This manual has concentrated so far on the manipulation of fields
within a relational database. As a text information server TEXIS
provides all the capabilities one would expect from a traditional
RDBMS.
TEXIS was also designed to incorporate large quantities of narrative
full text stored within the database. This is evidenced by its data
types as presented in Chapter here, Table
Definition. When textual content becomes the focus of the search,
the emphasis shifts from one of document management to one of
research. TEXIS has embodied within it special programs geared to
accomplish this.
Metamorph was originally a stand-alone program designed to meet
intelligent full text retrieval needs on full text files. Since 1986
it has been used in a variety of environments where concept oriented
text searching is desired. Now within the LIKE clause, all of what is
possible on full text information with Metamorph is possible with
TEXIS, within the framework of a relational database.
Metamorph is covered in a complete sense in its own section in this
manual and can be studied of itself. Please refer to the Metamorph
Intelligent Text Query Language sections for a full understanding
of all Metamorph's theory and application.
This chapter deals with the use of Metamorph within the LIKE portion
of the WHERE clause. TEXIS can accomplish any Metamorph search
through the construction of a SELECT-FROM-WHERE block, where the
Metamorph query is enclosed in single quotes 'query' following
LIKE.
