Microsoft Access has many useful objects and one of them is macro. Macro adds more functionality and control to your Access database. You can create macros to perform almost any task in your database and it is not that hard. Using macros is the next step of using building and designing your database after mastering all the basics like tables, forms, queries and reports. But it is still easier than writing VBA code for Access. You can quickly learn to use macros and automate some of your database tasks to save your time and effort. There are different macros in Access and one of them in autoexec macro.

This macro runs as you start the database. So, this macro can be assigned to perform any tasks you want at this time. For example, you may wish to open a particular form and move to creating a new record. This is easy to do with macro. You should go to the macro designer and add new task of running the form and creating a new record. Then, you should save the macro naming it AutoExec. Close the database properly and then run it again. You will see that the macro will kick into action and you will see your assigned task performed.

Autoexec macro in Access can be assigned with any actions you wish. You might also wish to backup the data, when the database opens. You can assign an action to transfer the data or even objects to another database. You can also create a make table query for making the data backup and then run this actions in Autoexec macro. If you want to run a delete query with a macro, then you have to set the warnings to be incorrect in the macro.

Usually it is better to perform simple actions with Autoexec macro in Access. If you want to avoid running Autoexec macro then you can hold the shift key when your database is opening. The macro will not start and the database will run as usual.

You can choose any form to load when the database is opening, but a good choice of a form is a login form. When your system loads, login form will be the first thing you see. At this point you can also minimize the database window.

So if you load the macro designer and improvise with different macro actions, you will be able to add more functionality and control to your database. Adding macros to your basic database functions, you will be thrilled at what your Access application can do. Using macro is not that hard and you can learn to create them after an advanced Access training and then practicing it with your database application.

If you want to create the best possible Microsoft Access database, then this article might be useful to you. The items described in this article have been proved to be the main causes of slow performance, user difficulties, errors and data corruption in databases. Avoiding these mistakes will help you prevent minor or major database problems. So, here are the guidelines you should follow.

In order to increase the form’s performance and the loading of the drop down list, you should use the stored queries as the source of your record, because Access has already optimized them.

It is also important to use validation rules. This will help prevent errors due to data entry, because you will be able to restrict what information can be entered in the field. Let your user know what is required by using a message box. If you use the fields tag property, it will be easy to encode the type of validation for each field. Then you can simply loop through the fields list to select the validations. In order to increase the performance speed, you can also index the fields used in queries that link to the tables and the fields used as criteria in queries.

You can also increase the processing speed and using fewer amounts of storage and memory by optimizing the data types.

In order to have control over the solving database problems, always add code error handling to your routines. MDE file can stop working without letting you know anything useful about the error. For the same reason you shouldn’t use macros which do not allow trapping errors, except for menus.

Let users access only a copy of the front end database, which has everything except data. Never allow users access the original front end file. This way you will prevent the risk of unforeseen corruption. Make sure you always split the database into front end and the back end. The back end data should be placed on the network share and it should be compacted regularly. This will let you see if any data is corrupted or if any table indexing is corrupted. It will also reduce the file size.

When you link tables to dependent tables, use auto number field. They give better indexing and are harder for users to modify.

If you want to check for a potential duplicate data, use a code instead of multi-field key, which prevents duplicate data. You should also use the same name in related tables. Avoid using record sets in a multi-user environment unless it is a snapshot. And on large updates of record set, use BeginTrans and CommitTrans operations in order to speed up the updates by storing them in memory buffer temporarily.

These are some of the important points you should use, if you want to create an efficient and functional Access database and reduce the risk of corruption.

Many Access database users consider creating a form quite easy. But, unfortunately, not every user is aware that each form also has property settings, which we can changed to control form’s look and behavior. In this article you will find out how to manage form’s properties from a property sheet. You will also learn some of the common property settings in Access form.

Form properties are rules, which control everything about a form like its look and functions. All MS Access objects have their own properties. Then, all form controls like text box, label etc also have their own set of properties. You can access these properties through the property sheet. To open a property sheet, click on the button at the form’s top left corner. You will see different categories the properties are grouped in such as format category, data properties, event properties, other properties and the all category.

