414:. IBM subsequently acquired the database division of Informix in April 2001, making UniVerse and UniData part of IBM's DB2 product family. IBM subsequently created the Information Management group of which Data Management is one of the sub-areas under which the IBM U2 family comprised UniData and UniVerse along with the tools, SystemBuilder Extensible Architecture (SB/XA), U2 Web Development Environment (U2 Web DE) and wIntegrate.

Thus the first three fields of this record, including the record ID and trailing field mark, would use 49 bytes of storage. A given value uses only as many bytes as needed. For example, in another record of the same file, JOHN JONES (10 bytes) may be replaced by MARJORIE Q. HUMPERDINK (21 bytes) yet

Rocket
Software Universe and Unidata have limited ability to create web-based front-ends to Universe/UniData content. Since Rocket Software provides SQL access to its database products, a SQL-based product can be used to build a web-based UI to the databases; regardless of using Files or Tables in

Files are made of records, which are similar to rows within tables of a relational database. Each record has a unique key (called a "record ID") to distinguish it from other records in the file. These record IDs are typically hashed so that data can be retrieved quickly and efficiently.

Both UniVerse and UniData support TLS transport level data encryption and record and file level encryption of data at rest using OpenSSL. Additional API encryption functionality is also available to allow custom solutions or meet specific regulatory requirements.

Fields may be broken down into values and even subvalues. Values are separated by value marks (character xFD); subvalues are separated by subvalue marks (character xFC). Thus, if John Jones happened to get a second email address, the record may be updated to:

strings; there is no binary data stored in U2. For example, the hardware representation of a floating-point number would be converted to its ASCII equivalent before being stored. Usually these records are divided into
