    • WA_USER_TEXT

      CREATE TABLE WA_USER_TEXT ( WAUT_U_ID INT, WAUT_TEXT LONG VARCHAR, PRIMARY KEY (WAUT_U_ID) ); CREATE TEXT INDEX ON WA_USER_TEXT (WAUT_TEXT) WITH KEY WAUT_U_ID;

    • WA_USER_TAG

      CREATE TABLE WA_USER_TAG ( WAUTG_U_ID INTEGER NOT NULL, -- the id of the user of whose tag it is WAUTG_TAG_ID INTEGER NOT NULL, -- the id of the user who gives the tags WAUTG_FT_ID INTEGER NOT NULL, WAUTG_TAGS VARCHAR NOT NULL, PRIMARY KEY (WAUTG_U_ID, WAUTG_TAG_ID) ); CREATE UNIQUE INDEX SYS_WA_USER_TAG_FT_ID ON WA_USER_TAG (WAUTG_FT_ID); CREATE INDEX WA_USER_TAG_TAG_ID ON WA_USER_TAG (WAUTG_TAG_ID);

    • WA_TYPES
      1. Contains list of registered ODS's application types.
      2. Based on this table information ODS can create instances of each application.
      3. Typically, each application should store necessary information in this table during installation. For example:

        INSERT REPLACING WA_TYPES(WAT_NAME, WAT_DESCRIPTION, WAT_TYPE, WAT_REALM) VALUES ('WEBLOG2', 'Blog', 'db.dba.wa_blog2', 'blog2')



        CREATE TABLE WA_TYPES ( WAT_NAME VARCHAR, WAT_TYPE VARCHAR, WAT_REALM VARCHAR, WAT_DESCRIPTION VARCHAR, WAT_MAXINST INTEGER, PRIMARY KEY (WAT_NAME) );

    • WA_MEMBER_MODEL
      1. Contains list of available ODS application member models.
      2. Now, it's:
        • Open - each ODS user may became application member without any restrictions. Application owner will not be informed.
        • Closed - no-one may become new member
        • Invite only - only application owner can invite ODS users to become application member
        • Approval based - ODS user can became application member only after application owner approval
        • Notify owner via E-mail - each ODS user may became application member without any restrictions. Application owner will be informed automatically by email.

          CREATE TABLE WA_MEMBER_MODEL ( WMM_ID INT PRIMARY KEY, WMM_NAME VARCHAR NOT NULL );

    • WA_MEMBER_TYPE
      1. Contains list of available application-specific (for each registered application) membership types.
      2. For example: author, reader. Owner is not a member type, and is provided by another ODS mechanism.

        CREATE TABLE WA_MEMBER_TYPE ( WMT_APP VARCHAR, WMT_NAME VARCHAR, WMT_ID INT, WMT_IS_DEFAULT INT, PRIMARY KEY (WMT_APP, WMT_ID)) );

    • WA_INSTANCE
      1. Contains detailed information about each of created application instances.
      2. WAI_NAME field values MUST BE EQUAL to corresponding application_object.wa_name value. If any application wants to change values provided by ODS - it should check equality.
      3. WAI_NAME should be unique through the whole table.

        CREATE TABLE WA_INSTANCE ( WAI_ID INT IDENTITY, WAI_TYPE_NAME VARCHAR REFERENCES WA_TYPES ON DELETE CASCADE, WAI_NAME VARCHAR, WAI_INST WEB_APP, WAI_MEMBER_MODEL INT REFERENCES WA_MEMBER_MODEL, WAI_IS_PUBLIC INT DEFAULT 1, WAI_MEMBERS_VISIBLE INT DEFAULT 1, WAI_DESCRIPTION VARCHAR, WAI_MODIFIED TIMESTAMP, WAI_IS_FROZEN INT, WAI_FREEZE_REDIRECT VARCHAR, WAI_LICENSE LONG VARCHAR, PRIMARY KEY (WAI_NAME) ); CREATE TEXT INDEX ON WA_INSTANCE (WAI_DESCRIPTION) WITH KEY WAI_ID USING FUNCTION; CREATE INDEX WAI_TYPE_NAME_IDX1 ON WA_INSTANCE (WAI_TYPE_NAME)

    • WA_MEMBER
      1. Contains detailed information about each of member of each application instance.
      2. WAM_MEMBER_TYPE - corresponds (as foreign key) to WA_MEMBER_TYPE table.
      3. WAM_STATUS contains ODS-specific (not application-specific) application member status
        • 1 - owner
        • 2 - approved
        • 3 - awaiting approval from owner
        • 4 - awaiting approval from user
      4. ODS application SHOULD NOT work with this table directly (except for READ operation to determine member type and status)
      5. All necessary action with this table will be done by ODS itself automatically.

