If your SQL database is the back end or foundation of your ERP, then applications are your business’s engine powered by its fuel. Your database is like a warehouse crammed with irreplaceable business history, intelligence, and the ingredients for business continuity. Yes, you need to keep your operation in shape and agile, so like the rest of your business, you must "right-size" your database. Right-sizing is the planning process that goes into the preliminary database design. You may have transitioned from Excel spreadsheets to the MS Access database because your spreadsheets became so deep and wide that you couldn't see all the trees in the forest. Databases are deep, but they must be kept as narrow as possible through sensible design. There are lots of great tactics to apply to keep databases agile and efficient. For example, an Access database text field can hold as many as 255 characters. So, if you're designing a table with a 255-character field that will never hold more than 20 characters, your database will eventually become unnecessarily fat and slow.
