There are different objects in Microsoft Access database application and one of them is form. Forms are screens in Access, used for entering or displaying information stored in tables or used in queries. Forms can be made for reading information only, but usually they are used for typing the information in. even though there are many types of forms available now, two form types are more commonly used. They are the main form and sub form.

Only after you design your database and build relationships between tables, you can create forms. It is typical for main and sub form to model what is called one to many relationships. The main form would be responsible for one side of relationships and the sub form takes on the other sides of those relationships. For example, imagine that a customer has many orders. So, the main form would display one record of this customer and the sub form would show all the orders this customer has.

When sub forms are created in MS Access, it is typical to display them in grid format in order to show multiple records. This way it could display order 1, order2, etc. The sub form and the main form have to be linked, which is performed via primary key of the main form table and the foreign key of the sub form table. If you right click on the sub form, you will be able to see its properties such as link child and link master. The primary key will be shown in the link master and the foreign key will be at the link child property.

It is important to create relationships between tables correctly. Incorrect relationship will lead to bad functioning of the main and sub form.

You can also build multiple sub forms in Access, which are linked together, but it might get tricky. It is worth saying that deleting a record in the sub form will not change the record in the main form, if referential integrity has been enforced as well as cascading delete. But the reverse is not going to happen, so if removing record in the main form it will delete all related data in the sub form. It makes sense, because you don’t want to have any recorded orders, which have no linked customers to them. But, on the opposite, you might have a customer with no orders’ records.

MS Access sub forms are very useful for your database organization, because it helps you to show multiple records stored in the system. In the latest editions of Microsoft Access database, you can even make the color of the grid lines different, which will give your sub forms more professional look.

Microsoft Access database contains different objects. The objects are tables, forms, queries, reports, macros and modules. The least you need to create a database is a table. Tables hold all information you enter into your database. It is a kind of a container for your data. Each table will have columns with certain names like first name, last name, address, etc. Each table will also have a certain amount of rows. You might also have several tables in your database, depending on the amount of information you need to store. For example, in invoicing system, you might need one table for customer information and another table for sales information.

Table is probably the most important item of your database. It also has an index, which is used for easier searching. You can also link your tables using their key fields. You can view your table in datasheet view or design view. Datasheet view is used for entering data and design view is used for creating the table, setting the columns, indexes, etc.

Access form is the way to present data. We can use the form for entering, changing or removing the data from the database. Access forms are screens for typing the information into the tables and displaying data from them. Forms can be connected to a record source like a query or a table. It has to be bound if you want to save the data u enter into the form. There are controls in form like a text box for entering information. There is also a possibility to create a sub form within your main form. Usually a sub form is used to display multiple records. Forms can contain no data at all. Some might only have a few buttons, which will help navigate to other parts of the database. Sub forms are typically used in some of the relationship cases, such as when one client has many sales.

Another Access object is a query. This object asks your database different questions and provides you with answers. If will find the necessary information in the database based on what you ask. Query will give you the answer and you can create a report based on the received information. Queries are based on your tables and you can even combine the necessary tables when you run your query for obtaining the needed answers. You also have the opportunity to edit the information in your query and the table in question will change as well.

Report is the object used for output information. It is sent to the printer and you can base your report on the query or table.

Macros and modules are more complex objects of Access and they are not necessary for creating databases. You can build simple database and perform simple tasks with the above objects. But if you want to make the most out of your Access database and have more control over it, you should also learn macros and modules taking more advanced Access training.

MS Access is a relational database, which allows us to link tables via primary and foreign key. A primary key contains a unique value for every table record, such as an employee number. As for the foreign key, it exists in another table that is used to reference records in the main table. Both primary and foreign key must be defined by the same field size and data type. It might also be helpful to give the fields the same names, even though it is not necessary.

Primary key holds the vale only once, but foreign key can reference the value multiple times. So, a table with employee information will be referenced multiple times in another table, during the staff reviews every quarter. But this is only one type of relationship between tables. There are actually 3 types of Access table relationships.

The first type is one to one relationship, which occurs when you link two primary keys, so a record in one table has related record in another. The values of primary keys in both tables have to be alike for the relationship to work. You might consider splitting the employee data into several tables, because some information doesn’t need to be seen by other people besides certain staff members. And then, after splitting, you would link the two tables via this relationship.

The second type of relationship is one to many. This type is the most common and is often the first one to be explained. The training company, for example, would create a database with the records of all delegates stored in one table and courses records in another table. So, the table with courses will hold the foreign key for the records of the delegates, so they could be assigned for one or more classes. This kind of primary/foreign key relationship has unique value in the first table, which is referenced multiple times in the second table.

