Oracle SQL Tutorial 6 - Relationships and Primary and Foreign Keys - Database Design Primer 3
 
29:40
HAPPY VALENTINES DAY!!! Let's talk relationships.. This is the 6th video in your Oracle Database series. We are discussing database relationships which are a key feature of relational database management systems. We first discussed entities and attributes. I talked about how each entity is assigned a table and each attribute is a column within a table. We moved on to the three kinds of relationships. The first was one-to-one. This describes an entity and an attribute. A piece of data that is exclusive to an entity is, by definition, an attribute of that entity. This is stored in one table with the attribute being a column within this table. The second relationship is one-to-many. This relationship is between two entities. The way we properly store this in a database is using a foreign key in the child table. Remember, the child table is the entity on the many side of the one-to-many relationship. Every row within the child table will have a value for the foreign key that references a primary key in the parent table. This assumes that the foreign key field is not optional (NOT NULL). If the foreign key is optional, than a reference is not required but any reference must be valid. The third kind of relationship is a many-to-many relationship. In this situation, we need 3 tables. The many-to-many relationship is broken up into two one-to-many relationships. The intermediary table will associate each entity from one table with the appropriate entities in the other table. There is debate as to whether this table needs a primary key. This is because you can intact use the combination of two foreign keys as a primary key. This works because we will never have two duplicate rows within the intermediary table and the two foreign keys work as a compound key because of this. We finally discussed primary keys and foreign keys. Primary keys are used to keep each row inside of a table unique. If this key is a computer generated number it is known as a surrogate key, otherwise it is known as a natural key. Natural keys have real world meaning. For example, a social security number may work, or an email address (in some situations), etc. Whichever type of key you choose is solely up to you and/or the company you may be working for.

How to find all database constraints with SQL in Oracle.
 
14:49
I have written a small sql code to find out all database constraints. Just be sure you have dba permission, otherwise you might not view all constraints. To see constraints separately for dba and user you can use user or dba instead of all, like user_constraints or dba_constraints, user_cons_columns, dba_cons_columns. I have used all_ to find out everything instead in a single query.

Database Design: Surrogate keys | what is Surrogate key? | Surrogate key in SQL
 
09:54
Surrogate keys are auto incremented numbers that have no real world meaning. Auto incremented means that each row will have the next highest number. Keep in mind that the one that you should use can vary depending upon the purpose of your database. Surrogate key example Surrogate primary key SQL surrogate key What is a surrogate key? Surrogate key definition Follow me: https://www.facebook.com/munir.du https://twitter.com/munir_du https://www.linkedin.com/in/md-munir-hussain Contact me: [email protected] Surrogate Key In Database Design =========================== In database design, it is a good practice to have a primary key for each table. There are two ways to specify a primary key: The first is to use part of the data as the primary key. For example, a table that includes information on employees may use Social Security Number as the primary key. This type of key is called a natural key. The second is to use a new field with artificially-generated values whose sole purpose is to be used as a primary key. This is called a surrogate key. A surrogate key has the following characteristics:  Surrogate key is a unique identification key, it is like an artificial or alternative key to production key, because the production key may be alphanumeric or composite key but the surrogate key is always single numeric key.  It is typically an integer.  Surrogate key is system generated artificial primary key values.  Surrogate key is a substitution for the natural primary key.  It is just a unique identifier or number for each row that can be used for the primary key to the table. The only requirement for a surrogate primary key is that it is unique for each row in the table.  It has no meaning. You will not be able to know the meaning of that row of data based on the surrogate key value.  It is not visible to end users. End users should not see a surrogate key in a report.  Data warehouses typically use a surrogate, (also known as artificial or identity key), key for the dimension tables primary keys.  It is useful because the natural primary key (i.e. Customer Number in Customer table) can change and this makes updates more difficult. Way to generate surrogate keys: Surrogate keys can be generated in a variety of ways, and most databases offer ways to generate surrogate keys. For example, Oracle uses SEQUENCE, MySQL uses AUTO_INCREMENT, and SQL Server uses IDENTITY. Use of surrogate keys: Surrogate keys are often used in data warehousing systems, as the high data volume in a data warehouse means that optimizing query speed becomes important. Using a surrogate key is advantageous because it is quicker to join on a numeric field rather than a non-numeric field. There are no hard rules on when to employ a surrogate key as opposed to using the natural key. Often the data architect would need to look at the nature of the data being modeled and stored and consider any possible performance implications. The following are examples of when it makes sense to use a surrogate key: When different source systems use different keys for the same record. When we integrate the systems, instead of picking one set of keys, it is often better to use a surrogate key. Thanks for linking, commenting, sharing and watching more of our videos

