13、 the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC te
14、chnical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1.
15、 Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.

32、ge), since the commands for accessing are based on SQL-functionality (see IS0 9075) and coded according to the principles of interindustry commands as defined in ISOAEC 7816-4. The database itself is a structured set of database objects called a database file DBF. Under a DF thare shall be not more
33、than one DBF which is accessible after selection of the respective OF. A database may be also directly attached to the MF. Fig.1 shows an example for the embedding of a database in the card. 2 STDOBSI BS ISO/IEC 78Lb-7-ENGL 1999 D Lb2LibbS 0794774 3bO H BS ISOAEC 7816-7:1999 I MF I r - 5 -.- -1 Appl

35、 SQL- API (API = Application Programming interface). Thus, a card carrying a SCQL database may appear as a part of a distributed SQL database environment.

Each object can be referenced by a unique identifier. A table is a structured
37、data object with a unique name within a database. It consists of named columns and a sequence of rows. The number of rows may be conceptually unlimited (Le., only restricted by the available memory space in the card), or limited. The table and the main characteristics are shown in fig. 3. 3 BS ISODE
38、C 7816-71999 I Characteristics: - Table name: unique, max. 8 characters - No. of tables: not regulated by this standard - Column name in table: unique, max. 8 char. - No. of columns within a table: 1 - 15 - Max. no. of rows: not determined or fixed - Column size: O - 254 bytes, if not specified - Co
39、lumn data type: string Figure 3 - SCQL table (example) and its main Characteristics After creation the table structure is persistent, .e. neither an existing column can be withdrawn nor a new column can be inserted. On a table the following actions can be performed: - read (select) - insert - update
40、 - delete. 5.3 SCQLviews A view is a logical subset of a table, which defines the part of the table accessible. Two types of views are to be distinguished: - a view (see fig. 4), which by definition fixes the accessible columns, is called in this context a static view and - a view (see fig. 5), whic
41、h restricts the access to those rows whose contents matches defined conditions (e.9. to rows the value of which is greater 20), is called in this context a dynamic view. Static view wth access restriced to the 2nd and 3rd column Figure 4 - SCQL static view (example) 4 STD.BSI BS ISO/IEC 78Lb-7-ENGL

A view
43、 has like a table a unique name in a SCQL database. Several views may be defined on the same table. On a view the following actions can be performed: - read (select) - update. 5.4 SCQL system tables and dictionaries A system table is maintained by the card and contains information necessary to manag
44、e the database structure and access. There are three system tables: - the object description table (name *O) - the user description table (name *U) - the privilege description table (name *P) The object description table contains information about the tables and views stored in the database. The use
45、r description table contains information about the users which have access to the database. The privilege description table contains information about the privileges onto the database tables and views. Privileges describe which tables and views can be accessed by which users, and which actions can b
46、e performed by those users on the respective table or view. The figures 6 - 8 show the system tables with their mandatory columns. 5 O (Object description table) I OBJNAN OBJOWh OBJTYP OBJDES OBJOPT I I I I I Object Object Object Object name owner type descriptor (table (user id) (T = table, (column

49、 information contained in the system tables, views on these system tables can be created. A view on a system table is called a SCQL dictionary. The only action which a user can perform on a dictionary is reading (select). 5.5 SCQL user profiles SCQL user profiles are characterized by special permissions. A user profile is attached to a user identifier stored in the user description table. Table 1 shows the profiles and the attached permissions.
