Table boundary detection in data blocks for compression

1. A method of identifying table boundaries in data blocks for compression by a processor device in a computing environment, the method comprising:

converting data into a minimized data representation using a suffix tree by sorting data streams according to a plurality of symbolic representations for building table boundary formation patterns, wherein the converted data is fully reversible for reconstruction while retaining minimal header information, wherein in conjunction with the sorting the data streams according to the plurality of symbolic representations, textual data is represented by a first symbol, numerical data represented with a second symbol, and a delimiters used for separation is represented by a third symbol; and

performing a scanning operation according to each of the following:

searching a suffix of each of the sorted data streams for identifying a data sequence that includes the first and second symbol representing the textual and numerical data,

skipping the data that only includes the third symbol until identifying the next data sequence that includes the first and second symbol representing the textual and numerical data,

building the suffix tree for the converted data, and

eliminating each scan-order not matching the searching and the skipping.

2. The method of claim 1 , wherein the textual data is a sequence of characters not included in a delimiters list and a digits list, and the numerical data is a sequence of digit characters not included in the delimiters list.

3. The method of claim 1 , further including, in conjunction with the sorting, matching together those of the table boundary formation patterns that are similar for identifying a longest minimized data representation table boundary formation pattern.

4. The method of claim 3 , further including, performing at least one of:

reordering each of the table boundary formation patterns to form an output data file, and

adding to a header of the output data file at least the table boundary formation patterns, a number of rows of the output data file, and a third symbol used for separation of the table boundary formation patterns.

5. The method of claim 3 , further including, in conjunction with the matching, searching for node branches within the suffix tree.

6. The method of claim 1 , further including, performing the converting for a plurality of data type blocks.