The format category has the properties, which control the look of the form. You can apply these properties, if you want to define the look of the form and what items you want in the form. You can set up scroll bars and navigation buttons in the form.

Property sheet has a lot of different properties, so it will be hard to remember all of them. But if you need to learn about a particular property, you can simply select it and press F1. On a help page, you will get a short explanation and examples of how to use the property.

The data properties allow you to control things like the source of the data, whether you should allow other users to edit, delete or enter data and what kind of things users can do with the data.

Event properties are used to determine actions taken upon an occurring event like opening of the form or data update, etc. You can assign an action for each property to perform by clicking on the builder button. This will open the Choose Builder dialogue box letting you determine the action.

Other properties category has miscellaneous items, which can be very useful for designing your form. There are different properties like Pop Up and Modal. So you can make your form appear like a pop up window. Or if you use Modal property, the form will have the exclusive focus and you will have to close the form first, if you want to move the focus somewhere else.

And, logically, the all category contains all properties together. A long list of different properties is available for you to use, change your form and define different form functions. Each of them can help you optimize your form as you wish and give you more control over your form.

Microsoft Access database has lots of useful features and one of them is combo boxes. Using combo boxes will improve the look and feel of your Access forms. In order to understand the work of combo boxes, let’s consider the example of countries.

Access forms may require different information like name, address or country. And as we know some countries’ names can be recorded in few ways, for example the United Kingdom is also known as the UK, England, Britain, and Great Britain. And if you have entered a different name of the country every time you wanted to record the United Kingdom, it might cause some problems. If you want to run a query and search for all customers in the UK, you will get a wrong result. The query will show you all the customers registered under “the UK”, but will not show other records you might have entered as “Britain” or “England”, for example. You will also have the same problem with the United States.

Another problem, which may arise, is an incorrect spelling of the name of the country. One time you might record country as Brazil, and the next time you might spell it as Brasil. And again you will get wrong results in your search.

The solution to this problem is using a dropdown box or MS Access combo box. Using combo boxes will also speed up the process of data entry, because you will not have to type the data in, but select it from the list.

MS Access combo box can use table or a query as its data source. It is probably better to use a query, just because you can filter the data you need in a query. Imagine that you need only European countries in your form, so using a query you can set the needed criteria. Besides, queries work faster than tables, which will also improve your performance.

It is not that hard to create a combo box for any type of information you store in your database. And you can also use the Access Wizard for this purpose, which makes the process even easier.

When you use a combo box in Microsoft Access, you don’t have to worry about entering the wrong information in the database, which often leads to problems. Every record you have to create in Access database will always have the same items to select from, which prevents typing in the same information in different variations. You will simply select the one correct data item from a combo box and your data as well as the form will be more consistent. Learning how to create and use combo boxes in Access can prevent many database problems and save time.

Microsoft Access database has many tools and objects for performing different tasks. One of the main objects in Access database is a table. Access tables are used to hold data. Each table is made up of columns, which can be also called fields or attributes. Each of the fields has a particular data type defining the information it can store. So, if you need to enter numeric information like prices, you should use number or currency data type fields. If you need to enter first or last name, the best data type field would be the text one. A memo data type is an alternative to a text data type field. MS Access memo field is used to store text, but the difference with the text data type is that it can store a lot more text than the general field.

There are certain times when we should use memo data type fields. They are best used in cases when we have to enter notes or description. Sometimes we need to store a lot of data about a transaction or one of the customers and that is when we would use memo data type.

Usually, when we use form, we would make the size of the memo text box bigger and set its main property to New line in field, which will allow us to prevent the data bunching together in one long paragraph. But you should keep in mind that we cannot index or sort MS Access memo fields. These fields also have limitations when used in queries. But you would actually avoid using memo fields in queries that is why it is not a big issue.

If you use MS Access 2007, you can apply rich text formatting in the memo field both in form as well as datasheet views. In order to perform this, you should set the text format feature of the memo field for it to become Rich Text.

