Field help (AETANO)

When an anomaly is found in a table, the corresponding line is displayed in color (the color depends on the gravity of the anomaly).

The anomalies that exist are :

• anomaly of type 1 : the number of lines in the table is greater that 3 times that planned at the start. The relation between the two is given in the text for anomaly.
• anomaly of type 2 : the number of extents on the data or the index exceeds 30.
• anomaly of type 3 : number of colors too great or the size (on integrating the blobs) is too large.

These anomalies are likely to pose performance problems.
