Microsoft Access is a database creation and administration program. To comprehend Access, you should first comprehend databases.
In this lesson, you will find out about databases and how they are utilized. You will acquaint yourself with the contrasts between information administration in Microsoft Access and Microsoft Excel. At last, you will advance a look beyond at whatever is left of the Access instructional exercise.
Watch the video below to learn more about databases in Access.
What is a database?
A database is a gathering of information that is put away in a PC framework. Databases enable their clients to enter, get to, and break down their information rapidly and effectively. They’re such a valuable instrument, to the point that you see them constantly.
Ever paused while a specialist’s assistant entered your own data into a PC, or watched a store worker utilize a PC to see whether a thing was in stock? Provided that this is true, at that point you’ve seen a database in real life.
The least demanding approach to comprehend a database is to consider it an accumulation of records. Consider one of the databases we said over: the database of patient data at a specialist’s office.
What records are contained in a database like this? To begin with, there’s a rundown of patients’ names. At that point there’s a rundown of past arrangements, a rundown with medicinal history for every patient, a rundown of contact data, etcetera.
This is valid for all databases, from the easiest to the most unpredictable. For example, in the event that you jump at the chance to prepare you may choose to keep a database containing the kinds of treats you know how to make and the companions you give these treats to. This is one of the least difficult databases possible. It contains two records: a rundown of your companions, and a rundown of treats.
Notwithstanding, in the event that you were an expert pastry specialist, you would have numerous more inclines to monitor: a rundown of clients, a rundown of items sold, a rundown of costs, a rundown of requests, et cetera. The more records you include, the more mind boggling the database will be.
In Microsoft Access, records are somewhat more mind boggling than the ones you compose on paper. Microsoft Access stores its arrangements of information in tables, which enable you to store much more point by point data. In the table beneath, the People list in the beginner pastry specialist’s database has been extended to incorporate other important data on the bread cook’s companions.
On the off chance that you know about different projects in the Microsoft Office suite, this may help you to remember Excel, which enables you to sort out information comparatively. Truth be told, you could manufacture a comparable table in Excel.
Why utilize a database?
In the event that a database is basically a gathering of records put away in tables and you can assemble tables in Excel, for what reason do you require a genuine database in any case? While Excel is extraordinary at putting away and sorting out numbers, Microsoft Access is far more grounded at taking care of non-numerical information, similar to names and portrayals.
Non-numerical information assumes a huge part in any database, and it’s critical to have the capacity to sort and dissect it.
In any case, the thing that truly separates databases from some other method for putting away information is network. We call a database like the ones you’ll work with in Microsoft Access a social database. A social database can see how records and the items inside them identify with each other.
To investigate this thought, how about we backpedal to the straightforward database with two records: names of your companions, and the sorts of treats you know how to make. You choose to make a third rundown to monitor the clusters of treats you make and who they’re for.
Since you’re just influencing treats you to know the formula for and you’re just going to offer them to your companions, this new rundown will get the majority of its data from the rundowns you made before.
See how the third list uses words that appeared in the first two lists? A database is capable of understanding that the Dad and Oatmeal cookies in the Batches list are the same things as the Dad and Oatmeal cookies in the first two lists. This relationship seems obvious, and a person would understand it right away; however, an Excel workbook wouldn’t.
Excel would treat all of these things as distinct and unrelated pieces of information. In Excel, you’d have to enter every single piece of information about a person or type of cookie each time you mentioned it because that database wouldn’t be relational like an Access database. Simply put, relational databases can recognize what a human can: If the same words appear in multiple lists, they refer to the same thing.
The fact that relational databases can handle information this way allows you to enter, search for, and analyze data in more than one table at a time. All of these things would be difficult to accomplish in Excel, but in Access even complicated tasks can be simplified and made fairly user friendly.