You always have to make sure that you use the correct data types in your database. Very often this aspect is discovered through the trial and error experience, but a proper planning can greatly improve your Access database performance. This is also one of the aspects learned during the Microsoft Access training, which is highly recommended to take for every Access user before creating a database. Proper Access database learning can give you more confidence in using the software and also let you prevent many database development mistakes, therefore, saving a lot of time for you. Microsoft Access is complex software and even though it provides a great level of flexibility, database users still have to follow rules for the application to work properly and prevent data loss.

Microsoft Office has many useful applications for us to use such as Word, Excel, Outlook and Access. Each program requires good skills and understanding if you want to make the most out of it. And one of the hardest applications among all of them to learn is probably Access. This application is the hardest because you need to know the program that is Microsoft Access as well as have good understanding of the database theory and terminology. So, if you want to use Access for your business needs you should definitely learn it first.

There are different ways to learn any subject. And you can learn Access database in various ways also. You can look for information about the application on the Internet, purchase a book or register for Microsoft Access classes. If you choose the third option, you should also decide whether you want to learn online or wish to learn the subject in the classroom with the other people and the trainer. A lot of people have their own learning preferences, but many still prefer the convenience of taking the online course. It gives them the opportunity to log on to it any time they want and wherever they want.

If you have Microsoft Office suite on your computer, you probably know that Access can be very tricky. So, before using it, you will surely benefit from the right guidance from a reliable source. But, the problem is that not all publications will give you the whole information and will guide you through every little and important step from the very beginning till the end, which will help you master the Access application. Most people, who have learned Access in one way or another, gathered a whole library of different hand out notes about this database application. All these notes contain a lot of hot air and theory filled with computer jargon. Not all people understand computer jargon and such kind of reference material has low chances of inspiring people to learn the database further. It is always more inspiring to have colorful screen shots and different diagrams to show students how the application works and give them a better idea of what is going on.

If you decide to learn Access using online sources, you will see that things are very different there. During online Microsoft Access classes you will be able to learn from step by step video lessons, which will be supported by colorful documentation. You will be able to have access to other online students and the trainer. This is also a great help to every Access student in mastering this database application and being able to make the most of all its functions. That is why many people agree that the best way to learn Microsoft Access is via online classes.

All pieces of software we use on our computer require repair and regular updates in order to keep their optimum performance. And Microsoft Access application is not an exception. It also needs initiatives, which will maintain the database application in a perfect health and minimize or eliminate errors as much as possible. Read this article to find out what MS Access problems you may encounter and how they can be handled.

If you use Microsoft Access software frequently, you will often come across different problems during the usage. One of the worst issues among all other database errors, crashes and glitches, Access database corruption is considered to be the worst. Database corruption makes the whole application simply useless and it can also jeopardize your job, because the data becomes inaccessible. Whether you often encounter database corruptions or have never had them yet, you need to look at the methods of fixing such problems, as they can be an indication of other database issues.

Usually, Access database corruption can mean a serious software error, which can range from missing files to an outdated Access installation. Here are some of the common reasons for Access database corruption.

First is the improper database shut down. It is the most typical reason for database corruption. Bad software shut downs can lead to sudden disconnections of the database from its front end part and make it very vulnerable. If you fail to repair the database immediately by Access utility, you risk having permanently corrupted database and even losing some data.

Second possible reason for Access database corruption is improper shut down of the operational system. Performing a proper system shut down will automatically close MS Access application. But different system freezes and crashes can also lead to improper database shut downs, which can also make the database corrupted.

Even though performing the compacting of your database is useful from time to time, doing it too much hoping to speed up the work of application is not good. Frequent database compacts makes Access vulnerable to damages and corruptions and can put the application at risk thus making you repair the database errors in order to prevent corruption.

Microsoft Access database is quite complex as well as sensitive. And even if a user is trying to be completely cautious about the database state, making sure the database is always healthy, it is not always possible to prevent all problems. You can get yourself a peace of mind if you have some kind of third party database repair software. Having a powerful database repair program, which can fix all Microsoft Access errors and recover your database from corruptions, is a great solution for the constant problem of Access database repairs.

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.

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.
