Below are the some important features of Data management
The information stored in database tables and records.
Different tools exist to deal with this data.
The schema map displays CI relations graphically.
Data word reference tables store structure and relationship definitions.
Data import and export simplifies managing large data sets through import maps and various exportable formats.
Different modules give extra functionality.
For Instance Field standardization makes records more reliable and prevents duplication of data.
Especially the majority of the data in the instances is stored in tables, which consists of a series of records. As a matter of fact the record thus holds a series of fields that hold the individual bits of information and can be viewed either as a list or a form.

Table can be related to each other in many ways:
Specifically a table can extend another table. The table expanding incorporates the majority of the fields of the other table (parent class) and includes its own fields. In particular For example, the Incident [incident] table has the majority of the Task [task] table fields (on the grounds that an occurrence is an exceptional type of errand) and has its own incident specific tasks.
One – to – Many: A field can hold a reference to a record on another table with in a table.
There are three types of one-to-many relationship fields.
Reference Field: It enables a user to choose a record on a table defined by the reference field. For example, the Caller field on the Incident table enables the user to choose any record on the User table.
Glide List: It enables a client to choose different records on a table characterized by the glide list. For Instance, the Watch list field on the Incident table enables the client to choose records on the User table.
Document ID Field: enables a user to choose a record on any table in the table. These fields are substantially less common, yet one example the Document field on the Translated Text [sys_translated_text] table.
Many- to – Many: Generally Two tables can have a bi-directional relationship, with the goal that the related records visible from the two tables in a related list.
Database Views: Two tables can joined for all purposes with Database Views to enable reporting on data that may put away stored over more than one table.
There are number of data a management tool that helps to manage the data.
Schema map: Subsequently The Schema Map shows the connections between tables visually, exploring through the database structure. The Schema Map gives an interface to review the connections between tables. The inter table connections it captures incorporate many-to-many relationships , tables that extend other tables, and tables that reference other tables through reference fields.
Data Dictionary Tables: Simultaneously Data dictionary tables hold data that characterizes the database and can accesses data on the database schema.
Table Cleaner: Simultaneously the system automatically records from particular tables after a particular time to deletion. Erasing these records naturally keeps the tables from developing to an unmanageable size. The time before a record deleted starts on the date and time value in the tracked field.
Prerequisites: It is good to have a knowledge on coding and data bases like SQL , MySQL. But it is not Mandatory .Trainers will teach you from the basics
