Http://martin.kleppmann.com/2012/12/05/schema-evolution-in-avro-protocol-buffers-thrift.html When you want to store data, such as objects or other types of data, to a file or transmit data over the network, you need to face the serialization problem.For serialization, each language provides corresponding packages, such as Java serialization, Ruby's marshal, or Python's pickle. Everything is fine, but if you consider cross-platform and language, you ca

If we want to know what the relationship is between the user and schema in the database, let's first look at what the user and schema are in the database. in SQL Server2000, user and schema always have an implied relationship because of the schema. It is very rare to realize that the user and

If we want to know the relationship between user and schema in the database, we must first understand the concept of user and schema in the database. In sqlserver2000, because of the architectural reasons, the user and schema always have a layer of implicit relationship, so we rarely realize that the user and schema ar

on are allocated in segments. When you create a table, a table segment is created, and an index segment is created when an index is created. Each object that consumes storage space is eventually stored in a single segment. There are rollback segment, temporary segment, cluster segment, index segment, etc. A tablespace is a logical container that is associated with a data file and a table space that has at least one data file associated with it. A table space can have multiple segments, and a se

Schema scheme, logical classification of database objects4. User users, equivalent to

The Schema file looks very similar to other XML files. it is composed of a group of elements, and its root element is "Schema ". The Schema element is the first element in XMLSchema to indicate that the XML document is a Schema document. The End mark of Schema is usually at

SPRING1 uses the DTD format, Spring2 later uses the schema format, using the schema format, supports different types of configuration has its own namespace, so that the configuration file has a better extensibility.No matter what, are both pros and cons, using the schema format, bean.xml file header declaration will be relatively complex very much, whenever I see

Label:When a SQL query is a reference table, you need to develop a schema name for it. in the terminology of a database, a pattern is a namespace . This way you can combine objects of the same nature into a common namespace. The schema can also protect the object, so the DBA can grant display permissions to the pattern. For example, a DBA can grant a user the SELECT permission for a pattern so that the user

Schema is a language used to describe and standardize the logical structure of XML documents. It is used to verify the correctness of the logical structure of XML files. It can be understood as similar to DTD (document type definition), but schema is superior in the current web development environment. Because it is a valid XML document, you can understand the XML structure more intuitively. In addition, th

From the definition, we can see that the Schema is a set of database objects. To distinguish each set, we need to name this set.
