Database-related size criteria

When planning the size of your database, use the formulas described in the following table to calculate the approximate amount of disk space (in bytes) required for a database. For limits on any of these elements, see OpenEdge Data Management: Database Administration.

Table 15. Formulas for calculating database size
Size	Formula
Database size	schema size + data table size + index size
Schema size	Typically, between 1 and 100MB¹
Data table size	Sum of individual table sizes
Individual table size	number of records x field storage x 1.5
Index size	Sum of individual index sizes
Individual index size	number of records in the table being indexed x (7 + number of fields index +field storage ) x 2

¹ To determine the schema size, load the schema into an empty database and check the size of your database—this is the size of your schema.
