A database engine and optimizer framework support creation of a series of profiling indices over a column having character string data, such as a traditional “varchar” data type. The profiling indices result in a reduction of the number of records that are searched when searching for a sub-string match within that column. In some embodiments, the series of indices are created over a column that is typically searched using the LIKE predicate or some similar technique; these indices indicate for each record whether certain sub-strings may exist in that record's value in the column. Thus, the indices are used to find the rows that may match one or more portions of the particular term being queried or, in other words, eliminate those records that do not have at least a portion of the term to be matched. The number of records actually retrieved and searched for the query sub-string is thereby reduced.

A method, apparatus and program storage device is provided for dynamic data formatting during transmittal of generalized byte string data across a computer network. Remote server dynamically changes format of each column string data value from the result set separately, according to actual size of the string data value, and returns it to a client.

A system and method for processing of markup language information, such as extensible markup language (XML) based control information is disclosed. The system comprises a compression sender entity and a decompression receiver entity. The sender entity uses its internal, binary representation derived from textual XML-based protocol header and encodes the binary representation as a tag-length-value (TLV) binary value. The TLV binary value is embedded as encoded data in a specifically marked comment, which may be detected by the receiver entity. The receiver entity builds up an internal, binary data structure based on the encoded data representing the original XML data. The system avoids the usage of string data to represent a small set of well known strings and uses a more compact binary encoding which reduces space and time to process the data.

A computer-readable recording medium recorded with a printing program causes a processor of a computer to calculate a rendering area of print data stored in a storing section of the computer as a primary area based on the print data, and to calculate a rendering area of commentary string data to be attached to the print data as a sub-area. The program then judges whether the primary area and the sub-area overlap, and whether the sub-area deviates from an effective printing area. The commentary string data can be changed so that the primary area and the sub-area do not overlap, and so that the entire sub-area is within the effective printing area, if at least one of the judgment results in the judging step is affirmative. The changed commentary string data then is attached to the print data.
