The Common Requirements To A Database Developer

A lot of companies have a big amount of data to store and manage that is why they look for people with good experience in MS Access development. There are a lot of chances they will need some skills in programming. One of the common requirements to a database developer is to take the current system and change it as well as being able to create a totally new system.

Planning a new system usually requires a lot of documentation and meetings. So it is important for a developer to have skills to decipher the planning documents. The project also usually has a project manager assigned to it. And the manager’s job is to supervise the programmer’s work to make sure all the specifications are met. But it doesn’t mean that the programmer cannot make suggestions as to the specification changing.

There are different specifications, which include bad and god ones. The worst specifications have no screen layout, so the programmer has nothing else left to do but guess. Specification needs to have a workflow diagram and textual version.

After getting familiar with the specification document, the next stage is the MS Access development. This stage may involve creating basic screen models with little functionality. After creating those, you can show them to the project manager or users. It is better to get approval of your work, before going on with other tasks, because you may risk delivering work that wasn’t really expected or asked for.

When looking through the specification document, make sure you transfer all the entities outlined there to the database tables. If there are any relationships between the entities, you should build relationship links between the tables. It is not compulsory but this is how it typically works in database development.

If you received screen diagrams, you should use the MS Access form designer to create a working screen. Always use correct controls. So, you can apply a combo box for certain items. When you need to enter a long text or description, always use memo fields for this. If you will need to use multiple records in form, then a good idea is to use MS Access subform and link it to the main form. Or, apply a pop up form with the subform in it, which is linked back to the main form.

Always check you use the correct data types in the tables. Don’t enter text into the numeric field, for example.

MS Access is considered to be a great tool for prototyping. You can easily put together the core elements of the system and use it as a demo database. So, make sure the MS Access database you develop corresponds to the specification you obtained.

The world of computers and computer applications expands all the time. But you can turn this issue into your strong point by catching up with this knowledge and becoming an expert, for example in microsoft access database niche.

Microsoft Access Training Courses

Many people are taking Microsoft Access training courses, because they realize that even though it is quite a complex program to master, it is still very useful. Even though a lot of us use Excel for managing and storing data at our jobs, but Access is a much better choice. After your Microsoft Access training, you will see that it will be a great advantage for your career.

Microsoft Access is database, which you can use to store data in tables that can be related to each other. For linking tables you need to have field in each table that can be related. If you store similar data in multiple tables, it makes each table smaller than if you put all information in one file like in Excel. It is also easier to add or change the information, because you will have to enter data for each type of table in one place.

When you start your Microsoft Access training, the first thing you will learn is how to enter the data and structure your database. Among all the ways to do it, the easiest one is to enter the data directly into the table. You will see rows and columns in table’s interface, where you can enter data. If you manage the database, but you still need to let other people, who are not as familiar with Access, to enter data, you will have to make a data entry form for them. With the forms, inexperienced users can enter data into the database with having fewer chances to make a mistake and having access to fewer fields in the table.

Query is considered to be the most powerful tool among other objects of Microsoft Access. Queries allow you interact with the database on a bigger scale. You can use query to extract data from the system setting up certain criteria. And you can also use queries to even change the data. After building a query you can get all the information you extracted right into an Access report and then print it out. Creating effective queries would be one of the most important parts of your Microsoft Access training. But, learning all that will make your job much easier and productive compared to other employees in your company.

Microsoft Access is a very powerful application for storing, managing and analyzing data. After your Microsoft Access training you will be able to see that using a difficult to handle Excel program for managing data wasn’t really worth it, because now you can use a much more effective and productive Access database. In just a matter of weeks after you buy a good Microsoft Access training course, you will be able to see good changes in your career.

Creating Reports WiTh Microsoft Access Software

One of the useful functions in Access database is to create reports. There are two report formats in MS Access database – columnar and tabular. Report in tabular format look like spreadsheet you can see in Excel or other spreadsheets applications. In columnar reports every column is devoted to one record. You can also create multi-column reports in 2007 edition of Access.

When you create multi-column report, you are able to efficiently and neatly report data in a single page. When you set one up, keep in mind that this page will have two or more columns with data. But you will be working with a single column in the layout mode. And the effect of multiple columns will only be seen during the preview or when you print the report page.

Each report column will have the same margins you set up for the master column. So it is important to define the margins and their visible width, this way making sure that no report elements go beyond the set width. At the top of the master column you will see the horizontal ruler, which will show you the width of the column. Another way to set up the width of your column is going to Layout and selecting the Ruler command. After you define the width of the columns, you should adjust the width of the entire report, for it to match the column width.

