Conversion Complexity Analysis

The time required to perform an Access to SQL Server conversion manually is governed exclusively by its level of software complexity – the amount of data in the Access tables is of little relevance. A simple and quick way to estimate software complexity is to count the number of tables, queries, forms, reports and modules (including class modules).

 If the total of these is in the low hundreds or less, then it is most likely that the database is of low complexity, requiring only days to weeks to convert manually. A total of less than 1,000 equates to medium complexity, which will require months to convert manually. However, a total of over 1,000 tables, queries, forms, reports and modules is generally indicative of a highly complex database which can typically take over a year to convert manually.

 The reason why complexity typically increases proportional to the object count of a database is because these objects need to communicate with one another by way of SQL Expressions. The more objects there are, the more permutations possible in how these SQL Expressions can be written.

 2SQL goes much further than the object count of a database to measure its complexity. On completion of a scan by the 2SQL Detective, a conversion estimate screen is displayed which shows a detailed analysis across the 30+ Conversion Categories, the number of issues for each category, the complexity rating, and the number of minutes to manually convert each issue.

CU2 Global, its service providers and/or a corporation’s own internal project team resources are able to perform detailed analysis of each Access application to be converted, utilizing the 2SQL Detective, in order to present company management with  both detailed and accurate time and cost estimates for each Access application conversion.
