Among the many Microsoft Office programs, MS Access takes an important place. Indeed, dealing with Access may cause some problems, especially if you are not keen on dealing with databases. Especially when you meet a lot of terminology. So let’s look closer at these tables. So far as is known, one table equals one entity. The latter may be any kind of information. There may be a linkage between the tables, so-called nominalization, so this may ensure that there wouldn’t be any duplication. This function make Access tables better then Excel ones.
The first steps in Access are rather simple – you just create a new database. The next step will be to create a table. Actually, there are several ways of doing it. You may select which variant to use: datasheet view, table design view, or just importing data from already saved program. After pushing Create –> Table, there will appear a window with active Add New Field. So you may add as many as you like and give them a name.
You should also know that there is an option here, which allows you to select any Table Templates from all available. So in this case Access will use the template to create a table with an active Add A New Field if you need to add some more. You may also add them later. Don’t forget constantly to save your table. The latter actually is a structure within your database. It means that you may create any number of tables in your database. If you want to specify a field description, use the Design view. In fact, this field is just text that will appear in a box over a database field. This is especially useful if this database is for several tables and many people will use it. The Design view is also helpful when you are dealing with custom data formats. Here you may create data validation schemes and insert some default values for data fields. Don’t forget that for each created field you will need to give a name, a description, a data type and properties.
In Access it is allowed to use the following data types: text, number, date/time, memo (for fields with information or notes), currency, autonumber, OLE object (insert information from other programs), yes/no, attachment, hyperlink, and lookup wizard (a list of possible values selected by the user). If you are making a descriptions it may be not more than 255 characters. Field properties consist of the acceptable data format; the field size; whether or not the field is required; any default values; and whether or not the table will be indexed on this field. Actually, that is all that you need to know how to operate MS Access.
