaporate multiple tables 2.Relational Data base . • When the data is stored in the form that the data items are related to one an other .It supports multiple tables and organize the text in rows and columns .
  7. Benefits • Easy to create Data base in a lesser time duration. • Used a very comprehensive programming language which made it user friendly . • With each revised version new options and features were made available to the user for their convience. • It is easy to install . • It is easy to import the data . • Graphical user interface made it easy to use.
  8. Major Components of MS Access • Tables • Queries • Modules • Relationship • Form • Macros • Reports
  9. Tables • Tables are essential objects in a database because they hold all the information or data. For example, a database for a business can have a Contacts table that stores the names of their suppliers, e- mail addresses, and telephone numbers. .
  10. Queries • Data is generally done through a query, because we would query the data so, we want to create our first-ever query. We go to the create ribbon here on the top toolbar. • What Are the Uses of Microsoft Access Queries? • We have a choice of four types of query; Simple Query, cross tab query, defined duplicates query, and defined unmatched query.
  11. Forms • A form in Access is a database object that you can use to create a user interface for a database application. A "bound" form is one that is directly connected to a data source such as a table or query, and can be used to enter, edit, or display data from that data source. Alternatively, you can create an "unbound" form that does not link directly to a data source, but which still contains command buttons, labels, or other controls that you need to operate your application.
  12. Modules • Modules, like macros, are objects you can use to add functionality to your database. Whereas you create macros in Access by choosing from a list of macro actions, you write modules in the Visual Basic for Applications (VBA) programming language. A module is a collection of declarations, statements, and procedures that are stored together as a unit. A module can be either a class module or a standard module.
  13. 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.
  14. Relationship • Introduction • After you have created a table for each subject in your database, you have to give Access a way to bring that information back together again when needed: Types of table There are four types of table relationships in Access. • A one-to-many relationship • A one-to-one relationship • A many-to-many relationship • A many-to-one
  15. 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?“. • A report can be run at any time, and will always reflect the current data in the database.