You can also make adjustments to the report, column or printing setup in the Page Setup tab. In order to make changes to the column options, go to the Column tab through the Page Setup dialogue window. You can choose the number of the report to have and column and row spacing as well in the Grid settings. The spacing is used to add space between rows or columns.

Setting the width and height of the column is possible in the section Column Size. You will see the default margins, which are reflecting the ones you have set earlier. In the Height box you are able to control the maximum record height.

And in the section of Column Layout, you can make Access to report your records before the new column or in rows across the page. After you are done setting up the Access 2007 multi-column report, click OK and you can preview the report just to make sure it looks the way you want. In case you need to make more adjustments, go to page setup and make some changes to the report if necessary.

Microsoft Access 2007 has so many useful feature and functions and creating reports is only one of them. It might be a little tricky to use Access in the beginning, but after some learning and practice, you will be able to make the most of it.

The industry of computers and computer applications expands all the time. But you can turn this issue into your advantage by catching up with this knowledge and becoming a pro, for example in microsoft access database niche.

Over the years of programming Microsoft Access, some best tips and practices have been found out that are the most important in developing the best database. If these rules were violated, it could cause errors, slow performance, database corruption and other difficulties in database work.

So, in order to improve the form performance and the loading of drop down list, you should use optimized by Access stored queries as the sources for your records. The Access wizard will create form with Select SQL record sources and this is not the best option.

In order to prevent errors in data entry, make the possibility of what information can be entered in a field restricted. You can use a message window or onscreen area to inform the use what is required. In order to increase the performance speed, index the criteria selection fields in your queries and fields in queries that are linked to the tables. Another way to increase the speed of processing is to use the least amount of memory and place by optimizing the data types.

Add code error handling to routines, in order to know what logic to apply. When an MDE file stops working, it won’t inform you about anything useful on how to fix the error.

Give your users the access only to the copy of the front end database. It will contain everything except for the data. By restricting access to the original front-end database, you will prevent the possibility of unexpected database corruption. Make sure you always split the database into back end and front end. The back end data should be placed on the network share root, which will make it quicker to read it and write. And don’t forget to compact the back end data regularly. This will let you know if there are any corrupted data records or table indexing. And compacting will also reduce the size of the file.

While compacting the data, check if your Access subversion is up to date, so you don’t have to reissue the previous auto numbers. The copy of original MDB should also be made. In the network, do not use fields with memo data type. These fields have different indexing, which is more prone to corruption during the server write-back.

When you link tables to children tables, use auto number fields. Users find them difficult to modify and they perform better indexing. In order to prevent duplicate records, check for potential duplicate using the code, instead of using multi-field key. In the multi-user environment, avoid using record sets unless they are only read snapshot.

These are some of the most important database developing rules you should follow, in order to improve its performance speed and prevent corruption.

Microsoft Access Database Knowledge

For a proper database design you need a little more than just the knowledge obtained in MS Access training. Getting more experience is necessary for all database projects, except the most basic ones. Database optimization or also known as normalization is a set of the best practices of designing the database. One of the sets of these rules is called First Normal Form and it is one of the most basic ones.

The first rule is not to duplicate fields. You learn the basic database pattern on MS Access courses, where there are rows, records, fields, etc. So, if you have a database of sales representatives, every row will represent one sales person. And fields in each record will store the information like name of the person, etc.

Sales territories can also be displayed in the fields and let’s say that the sales territories of the company are broken down by city. So, each sales representative can have several cities assigned but every city has only one rep. That is why it would be a mistake to use multiple fields like City1 and City2 for them. If a sales person has one city, the City2 filed will be blank and it will waste space. All city queries will have to look for information on both City fields. And if the sales representative with three assigned cities appears, you will have to rebuild the whole database.

Combining fields is not the right solution either. You shouldn’t create one “Territory” field and enter as many cities as you want there. It might seem like a solution to a problem, but the field is still duplicative.

The right decision is to create multiple records and not fields. Don’t enter duplicative information into one record. It seems logical to have one record for each employee, but in this case it is better to have multiple records, only if they are unique. So you would create separate records for different cities, even if they have the same rep. Usually, territory records should be stored in a separate table, as the employee table will have other information you don’t have to repeat. Then you can link the territory table with the employee table, but in order to do that you need to have a field in common. In order to avoid further errors, it is not recommended to use the employee name as the common field, in case, another employee with the same name is hired.

A good solution would be having IDs for all employees in the main employee table. You should use that ID in the territory table instead of the employee name. It will prevent errors in queries and provide uniqueness to the identifier.

The industry of computers and computer applications grows all the time. But you can turn this issue into your advantage by catching up with this knowledge and becoming an expert, for example in microsoft access database niche.
