# Data Model

**Objects**

Objects hold a specific type of record, like a category of record. Objects contain records of a specific type, as well as their attributes and values. Object is like a worksheet in a spreadsheet or a table in a database.

Objects are standard (available in all workspaces), recommended (the ones you can create to unlock functionality by using defined semantic names) and custom (specific to your business and workflows).

**Records**

A record in Bigdelta contains information about a specific item or entity. A specific person or a specific company are the most common examples of records in Metrical. Record is like a row in a spreadsheet or a database.

**Properties**

Properties are customizable data points added to your records in Bigdelta. An example attribute might be a record’s location, where they work, or when your last email interaction was with them. Attributes are like columns in a spreadsheet or a database.

**Relations**

Relations are links between related records from different objects. Relation attributes allow you to connect records and show the bidirectional relationship between them. Updating the value of a relationship attribute on one record will also automatically update the value on any connected records. You can associate a person with a company, company with people, feedback with a person, a subscription with a company, etc.

**Events**

Events are either captured actions of people / users or captured impart system changes. Events are immutable, i.e. you can not edit event properties.
