What is as400 database




















Ensuring mission critical applications remain available in the event of planned and unplanned downtime events will undoubtedly save a company money in the long run. Unplanned disasters are typically not the costliest or even common TCO measurement.

Availability events that cause the most disruptions and affect business continuity on a AS system, are almost always related to planned downtime events. Back Contact Company History. Search Products.

Midland encourages companies to download and compare AS software products, because it is important to know what you are buying before it is too late.

Encryption, Masking, Scrambling and Tokenization Any AS DB2 database file with sensitive data should be encrypted or have a similar data protection mechanism in place to mask or hide the original data.

Auditing, SIEM and Ticket System Integration Software The AS system has many different event log sources that contain security, operational, performance and application event details that may be required to identify and isolate critical incidents, which may need to be incorporated into your corporate SIEM or Ticketing System. Database Replication, Conversion, Migration and ETL Projects Our database replication tools can convert data to and from almost any database format on different OS and hardware platforms, and keep the disparate databases synchronized in real time and without locking source or target database files.

IBM i Encryption. IBM i Security. Job Scheduler. Guy Dehond from Inventive Designers was one of the beta-testers of Silverlake. Dr Frank Soltis, the chief architect, says that this is the main difference between this and any other operating system. There are several types of character strings.

Each string can be categorized further into one of the types shown in the following table:. Data in which every character is represented by a single character set.

The length of a mixed-data character string is its total number of bytes, counting two bytes for each double-byte character and one byte for each single-byte character. A character string is a sequence of bytes. The length of the string is the number of bytes in the sequence. If the length of the string is zero, then this is called the empty string. This string should not be confused with NULL. All values of a fixed-length character string column have the same length. This is determined by the length attribute of the column.

The length attribute must be between 1 and All values of a varying-length character string column have the same maximum length, which is determined by the length attribute of the column. The length attribute must be from 1 and Table provides definitions of each character string. This is a fixed-length sequence of characters that must be treated as binary data ranging in length between 1 and This is a varying-length sequence of characters ranging in length between 1 and 32, This is a varying length sequence of characters that is to be treated as binary data ranging in length between 1 and 32, Large object data types store data ranging in size from zero bytes to 15 megabytes.

There are three large object data types:. A character string comprised of single-byte characters with an associated code page. This data type holds text-oriented information, where the amount of information could grow beyond the limits of a regular VARCHAR data type upper limit of 32K bytes. The Migration Workbench supports code page conversion of the information and compatibility with the other character types.

A character string comprised of double-byte characters with an associated code page. This data type holds text-oriented information where double-byte character sets are used.

This data type has a maximum length of A graphic string is a sequence of two-byte characters. The length of the string is the number of its characters. Like character strings, graphic strings can be empty. All values of a fixed-length graphic string column have the same length, which is determined by the length attribute of the column. The length attribute of the column determines the maximum length that a value can have.

A data type where every character is represented by a character from the double-byte character set. Table provides definitions of each graphic string. This is a fixed length graphic string of Length graphic characters. Length can range between 1 and This is a varying length graphic string of up to Length graphic characters. Length can range between 1 and 16, All numbers have a sign and a precision. The precision is the total number of binary or decimal digits, excluding the sign.

The sign is positive if the value is zero. Two-byte binary integer with a precision of 5 bits. Four-byte binary integer. With a precision of 10 digits. An eight-byte large binary integer with a precision of 19 digits.

A floating-point number. The precision is the number of digits, which can range between 1 and A precision value between 1 and 24 indicates a single-precision, floating-point number.

A precision value between 25 and 53 indicates a double-precision, floating point number. If you do not specify a precision value then this is a double-precision, floating-point number. A single-precision, floating-point number is a bit approximation of a real number with a range of 1. A double-precision, floating-point number is a bit approximation of a real number with a range of 2. A double-precision floating-point number, which is a bit approximation of a real number.

The range of this data type is 2. A packed-decimal number. The precision is the number of digits and can range between 1 and The scale is the number of digits to the right of the decimal point and can range from 0 to the value specified for precision.

The position of the decimal point is determined by the precision and scale number of digits in the fractional part of the number of the number. All values of a decimal column have the same precision and scale. Zoned-decimal number. Although date data types are used in certain arithmetic and string operations and they are compatible with certain strings, they are neither strings nor numbers. This was expanded to 64 bits with the original release of the AS A number of processors do operate on bit data.

Most modern CPUs such as the Pentium and PowerPC have bit vector registers used to store several smaller numbers, such as 4 bit floating-point numbers. A single instruction can operate on all these values in parallel SIMD. They are bit processors in the sense that they have bit registers and in some cases a bit ALU, but they do not operate on individual numbers that are binary digits in length.
