Dependent or not on database software, how can one calculate (for tell) a disk space required for a certain/huge amount of records for one's database. Here's a sample single table design: Transactions Table TransactionCounter AutoIncrement Long TransactionId Number Long TransactionDate Date/Time StockCode Number Long Quantity Number Short Sub-Total Number Short Remarks String * 30 Posted Boolean Thanks!

Just because databases store data differently and some are more sloppy than others. However one great article you can check out refers to how you can estimate the size of a database based on its tables, clustered/non clustered indexes, and heap. Estimating the Size of a Database - SQL Server - MSDN The factors can be applied to many other databases. By knowing the size of indexes, calculating the overall storage size of tables based on the length of fields * number of rows, and calculating the heap you can get a good approximation. That would be a great place to start the search.
