he Access object models are at the heart of using VBA in Access They distinguish programming in Access from programming in other VBA applications by providing additional commands to manipulate tables, queries, forms, and reports and by providing all the functionality that the user would normally obtain from the menu structure of Access For example, the object model in Microsoft Excel contains commands and objects specifically relating to workbooks and worksheets, giving you the means to manipulate ranges and cells In Access, several object models are used and the whole application is oriented toward a structure of tables, queries, forms, and reports The object model is written around this structure Access is effectively a three-tier application: the client services tier, the object model, and the data services layer The usual Access interface that you view is the client services tier and is the layer that normally communicates with the user Underneath this sits the various object models The important ones are Access, DAO (Data Access Objects), and ADO (ActiveX Data Objects) Each time you do something in your database, you are issuing commands through one of these object models For example, if you create a new query, the underlying code uses the QueryDefs collection and the QueryDef object in the DAO object model to hold the details of your query Similarly, you can use the CurrentDb object to obtain the file name (and path) of the database:

Using the object models and a programming language such as Visual Basic, it s not difficult to develop your own Access front end with exactly the same functionality as the Microsoft Access front end Every menu command and function key on the Microsoft Access l front end is represented within the object models This is not to say that these are the exact objects that Access uses itself, but Microsoft has empowered you with all the objects and methods for you to do anything in code that can be done from the Access menu, and as you will find out in the practical examples later in this book, a whole lot more besides Strangely enough, if you decided to write your own front end, there would be relatively little code to write because all the functionality is contained in the object model Below the object models sits the data services layer, which holds the data in the tables and is modified by commands from the object models The object models contain a large number of objects for example, CurrentDb, TablesDef, QueryDef, Forms, and Reports These objects are discrete entities that offer various pieces of data analysis functionality Most important, they can be controlled from your code When programming in Access using VBA, you use standard VBA commands and functions such as ForNext, IfThenElse, and MsgBox, but you use the object model to communicate with the Access application by manipulating the properties and methods of the various objects at your disposal, such as the TableDef object or the QueryDef object An object is a programming structure encapsulating both data and functionality that is defined and allocated as a single unit and for which the only public access is through the programming structure s interfaces An object is a part of the Access program The objects are arranged in a hierarchy For example, at the top of the Access object model is the Application object, which is Access itself For example, under the Application object is the CurrentDb object, and within the CurrentDb object are TableDef objects Within each TableDef object are Field objects, and so on Each object can contain settings, called properties, and actions that can be performed on the object, called methods For example, if you want to view or edit the SQL for a specific query, you can look at the SQL property of a particular query within the QueryDefs collection An example might be