What is KEY-VALUE DATABASE? What does KEY-VALUE DATABASE mean? KEY-VALUE DATABASE meaning - KEY-VALUE DATABASE definition - KEY-VALUE DATABASE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A key-value store, or key-value database, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, a data structure more commonly known today as a dictionary or hash. Dictionaries contain a collection of objects, or records, which in turn have many different fields within them, each containing data. These records are stored and retrieved using a key that uniquely identifies the record, and is used to quickly find the data within the database. Key-value stores work in a very different fashion from the better known relational databases (RDB). RDBs pre-define the data structure in the database as a series of tables containing fields with well defined data types. Exposing the data types to the database program allows it to apply a number of optimizations. In contrast, key-value systems treat the data as a single opaque collection which may have different fields for every record. This offers considerable flexibility and more closely follows modern concepts like object-oriented programming. Because optional values are not represented by placeholders as in most RDBs, key-value stores often use far less memory to store the same database, which can lead to large performance gains in certain workloads. Performance, a lack of standardization and other issues limited key-value systems to niche uses for many years, but the rapid move to cloud computing after 2010 has led to a renaissance as part of the broader NoSQL movement. Some graph databases are also key-value stores internally, adding the concept of the relationships (pointers) between records as a first class data type. Key-value stores can use consistency models ranging from eventual consistency to serializability. Some support ordering of keys. Some maintain data in memory (RAM), while others employ solid-state drives or rotating disks. Redis was the most popular implementation of a key-value database as of August 2015, according to DB-Engines Ranking. Another example of key-value database is Oracle NoSQL Database. Oracle NoSQL Database provides a key-value paradigm to the application developer. Every entity (record) is a set of key-value pairs. A key has multiple components, specified as an ordered list. The major key identifies the entity and consists of the leading components of the key. The subsequent components are called minor keys. This organization is similar to a directory path specification in a file system (e.g., /Major/minor1/minor2/). The “value” part of the key-value pair is simply an uninterpreted string of bytes of arbitrary length. The Unix system provides dbm (DataBase Manager) which is a library originally written by Ken Thompson. The dbm manages associative arrays of arbitrary data by use of a single key (a primary key). Modern implementations include ndbm, sdbm and GNU dbm.

Oracle SQL Tutorial 5 - Database Integrity - Database Design Primer 2
 
12:18
This is the second video in the 5 database design videos in my oracle sql tutorial series. This video discusses database integrity. Database integrity is broken up into 3 sections: entity integrity, referential integrity, and domain integrity. Entity integrity focuses on the primary key. A primary key should be unique, NOT NULL, and never changing. It should refer to only one individual entity. Referential integrity focuses on protecting the relationships between entities of different tables. When creating relationships between tables, you will associate a column with another column in a different table. Individual entities inside of this table should have relationships with individual entities in the other table. For example, a comment table might have a user_id column. Each individual comment (each row), should have a user_id that points to a user_id in the user table. We protect referential integrity with what are known as foreign key constraints. Domain integrity focuses on the allowed values within a database. This one is probably the most complex because there are so many different things you can do to protect this, some of which involve a server side scripting language to add even more complex rules such as regular expressions. Fortunately, Oracle SQL is a pretty big database system and surely has lots of features that can be used to allow domain integrity.
