Microsoft Access is a simple solution for any business or professional who needs a unique database. Keeping its limitations in mind, it can provide the right solutions for small projects and groups to maintain data.
Microsoft Access is a surprisingly divisive application. Its primary purpose is as a simple relational database, but the larger that database becomes, the more difficult it can be to work with Access. It is possible to process large database with special technologies, but ultimately it is best to use the simple database for basic projects so that you never have to worry.
At its core, Microsoft Access is a solid database solution that is part of the Microsoft Office Suite. One of the biggest draws to Access is the fact that it has a much lower cost than many other database solutions. Also the software is packaged with a lot of other apps that you need. It contains everything required to develop and maintain a relational database.
Primary Elements
There are certain universal elements to relational databases:
- 形式
- Tables
- Reports
- Relationships
- Queries
- Macros
- Modules
Access does have all of these components. If you are a beginner, that is fine. You probably are not going to use the more advanced components until later, particularly macros and modules. The first five elements listed are vital for being able to create and develop even the simplest database.
Software Limitations
One of the reasons so many people disparage Access is because of the issues that occur once the software reaches the far end of its limitations. To properly develop and maintain your relational databases, you should plan for this eventuality.
The following are the limitations inherent to working with Access.
| Table Size Capability | Up to 1 GB |
| Maximum fields (record or table) | 255 |
| Maximum fields (index) | 32 |
| Maximum indexes (record or table) | 10 |
| Maximum tables (query) | 32 |
| Maximum form or report size | 22 inches |
| Character limit (memo) | 64,000 |
| MDB | 2GB |
| Maximum integer count | 2,147,483,648 |
| Simultaneous users | 255 |
Relational Database
With these limitations in mind, you need to understand what a relational database is. The purpose of relational databases is to provide a way to view a lot of data at one time. These databases are bound by a few specific rules.
- Avoid duplicate data
- Divide data into manageable groups
- Data should be presented as the smallest unit, such as name, address, or phone number
- Enter data for one component as a record
- Identify each record as a unique entity
Essentially, relational databases take the information from a form and store all of the data in a way that is easy to retrieve and compare with other forms that have been entered. The data is shown on tables and pulled with queries. To do this, each record must be uniquely identified.
Issues and Fixes
Nearly everyone has encountered issues with databases. It is likely you know how frustrating and upsetting it can be when they do not work properly, and Microsoft Access is no exception. When you set up an Access database, you need to monitor it carefully to ensure it does not exceed its limitations. You also need to plan for future growth. Other databases are certainly costlier, but they can better handle large amounts of data.
