A system, method apparatus, and computer readable medium for managing renewal of a dynamic set of data items. Each data item has an associated renewal deadline, in a data item management system. A renewal schedule allocates to each data item a renewal interval for renewal of the data item. On addition of a new data item, if a potential renewal interval having a duration required for renewal of the data item, and having an ending at the renewal deadline for that item does not overlap a time period in the schedule during which the system is busy, the renewal schedule is automatically updated by allocating the potential renewal interval to the new data item. If the potential renewal interval does overlap a busy period, the renewal schedule is automatically updated by selecting an earlier renewal interval for at least one data item in the set.

Renewal management for data items

Visual structuring of multivariable data sets provided in records which include fields, and are displayed in tabular form. A method comprising: defining a key field; sorting records by defined key field; finding equivalent field values in fields in records arranged adjacent to each other; defining a block for fields having equivalent field values; displaying one field value of fields of a block having equivalent field values and masking all other fields within the block having equivalent field values like the one field value. Facilitating monitoring or analysis of large multivariable data sets provided in records and displayed in tabular form it is proposed to define blocks of fields having equivalent field values and display only one field value of a block. The visual output is useful to identify patterns indicative of an attack. A service provider monitors records provided by a customer and notifies the customer of the attack.
