Microsoft Access database application has a big choice of very powerful tools and objects that can help you create a simple database or a more complex version with multiple users. There are administrative tools of different levels such as database splitter, Access security module, relationship window, linked manager tool and many more.
Beginners see Access as something overwhelming, because of so many tools and objects. And everyone should start learning Access database with terminology.
Let’s start with the definition of a database.Database is collected and organized data, which makes it easy to access and display the information in different ways. Databases are great to store information and they are used in many cases in our life. A telephone directory, music library or mailing catalogues are all the examples of database. Access database is a collection of different information sets known as tables and that are related and linked together. The ability to link and relate the tables is what makes Access more flexible in reporting and adds functionality to this application.
There is also a primary key in Access database. You can assign a field in a table to be a primary key, which is recommended. The assigned field will act as the one responsible for joining other related tables. The field should be unique, required and preventing any duplicate data to be stored.
The dynasets or recordsets are the results of gathered records from the required tables and which are typically produced by queries. Query is probably the most important object in the Access database for us. These objects basically answer our questions. If you need to make a report, you don’t want to use all the data, but you should narrow down the criteria asking the question you need to answer and produce the recordsets. So, the above information covers the essentials of the data processing terms and several objects. This represents the back-end part of the database.
There is also a front-end part of Access database and you can start learning it with creating the screens called forms. Form points out to a query or a table and provides recordsets for us to view.
Reports are based on tables or queries and are in read mode only, previewing before printing. This object is a choice for document demonstration and doesn’t need additional software. While designing database objects, you will also encounter many components such as text boxes, combo boxes, labels and others. Each of them also have their own properties, which may change the look and behavior of the components.
These are only some of the terms you will need when dealing with Access database. It should make you little less confused while learning Access and help you design your database successfully in future.
