Practical tips for Table Design and Optimization

The Ms Access applicationimage76_w has enough versatility in it to be used as a backend for a multiuser line of business application in a small business setup. However if you are looking at receiving quick responses and avoid bloating up the Access database, certain best practices need to be followed. Let’s look at some practical tips to keep in mind when we are creating structures in the Access database and while working on it.

 

Avoid Creating too many Indexes

In case you have a table with a primary key, avoid creating indexes on other fields, unless it is truly required. An excess of indexes can overload a database and reduce its performance.

 

Use the Table Analyzer tool in Access

The Ms Access application comes with the table analyzer tool which can help you check the tables in database for flaws and possible improvements. It also comes rather handy in removing duplicate entries from an Access database.

 

Consider using appropriate data types for fields

During the table design phase, you get the chance to set the data type for the fields you create. Choose the data type relevant to the data you wish to store in that field and focus on selecting the most compact data type and field size that meets your requirements.

 

Use links while using OLE fields

In case you need to include files or images in an Access database, it is always advisable to include a link to the object in the OLE field instead of inserting the entire document. A bloated Access database with embedded files is a nightmare to maintain as it remains susceptible to MDB errors.

 

Split the database and Compact the Database at regular intervals

When you are looking to draw optimum performance from an Access database, you need to consider splitting the database into two parts. The one containing the application elements like forms and reports can be replicated on the users’ systems while central data file can be kept on a separate machine that acts as a server. Further you need to compact the database on regular intervals.

 

Protecting the data stored in Ms Access is a tough challenge

The Ms Access database can get compromised in case of a logical error or a hardware fault. In most cases the MDB data file is the first to succumb and this can compromise your entire data repository in one go. Now if you are looking to protect the data stored in Access tables, taking regular backups is a must. However it would not be enough to get back the latest datasets that were recorded since the last backup. So ideally you should keep an access repair tool like DataNumen Access Repair nearby which can get back all your data in proper shape. Compared to other recovery tools present on the web, it is not hampered by the storage media type and can even work on MDB files protected by passwords.