And the last type of table relationships is many to many. Basically, this is two sets of the previous type of relationship with a third junction table. As an example, we can use the same training company. And, again, we have the table with delegates’ records, the table with bookings and the courses table. The tables with courses and delegates will both be related to the bookings’ table using the one to many type of relationships. This will let each delegate to be assigned on multiple courses as well as allow each course have several delegates. In this case the table with bookings becomes the third junction table.

Linking your tables is an important skill to learn, when using the Access database, because it will add more functionality and give you more control over your database.

Most organizations need to store and maintain large amounts of various data. Many people have realized the benefits of using Microsoft Access database for storing and handling their data. MS Access is the most popular desktop database application for many reasons. It is relatively easy to use and offers a lot of functionality in entering, storing and extracting the data you need for work or personal purposes. Before using MS Access database you might consider taking special training to make the most out of the application.

So, after the data is entered into the database, it is useful to know how to extract it, when necessary. Let’s say, you want to check the sales data over a certain period of time. This kind of operation can be performed by using Microsoft Access queries.

You can learn about the work of Access database queries by looking at a possible scenario. For example, you find in an invoicing system that your office in New York needs a list of all European region sales for the current month. There are two ways to do that. One way is to make the list manually, looking through each record and writing down all information. This way is not practical in our age of technology and it will take a lot of time and effort f you have thousands of records held in your database.

More logical way would be to run a query, which will do all the hard work for you. To perform this task, you should open a query designer in your Access database and select the tables that contain the required data. Then you have to drag the necessary fields into the grid and write any required criteria for a needed field in the criteria line. According to our example, you would restrict the region to Europe. All the required data will be pulled back pretty fast, depending on the amount of information the system needs to look through in order to give you the needed result. This is how select queries work.

Access has other queries available. There are also action queries, which can be used to update, remove or add the data to the database, for example. Another kind of Access database query is called make table query. You can create a new table based on this query or another table. For example, you may wish to place all the invoice paid clients to a separate table. So, you can run the make table query to perform this, including the necessary criteria, and then create a table based on the query results.

Microsoft Access has many powerful objects and query is one of them. Making good use of Access queries will definitely show dynamic results in your work.

Judge how you are going to use DVD before you create DVD is a must. Your computer can be used to create a DVD using the DVD writer/burner provided.

There are some very effortless ways to burn DVDs , but features of the DVD can have limitation, e.g. it may not play back on the home DVD player. On the other hand , there are third party DVD authoring programs available that can help you create a complete, professional-quality DVD,. (You may already have such a program installed with the DVD writing hardware that came with your computer. For more information, please consult the documentation that came with your computer or DVD hardware.). Following are your options for making a DVD:

The simplest option is to follow the same procedure as if you were writing or “burn” your CD camcorder’s videos directly to a DVD, using the software on your computer. You do not need to purchase an additional program for this, and it is a fairly simple process. Writing files onto a DVD disc will result in an archive copy of your videos, but the disc will only play on computers with MPEG-4 video compatibility software installed (such as the 3ivx MPEG-4 Decoder installed by the Flip Video Program Program). The disc will not play in your home DVD player, as you must use an authoring program to create a DVD-compliant disc for your home DVD player. This option, then, is a good, simple way to archive your videos, but the resulting DVD has very limited use for playback.

The second option is to convert your videos into a format that is compatible with a wider variety of computers and home DVD players, and then burn your DVD using the utilities on your computer. There are a number of commercially available video conversion utilities (a.k.a. “encoders”) and these utilities are fairly low-cost products. This is a good option for creating a DVD for both archival storage and some limited playback on home DVD players. However, the first drawback of this option is that video conversion can be a fairly laborious and technical process, depending on which utility or application you choose (e.g. it can be tricky to choose the right conversion format, understand bit rates, etc.). Secondly, this process still does not author all the menus, titles, and navigation needed for a fully DVD-compliant disc, so that it plays on any standard home DVD player.

The third option is to purchase or use a program that allows for complete DVD authoring. This can be the most time-consuming and costly option, but it will result in a professional-quality DVD. DVD authoring programs can be time-consuming to understand and use, and are typically higher-cost programs, but they do enable you to convert your videos into the appropriate format for universal DVD playback, and to author all the menus, titles, and navigation needed for a fully DVD-compliant disc, so that it plays on any standard home DVD player. Most DVD authoring programs also allow you to edit your videos creatively, for example, shorten and splice videos, and add creative transitions to produce your own movie-like experience. This option requires the most time and cost, but also provides you with a DVD closest to a professional-quality DVD.

Frankly the refurbished computers are frequently the same as compared to the newest ones.

A laptop or computer that has been restored only means that the entire electronics, computer software, as well as computer specifications happen to be refurbished back to the way they were when they were new.
