File>Database>Information

In Navision 3.01, native database version, if you go to File>Database>Information and click the Tables button there’s a column labeled Optimization. I was wondering what the numbers mean, is a low number better than a high number, what’s the range, etc.

Title changed from "Tables Question" to "File>Database>Information" because it is a better title for Navision Tips&Tricks

    -"No of Records": this is the number of records in the DB.
    -"Record Size": this is the size of 1 record (data + indexes)
    -"Size (KB): this is the total size the table uses (data + indexes)
    -Optimization : the higher the number, the more optimized the table is. This can be both good and bad.
    -If you have a table that you READ a lot and WRITE almost never (e.g. T15:"G/L Account") it is better optimized because an optimized table can be read faster. So this is a table you can optimize.
    -If you have a table that you WRITE a lot (independant of reading) (e.g. T17:"G/L Entry", T37:"Sales Line"), is is better NOT to optimize it, because optimizing speeds up for reading but slows down for writing. In general a table that is not optimized is between 50% and 60%.

    This was for a Navision DB. I suppose you have a Navision DB.

    I believe it's (data + indexes+sift tables + sift indexes)

    True. But SIFT-tables are partly data and partly indexes.

    Part of the table size though, although I don't know for sure if that is the case on SQL Server, since those are separate physical tables.