        CREATE TABLE WA_MEMBER ( WAM_USER INT, WAM_INST VARCHAR REFERENCES WA_INSTANCE ON DELETE CASCADE ON UPDATE CASCADE, WAM_MEMBER_TYPE INT, -- 1=owner, 2=admin, 3=regular, -1=waiting approval, etc. WAM_MEMBER_SINCE DATETIME, WAM_EXPIRES DATETIME, WAM_IS_PUBLIC INT DEFAULT 1, -- Duplicate WAI_IS_PUBLIC WAM_MEMBERS_VISIBLE INT DEFAULT 1, -- Duplicate WAI_MEMBERS_VISIBLE WAM_HOME_PAGE VARCHAR, WAM_APP_TYPE VARCHAR, WAM_DATA ANY, -- app dependent, e.g., last payment info, other. WAM_STATUS INT, PRIMARY KEY (WAM_USER, WAM_INST, WAM_MEMBER_TYPE) ); CREATE INDEX WA_MEMBER_WAM_INST ON WA_MEMBER (WAM_INST);

    • WA_MEMBER_INSTCOUNT

      CREATE TABLE WA_MEMBER_INSTCOUNT ( WMIC_TYPE_NAME VARCHAR REFERENCES WA_TYPES ON DELETE CASCADE, WMIC_UID INT REFERENCES SYS_USERS (U_ID) ON DELETE CASCADE, WMIC_INSTCOUNT INTEGER DEFAULT NULL, PRIMARY KEY (WMIC_TYPE_NAME, WMIC_UID) );

    • WA_INVITATIONS

      CREATE TABLE WA_INVITATIONS ( WI_U_ID INT, -- U_ID WI_TO_MAIL VARCHAR, -- email WI_INSTANCE VARCHAR, -- WAI_NAME WI_SID VARCHAR, -- VS_SID WI_STATUS VARCHAR, -- pending, or rejected PRIMARY KEY (WI_U_ID, WI_TO_MAIL, WI_INSTANCE) ); CREATE UNIQUE INDEX WA_INVITATIONS_SID ON WA_INVITATIONS (WI_SID);

    • WA_DOMAINS

      CREATE TABLE WA_DOMAINS ( WD_DOMAIN VARCHAR, -- domain name WD_HOST VARCHAR, -- this and rest are the endpoint to access wa via that domain WD_LISTEN_HOST VARCHAR, WD_LPATH VARCHAR, WD_MODEL INT, PRIMARY KEY (WD_DOMAIN) );

    • WA_MAP_HOSTS

      CREATE TABLE WA_MAP_HOSTS ( WMH_HOST VARCHAR, WMH_SVC VARCHAR, WMH_KEY VARCHAR, WMH_ID INTEGER IDENTITY, PRIMARY KEY (WMH_HOST, WMH_SVC) );

    • WA_VIRTUAL_HOSTS

      CREATE TABLE WA_VIRTUAL_HOSTS ( VH_INST INTEGER REFERENCES WA_INSTANCE (WAI_ID) ON DELETE CASCADE, VH_HOST VARCHAR, -- this and rest are the endpoint to access wa via that domain VH_LISTEN_HOST VARCHAR, VH_LPATH VARCHAR, VH_PAGE VARCHAR, PRIMARY KEY (VH_INST,VH_HOST,VH_LISTEN_HOST,VH_LPATH) );

    • WA_BLOCKED_IP
      1. Used internally by ODS to prevent unlimited login (failed) attempts from the same IP address.

        CREATE TABLE WA_BLOCKED_IP ( WAB_IP VARCHAR, WAB_DISABLE_UNTIL DATETIME, PRIMARY KEY (WAB_IP) );

    • WA_INDUSTRY

      CREATE TABLE WA_INDUSTRY ( WI_NAME VARCHAR NOT NULL PRIMARY KEY );

    • WA_COUNTRY

      CREATE TABLE WA_COUNTRY ( WC_NAME VARCHAR NOT NULL PRIMARY KEY, WC_CODE VARCHAR, WC_LAT REAL, WC_LNG REAL, WC_CODE VARCHAR );

    • WA_PROVINCE

      CREATE TABLE WA_PROVINCE ( WP_COUNTRY VARCHAR, WP_PROVINCE VARCHAR, PRIMARY KEY (WP_COUNTRY, WP_PROVINCE) );
