Data & Databases

<img src="database.jpg" alt="databasemodules">

That is to say that there’s a little less concern with us being well-known. We can stand up for being good data specialists because we know the right questions to ask. The kinds of assumptions that large corporations are likely to make may be very different from the things that individuals are likely to make. If we can clarify what the individual does and what the team as a whole does, we stand a chance of getting a good process in place. This is a very informal talk, very informal indeed. My only advice is that if I did get a little personal about it, that was perfectly understandable.

But I’m a data expert, and so are my brother and sister, and we live together in India. If we’re getting personal and don’t like each other and don’t want to go on holiday with each other and explain ourselves, how do we expect data professionals to get a good process into place?

Database records are stored as a tree, sorted by certain attributes, and linked to each other through certain identifiers. If you can list all database records, all entities that exist on the database, and all entities that exist in the current database but haven’t been populated into the database yet, you can save both time and storage costs.

This type of data structure allows each new database record to store a lot more information than a simple array does. At each level of the tree, you can create a new record, and more importantly, you can add each existing record to the database one level further.

This is a simplistic view of how a database works. A database is a program that can read, write, save, and delete the information as it needs to. More complex types of databases, such as database mergers, allow for inserting and removing information at various levels within the database.

This type of data structure allows the database to grow, but only when certain conditions are met. There are many kinds of data models. Some of the most common ones include

1) Hierarchical database model 

2) Relational model

3) Network model

4) Object-oriented database model

5) Entity-relationship model

6) Document model

7) Entity-attribute-value model

8) Star schema

9) The object-relational model, which combines the two that make up its name
